Automatic transmission chevrolet cruz do it yourself repair

In detail: automatic transmission Chevrolet Cruze do-it-yourself repair from a real master for the site my.housecope.com.

Today the car of the Chevrolet Cruze brand is one of the most popular among our compatriots. This model is reliable, attractive and comfortable.

Cruz is available in different trim levels, with the installation of different volumes of power plants. Also, this model is found with a manual transmission and automatic transmission. In this case, we will have to get to know in more detail the models that have an automatic transmission, as well as find out the possible causes of malfunctions and how the Chevrolet Cruze automatic transmission is repaired.

The car turned out to be reliable, but there are no eternal cars, as we all know, this trouble has not been spared by the Chevrolet Cruze lineup, which often suffer from machine malfunctions.

The automatic transmission of this model has decent quality and reliability, but sooner or later it needs repairs or scheduled maintenance. Which, in turn, will help you forget about the likelihood of a necessary automatic transmission repair for a long time. This mechanism includes the following components:

solenoid block of automatic transmission Chevrolet Cruze;
gears of each of the 6 gears;
rotating and camshafts;
electrical control unit for the mechanism;
Chevrolet Cruze gearshift cable;
shift gate of automatic transmission Chevrolet Cruze;
sensors, the presence of oil and control of the operation of the automatic transmission, as well as the output shaft sensor;
oil and oil filter;
air conditioning system, or as it is used to call the automatic transmission cooling radiator.

All these components are collected in one single mechanism and provide smooth acceleration for the Chevrolet Cruze car. In case of failure of at least one component, the automatic transmission will have to be repaired.

If there is no oil in the automatic transmission of the Chevrolet Cruze or not enough oil to circulate throughout the system. Then you can expect an imminent failure of such a mechanism as an automatic transmission. Therefore, the oil level in the box should be checked regularly and, if necessary, always top up, as well as the cause of the fluid leaving the closed system should be found.

As a rule, a mechanism such as an automatic transmission on a Chevrolet Cruze lasts a long time and, with high-quality and timely maintenance, it does not require repairs. However, due to negligent use by a car and skipping scheduled maintenance, they can significantly reduce the service life of even such a reliable element of a car as an automatic transmission.

For Chevrolet Cruze, automatic transmission repair can cost different costs. It all depends on the malfunction that needs to be eliminated. The most expensive moment in terms of repairs will be the replacement of the electrical control unit, which can cost the owner of a foreign car the whole cost of a new automatic transmission. If the cause of the malfunction lies elsewhere, then, as a rule, no more than 50-60 thousand rubles will have to be spent on the repair of the Chevrolet Cruze automatic transmission. For such a complex mechanism, the price is low. All this is due to the low cost of spare parts for the Chevrolet Cruze, in contrast to other car brands, where automatic transmission repairs can cost 100-200 thousand rubles.

Also, the Chevrolet Cruz automatic transmission output shaft sensor will noticeably hit the car owner's pocket, since it will not be possible to find it in any store, it is recommended to immediately contact an official dealer of the Chevrolet Cruze brand in your region. The replacement part is extremely rare in conventional stores and requires a qualified technician to replace it. Since incorrect installation of this element can completely ruin the machine.

In this case, it makes no sense to give an example in which the car starts but does not drive. Consider the most common signals that a motorist can receive from a car in the event of an automatic transmission malfunction:

on the Chevrolet Cruze model, the automatic transmission kicks, the most popular case when repairs are required is ejection from the gear when it is turned on;
at speed, a whistle or a metallic rustle is heard from under the hood - this indicates that the oil level in the Chevrolet Cruze automatic transmission is less than required;
when accelerating at a certain speed, the car jerks sharply, which indicates the failure of one or more gears of the automatic transmission;
on the Chevrolet Cruze model, the automatic transmission twitches - this may also indicate a malfunction of the output shaft sensor or the rotating shaft itself;
when shifting into reverse gear, you feel a jolt or a characteristic jerk - this indicates a disruption in the transfer shaft.

As a rule, these malfunctions indicate an imminent failure of the mechanism. If the car starts up and does not move after engaging the gear, then the problem has to be looked for either in the control unit or in the clutch mechanism of the gearbox with the flywheel.

