DIY CVT repair

CVTs are gaining more and more popularity among the varieties of gearboxes. So the carmaker Audi did not stand aside and installed variator gearboxes on the new A6 C6 models.

Each of the above listed elements can fail at any time. In today's article, we will analyze with you the main malfunctions of the Audi A6 variator, their causes of failure and methods of self-repair.

Earlier I already told you about how to replace the fuel filter Audi A6 with your own hands, so anyone interested can read this article by clicking on the link.

Most of the malfunctions in a CVT gearbox arise from improper operation, which I would refer to:

• Violation of the frequency of replacement of the working fluid
• Violation of the frequency of filter replacement
• Using poor quality fluid
• Aggressive driving style

In addition, there are other malfunctions that are determined using computer diagnostics. Each malfunction has its own diagnostic code. The codes determine:

• malfunctions of input sensors (working fluid temperature sensor, speed sensors of the driving and driven pulleys, pressure sensors in the main line, pressure in the driving and driven pulleys);
• malfunctions of the electronic control unit;
• malfunctions of actuators (stepper motor, solenoid valves of pressure in the main line and pressure in the driven pulley, lock-up valves of the torque converter and control of the planetary gearbox).

The most common cause of variator malfunction begins with wear on the bearings of the cones, while a characteristic hum becomes audible. Bearing noise occurs due to the ingress of wear products on their working surfaces, as a result of which they become unusable. Special oil filters retain metal suspension for the time being.

The next reason that can cause problems with the variator is jerking and jerking of the vehicle, which occurs due to the seizure of the oil pump pressure relief valve. The same harmful wear products interfere with the normal operation of this unit, disrupting the stable pressure in the system.

Timely contacting a specialized workshop will help to avoid higher repair costs. Minor damage to tapered pulleys is removed by grinding, while the belt will most likely have to be replaced.

The rather rare malfunctions that precede the breakdown of the variator include the failure of the torque converter, as well as failures in the electronics caused by breakdowns of some elements of the control unit. However, this kind of malfunction occurs quite rarely and is not a regularity, but rather a factor of bad luck.

As I already noticed earlier, the most common variator failure is considered to be worn out bearings for cones. A sign of this problem is a prolonged hum, which manifests itself already when driving 50 thousand km. To change all bearings and their parts, the motorist will have to pay over 34,000 rubles. Such a malfunction most often occurs in Audi A6 C5 cars.

Loud noise of bearings, and then their slow destruction occur for the following reasons. First, the destruction of the working surfaces is facilitated by the ingress of various foreign metal bodies, such as wear products, on them.

The installed oil filter and magnet collecting metal powder cannot block access to the working surfaces of the variator for heavy foreign bodies.In this case, the bearing life will extend the reduction of the engine oil change time to 25 thousand km.

But that doesn't always help. There are cases when some CVTs work quietly for 100 thousand km, while others, under the same operating conditions, buzz even when driving 50 thousand km. High bearing noise is often caused by poor quality bearings, low accuracy and low load ratings.

When it comes to shortening oil change intervals, not all manufacturers share the same point of view. For example. During the warranty period (100 thousand km), Renault advises only to carry out periodic checks of the oil level and condition. At the Audi concern, the oil change must be done once every 75 thousand km.

In addition to the usual machine oil, it makes sense to fill the variators with special oils marked “CVT”, original NS-2 or ELFMATIC CVT fluids. For Audi cars, DiaQueen type CVT-J1 can be used. It is not recommended to pour the oil used in the hydromechanical automatic into the variator, although some little-known manufacturers have adapted their variators for these substances.

Often, when the vehicle is moving, jerks and twitching appear. Reason - the pressure relief valve in the oil pump does not work.

Wear products falling on the contact surface wedge it in an intermediate state. As a result, the pressure level deviates from the norm, which impedes the operation