Serious breakdowns can be avoided with timely scheduled inspections of the automatic transmission in the appropriate car service. As a rule, here you will be told how long the mechanism can work without interruption and when to visit a service to repair the mechanism.

Earlier, we have already announced some approximate prices for repair services for the restoration of an automatic machine on this car. In this case, the price tag for repair work should be considered in more detail so that car owners understand how important it is not to save money and undergo scheduled maintenance of the Chevrolet Cruze automatic transmission in a timely manner:

The average cost of removing and then installing a Chevrolet Cruze automatic transmission in different salons is about 8,000 rubles.
Replacing failed units, excluding the cost of parts, will cost you an average of 8,000 rubles.
A complete bulkhead of the automatic transmission will cost the car owner an average of 12,000 rubles.

Thus, having carried out a total calculation, you can answer the question, how much does it cost to repair an automatic transmission on a Chevrolet Cruze? This pleasure will cost you an average of 30,000 rubles, taking into account the fact that you yourself will pay for the purchase of spare parts for the mechanism that need urgent replacement. Which usually amounts to a decent amount too. In other words, for the repair or complete restoration of the gearbox, you have to spend at least 40 thousand rubles.

In this case, one cannot but agree that it is significantly less costly to spend about 2-3 thousand rubles once a year on diagnostics than to spend every 5-6 years on automatic transmission repairs. In any case, timely service will cost you several times less.

In the case of the Chevrolet Cruze I restyling, does the automatic transmission break down, which raises a lot of controversial questions. Here, as a rule, another automatic transmission model is installed, the service life of which has been significantly increased. However, this is a non-eternal mechanism that will work continuously throughout life. This box also requires regular maintenance and timely troubleshooting, which can be performed by a qualified Chevrolet official technical service technician.

Malfunctions in the automatic transmission cooling system

Very often, the cause of a malfunction of the Chevrolet Cruze automatic transmission is the overheating of this mechanism. The automatic gearbox has its own cooling system, which, although united into a common one, has its own separate cooling element. Often the reason for the refusal to work lies in this particular part of the car.

Often, not qualified specialists in car services can sin on breakdowns of the mechanism itself and offer you to make expensive repair work or even replace the automatic transmission, but you should not rush into this.First of all, pay attention to the cooling system. Perhaps the problem lies in it. Of course, if it breaks down, the automatic transmission control unit will not allow the mechanism to work until the cooling begins to work properly. On the Chevrolet Cruze, the replacement of the air conditioning system is carried out in official service centers, since the workers of an ordinary workshop can do the work incorrectly, after which you will not leave with such a cooling system for long, and it will not work out in the workshop that the cause of the next breakdown was not your fault.

In this case, we examined the most common causes of a malfunction of such a complex mechanism as an automatic transmission on a Chevrolet Cruze, which can often let you down at the most inopportune time. In order to prevent these unpleasant consequences, and not to be left far out of the city alone with the problem, it is better to perform the procedure of a diagnostic examination of a Chevrolet Cruze car before a long trip, which will save you from unnecessary unforeseen and significant costs.

The Chevrolet Cruze 1.6 and 1.8 l car in various modifications is equipped with several models of a five-speed manual and six-speed automatic transmission 6Т30 / 6Т40 / 6Т45.
In practice, the vehicle has shown itself to be a fairly reliable machine, while the automatic transmission provides the optimal mode of gear shifting in almost any road conditions and individual driving style. In the Chevrolet Cruze automatic transmission scheme, a traditional planetary scheme with modern electronic automation is used, and a working failure or failure of at least one element of the automatic transmission leads to the failure of the entire unit, which requires repair intervention or a complete replacement.

There are no eternal mechanisms, therefore, the Chevrolet Cruze automatic transmission, with untimely maintenance and insufficient attention to the technical condition, reveals signs of the need for urgent repairs:

ATTENTION! Found a completely simple way to reduce fuel consumption! Don't believe me? An auto mechanic with 15 years of experience also did not believe until he tried it. And now he saves 35,000 rubles a year on gasoline! Read more"

Lubrication leakage associated not only with the loss of tightness of the seals, but also with the overflow of oil into the crankcase.
Increased metal rustling or whistling associated with mechanical development of the mechanism due to exceeding the working loads and operating modes.
Throwing out (knocking out) the engaged gear, having several reasons for the failure of the automatic. So the disappearance of higher gears in turn indicates the degree of overheating of the unit.
A characteristic jerk or jolt when engaging reverse gear indicates a problem in the transfer shaft assembly.
The jerking of the car, regardless of the operating mode, requires immediate diagnosis, because the reason may be in mechanics and electronics. It should be borne in mind that the occurrence of shocks and twitching during acceleration indicates a critical development in the unit and a delay in repairs may not be enough to replace the solenoids and seals.

According to the owners of the Chevrolet Cruze, the automatic transmission of all modifications has the most vulnerable spot - it is overheating, which occurs not only due to untimely or unprofessional maintenance, but because of the design features and driving style at speeds above 110 km / h.

The Chevrolet Cruze automatic gearbox is legendary about the possibilities and economic feasibility of do-it-yourself repairs. some car owners argue that everything is real, while others - that a professional approach is indispensable.

So that everyone can make an independent initial conclusion, it is worth considering that for any level of work, high professional training of a repairman, a large number of specialized tools and equipment is required, therefore, initial impressions of the ease of bulkhead rejection and replacement of parts often end in disappointment with the purchase of a new assembly unit. ...Another reason to buy a new Chevrolet Cruze automatic transmission is the failure of the control unit, the cost of which as a spare part practically reaches the level of the assembly.And to add confidence in the feasibility, it is enough to think that the control unit usually fails only under critical operating conditions, which unambiguously lead to intensive development of the entire mechanism.

Self-repair of the automatic transmission is possible only in case of primary (periodic) malfunctions, when the breakdown did not take on an avalanche-like character, and a high level of preparation in the repair of similar units is required, since ignorance of the specifics of the unit repair leads only to "symptomatic treatment" with a final "lethal" outcome.

Garage repair level (do it yourself):

Control, topping up or oil change, which can be carried out as without dismantling. and dismantling the automatic transmission. When changing the oil completely, it is recommended to replace the filter.
Modernization of the cooling system with the connection of a separate radiator, and professionalism is also required, since it is necessary not only to correctly include the cooling element in the smear system, but also to optimally correctly guide and fix the tubes in the engine compartment.
Replacing oil seals, seals, solenoids, and bearing bushings will require the maximum "garage" level and careful preparation of the workplace. After all, you will need not only special tools (including measuring ones), but also careful control of the absence of even minimal mechanical impurities (debris) from entering the crankcase of the unit, which will disrupt the lubrication regime and lead to accelerated production.

Modern technology has a completely new level of performance, therefore, even with a higher technical education and long experience as a mechanic, there simply cannot be 100% confidence in the success of an automatic transmission repair with your own hands.

And taking into account the time spent and the need to purchase specialized tools, equipment, contacting professionals at the service station, especially when it is necessary to carry out major repairs, is not only relevant, but economically profitable. So, what the repair of professionals can “pour out” into:

For current repairs or modernization of the cooling system, excluding spare parts, you will have to pay at least 5,000 rubles.

Repairs associated with the dismantling of the unit - the price only for work is from 12 to 16 thousand rubles.

For replacing an automatic transmission at a service station, they can request from 8,000 rubles.

Overhaul of the automatic transmission, excluding auto parts, will cost from 12,000 rubles + for dismantling / assembling the box, they will definitely take in the region of 8,000 rubles.

As a result, for a high-quality repair of the Chevrolet Cruze automatic gearbox, you will have to pay from 20,000 to 30,000 rubles, and taking into account the purchase of spare parts, the total cost of the event reaches 40-60 thousand rubles. An exception is the need to replace the electronic unit, the separate replacement of which is extremely rarely cost-effective. Image - Automatic transmission chevrolet cruz do-it-yourself repair

When using a Chevrolet Cruze, the automatic gearbox is heavily stressed. This becomes the reason for the failure of this device. Recently, manufacturers have been producing quite reliable and protected automatic transmissions, which made it possible to reduce the number of breakdowns. However, malfunctions are still present. As a result of movement, the main load in the automatic transmission falls on the valve body. This is the main unit of the automatic transmission. This element is called a hydraulic valve plate.

Our service center is engaged in the professional repair of cars of various brands. We also specialize in the repair of Chevrolet Cruze. The most frequent breakdowns include malfunctions associated with the automatic transmission and its valve body.

When contacting our workshop, mechanics provide the following services:

car diagnostics, during which malfunctions and causes of breakdown are identified;
repair of automatic transmission Cruze;
replacement of the valve body of this device;
replacement of the automatic box;
removal of dirt and traces of corrosion from the part being repaired;
replacement of additional damaged parts.

To determine the breakdown of the automatic transmission or the valve body of the gearbox, you should pay attention to the signs that have arisen. And you can find out the cause of the breakdown only in the service after passing the diagnostics.

An automatic gearbox fails for the following reasons:

Lever wings. In old versions of automatic transmissions, which have a mechanical connection between the selector and the transmission, the automatic transmission lever wings are regularly damaged. This leads to the impossibility of switching transmission operating modes.
Engine oil is leaking. Oil leakage problem is one of the main causes of transmission failure. Leakage occurs from under the seals.
Control block. This device can choose the wrong speed, or block the operation, due to which the automatic transmission is malfunctioning.
Faults with the valve body.

A malfunction of the gearbox may be associated with a breakdown of the valve body. This equipment breaks down due to improper operation of the automatic transmission. For example, starting to travel by car without first warming up the car in the winter. In addition, the faulty operation of the gearbox element may be associated with the cooling system. A malfunction in the functioning of this system is associated with the update of the coolant with the admission of errors.

Chevrolet Cruze owners are able to independently pay attention to a damaged gearbox. To do this, you need to pay attention to the following signs:

the occurrence of jolts when changing gears;
inability to switch gearbox;
blocking the device in one of the gears;
an automatic transmission breakdown error is displayed on the dashboard;
visual inspection shows oil stains on the box body.

In the automatic transmission, the valve body may not work properly. Its breakdown is characterized by the following symptoms:

increased vibrations when changing gears;
grinding noise when switching;
complete stop of the operation of the power unit when changing the selector from the Parking position to Drive;
the occurrence of jolts, bumps and slippage.

The driver himself can only assume a malfunction in the automatic transmission. And when contacting a service center with the help of special equipment, mechanics will establish the exact malfunction. Therefore, you should contact our workshop for repairs. Mechanics carry out repair work on the automatic transmission and valve body quickly and efficiently. Valve body repair Chevrolet Cruze and automatic transmission as a whole:

Selection of original spare parts for automatic transmission Chevrolet Cruze

With a professional approach, the craftsmen take into account the gearbox diagram of the Chevrolet being repaired, attention is paid to the most problematic places in the gearbox of each car. We take only qualified specialists who have been educated and trained on modern equipment. A large list of transmission brands that we deal with allows even young specialists of our company to gain the experience necessary to perform complex repairs. We dare to note that restoring automatic boxes is painstaking work that requires patience. And that is why the specificity of work is a guarantee of quality - in the field of aggregate repair, the work of only conscientious specialists pays off.

We work seven days a week and accept cars even in the most deplorable condition. The cost of repairing boxes for Chevrolet Cruze is fixed; the price of automatic transmission spare parts is indicated in the price list, which we provide upon request.

You can sign up for a Technical Service Station by calling our phone number, which is common for all divisions. 8 (495) 637-82-39. Be sure to call! We will advise you on all your questions.

Gearbox maintenance is a planned list of work to replace consumables (automatic transmission filters and transmission fluid). If necessary, minor "repairs" are performed - a set of solenoids, a brake band, oil seals and gaskets are replaced, a set of clutches and discs, and so on. They also carry out a control check of the gearshift modes, which is included in the diagnostics of the automatic transmission.

But the most important role in the course of maintenance is played by working with automatic transmission oil, since the rate of wear of the system decreases with high-quality oil. If the oil becomes cloudy, then we will talk about a partial oil change. But if the liquid has darkened, but is still transparent, then you should not change it ahead of time. A complete replacement of ATF is carried out in accordance with the manufacturer's regulations, while it is necessary to remove the pallet.

It is important to measure at the end of the work oil level in automatic transmission Chevrolet Cruze, since underfilling the liquid threatens to disrupt the pressure in the lines and air the system. In the technical center, when performing this service, by default, they take into account the peculiarities of checking the oil level for the Chevrolet Cruze gearbox, both "cold" and "hot".

Before pouring in a new one oil in the box automatic Chevrolet Cruze, you need to decide on his choice. Our specialist will help you with this, who will select the right option for the automatic transmission. At the same time, it is important to focus not on reviews of automatic transmission oils, but on the manufacturer's recommendations.

If the owner has been operating a faulty automatic transmission for a long time, then the level of malfunctions reaches a critical one. And since it is too expensive to replace all the components, it is cheaper to install a new gearbox.

Deciding what is required replacement of automatic transmission Chevrolet Cruze, is accepted if it is required to re-install more than half of the components of the box. In this case, replacing the automatic transmission can be cheaper than restoring.

Buy automatic transmission Chevrolet Cruze you can through us. Choosing a used gearbox for Chevrolet will be several times cheaper. However, it is impossible to guarantee that the Chevrolet Cruze with such a transmission will work for a long time.

We place an emphasis on new contract units, we offer options only after thorough tests for proper operation and, of course, without a guarantee. And even in this case, we still focus on remanufactured units, that is, removed, checked and received from a reputable supplier. The warranty only applies to contract units.

Please note that the information provided below is for informational purposes only. We will try to outline for you the main points in our approach to repairing automatic transmissions of a specific car model - Chevrolet Cruze.

In most cases, the automatic transmission can be repaired, with the exception of the car's gearbox burned out (in this situation, it is necessary to replace the unit). You need to understand that there are parts that can be replaced, and if the elements cannot be restored. This is what you should rely on when calculating the cost of repair measures.

The main malfunctions inherent in the Chevrolet Cruze transmission make the following services popular:

Attention should also be paid to the oil pump, the failure of which is associated with operation with a broken bushing or dirty oil. Leaking oil seals are generally one of the typical indications of the need for repair.
A relatively limited service life is characteristic of the valve body and solenoids, whose functionality is gradually deteriorating in proportion to the wear of the clutches. A clogged valve body is one of the main causes of a breakdown, diagnosed on a computer.
Often it is required to repair the torque converter, popularly called a bagel. It will need to be sorted out in order to restore operability, along the way clearing it of metal shavings and dirt.
The basic task is to replace repair kits (Overol Kit or Master Kit), change clutch kits, steel discs, install new pistons, bushings, and other components.
The filter and pan gasket are often replaced.

In addition to replacing parts, welding is characteristic of automatic transmission repair. So, you will need to work with argon during the repair of the torque converter or if the gearbox housing is cracked.

We offer the following complexes of repair and restoration work:

Replacing a broken automatic gearbox with a new or refurbished one.
Partial repair of automatic transmission.
Overhaul of the transmission.

You can apply for an initial consultation by phone if you are interested in full technical information, and drive up to the repair or maintenance of the automatic transmission by agreement. If your goal is do-it-yourself repairs, then we can provide information on the availability of suitable spare parts. Otherwise, we advise you to visit any specialized forum on Chevrolet.

Which automatic transmission is installed on your Chevrolet Cruze is indicated on a plate located on the body or on the automatic transmission itself. By designating these data to our manager when you call, you will be able to receive accurate information on the availability of spare parts and the selection of analogues.

How much the parts cost is a matter of the original manufacturer's prices, each has its own. The only thing that is the same for an automatic transmission of absolutely any foreign car is that the planetary group is the most expensive element. As for the prices for the installation of new elements on the Chevrolet Cruze, we provide the price list upon customer request.

For automatic transmission repair, a mandatory one is characteristic. We will help you to select all these details according to the design of the Chevrolet Cruze automatic transmission of a particular year of manufacture.

We always have a complete set of gearbox repair kits in stock, which you can buy:

Bushing Kit - a set of bushings.
Bearing Kit - a set of thrust rolling bearings.
Banner Kit - gaskets and friction discs, o-rings, oil seals.
Washer Kit - a set of thrust plain bearings.
Sealing Ring Kit - a set of o-rings.
Repair Kit - a set of elements for the repair of a single unit.
Overhaol Kit - Gaskets, oil seals and o-rings.
Master Kit - gaskets and friction / steel discs, o-rings.
Gasket Kit - all gaskets.
Filter Kit - filter and pan gasket.

By default, we offer original OEM parts from the manufacturer, however, if the client wishes, our specialist will advise which analogs are suitable for solving the problem. We are trying to expand the list of quality, but cheap parts.

In fact, for each automatic transmission, a separate list of running parts has been formed, which do not need to be looked for separately - you can immediately select a running solution. And we find unique elements for the selected modification on request. Thus, for the Chevrolet Cruze automatic transmission, you can buy repair kits and elements of any type from us.

If the box slips, kicks (pushes), does not switch, makes noise, jams or even leaks, then it is up to diagnostics. It can be computerized or mechanical.

During the automatic transmission diagnostics, error codes are read on the computer, which must be correctly deciphered. The difficulty lies in the fact that they differ from manufacturers, so that you cannot do without knowledge of the list of designation of malfunctions for Chevrolet cars.

During the assessment of the condition of the transmission, the technician pays attention to the faults that can be heard and seen. The auditory version of the diagnosis is the fastest, the visual and mechanical one is more difficult.

Removal of errors and inspection indiscriminately of the gearbox give a superficial view. So, we can assume that it is necessary to check the ECU and electrical circuits of the gearbox, clean the sensors from oil, and so on. The main type of automatic transmission diagnostics requires analysis. Subsequently, according to the data received, a defect list is drawn up and repairs are performed without removing the transmission or with removal.

It's great if you can formulate the main symptoms of a malfunction by calling our manager. Additional information on the type of automatic transmission (code) will help to immediately calculate the cost of a possible repair based on the availability of spare parts.

How to pre-check the automatic transmission? List of indirect signs of defects:

Gear shifting problem: long interval or slippage at increasing rpm.
Automatic transmission oil flows, getting on the joints of the box or into the engine.
Oil color: almost black brown oil, there is an emulsion in the liquid, there are bubbles (signs of foaming) or black bloom on the dipstick. One of the above is enough to come for inspection and maintenance.
Strong burning smell (clutches or "iron" burned out).
Noise in the gearbox, bumps, jerks.

Automatic transmission is installed on Chevrolet Cruze cars 6T30 and 6T40... Their advantage over other units is fuel economy, switching speed, adaptability. But we also have a number of childhood diseases and design features. The box allows you to "kick" and in acceptable manifestations this is normal. The 6T series itself has established itself as an automatic machine of average reliability (in comparison with other automatic transmissions). Already by 100,000 km, routine maintenance is often required, with the replacement of consumables. Often already at 60-80 thousand km. the mechatronics (the brain of the box) is changing. During our long practice, we have studied all the diseases of this family and we can safely say that there are no insoluble problems for us regarding this series. If you need really high quality automatic transmission repair Chevrolet Cruze - call us, we will definitely help.

It is also worth paying attention to the oil. Many car owners on forums and blogs have already come to the conclusion that ATF at the factory does not add to these automatic transmissions (about 0.5-1 liters). We advise you to check the level of each MOT. The box does not often give errors, this concerns the valve body, incorrect working of the valves, the owner may notice slight jolts (hot). If slippage occurs, then with a high probability it can be said that the clutch pack in the box has burned out, but this is only a consequence, but the initial problem is often hidden in mechatronics, which transmits incorrect parameters, or in the valve body (much less often). Do not delay the diagnosis - only qualified specialists will be able to accurately identify the malfunction already at this stage.

Examples of our work on the repair of a Chevrolet automatic transmission

Hello! We would like to tell you about one of the most typical automatic transmission repairs, namely a 6T30 gearbox, a car Chevrolet Cruze.

The car came to us on its own, but as is often the case with sores, namely:

- kicks from 2-3
-slipping 3rd and 5th gear.

Plus another symptom was a hard hit on "R"

Let's first tell you a bit about this gearbox: the 6-speed automatic transmission family from GM 6T30E “Hydra-Matic” is a modern family of the generation of front-wheel drive transmissions, which has been installed since 07 on cars of such brands as Chevrolet, Buick, more often of course it was installed on Opel Astra, Saab , and of course Cruz, and Aveo.

As is usually the case, we removed the automatic transmission, and carried out a troubleshooting, the malfunction turned out to be typical for this type of automatic transmission, namely the problem of the 3-5-R clutch, this is a “childhood disease” of these automatic transmissions with which we know how to fight.

A set of gaskets also fell under the replacement, and spare parts necessary for repairing, only if all consumables are replaced, you can be sure of repairing your automatic transmission.

At the end of the repair, we gave the car to a satisfied client and he left the walls of our service with a guarantee for the work done!

If you don’t like something about the operation of your automatic transmission, or, on the contrary, you want to be convinced of its excellent condition, then come to us for free diagnostics, and be confident in the condition of your units!

Greetings, our dear readers, this week we have as many as 2 Cruises with essentially the same problems.

The essence of this problem with this 6-speed automatic transmission made by GM is a childhood illness, namely, when peak torque loads are reached, a wavy spring bursts, it is also a “Belleville spring”. As a result of such a breakdown, the entire clutch package begins to dangle and often leads to the failure of the sun gear sleeve. Also, among the malfunctions, a broken chain damper was noticed, also known as plastic diff protection.

As a result, the following fell under the replacement:

Gasket set;
-Drum 3-5-R (wear);
-Spring disc;
-Oil and filter.

I also had to perform the maintenance of the torque converter in order not to return to the automatic transmission repair any more, and to carry out all the adaptations, including setting the level and oil expiration date through electronic diagnostics.

Clients received a 1.5 year warranty for the work performed

The client came to the diagnostics and complained that the gearbox seemed to "jam", go into "tightness" and it worked better in the low gear mode.

We carried out electronic diagnostics which showed that there was an error in the 5th gear, namely
– P0735 (5th gear incorrectly adjusted)
And an error on the gearbox control unit P0700 (transmission control system, malfunction).

Troubleshooting showed burnt out friction discs, brake band, brake drum, pump and control unit AW55-51.

We carried out a major overhaul of this box, and the owner received a 1.5 year warranty for the repaired unit!

The car came to us with an error in the TCM (Transmission Management) system and we almost immediately started troubleshooting the box.

( 6t30 - 6-speed automatic transmission family from GM 6T30E “Hydra-Matic” - a modern family of front-wheel drive transmissions generation, which has been installed since 07 on cars of such brands as Chevrolet, Buick, more often of course installed on Opel Astra, Saab, and of course Cruz, and Aveo .)

After troubleshooting, we found a standard sore for this gearbox (6T30), namely a faulty 3-5-R clutch. This happens due to the fact that the spring disk often does not withstand sudden starts and accelerations and simply bursts when the peak torque is reached.

As a result, the entire clutch package begins to "dangle" and leads to the failure of the sun gear sleeve, and malfunctions of the drum itself.

Also in this case, the chain damper (plastic protection) has become unusable.

The amount of refurbishment of this box was 88 thousand rubles, for this money the client received essentially a new automatic transmission with a guarantee 1.5 years!

One of the few examples when the 6T40 series automatic transmission is killed to such a state. Chevy Orlando car, 2012 onwards, with mileage of 214.000 km. This is already a pretty good indicator.

Even with this mileage, the symptoms were very "modest" - this Chevrolet Orlando disappeared (R) back, dismantled and wondered how the car generally moved under its own power!

Completely burnt out steel discs, which have changed their structure and geometry. Broken spring disc, plastic protection. And even a "sun gear".

Video (click to play).

The replacement included: Pistons, spring discs, retainers, planetary gear, freewheel, bushing kit, 3-5-R drum, sun gear, almost everything that had to be replaced, the photo shows the extent of the damage .. do not bring the car to this! Surprisingly, the valve body as a whole left a good impression, and in order to save the client's money, it was decided to leave it.
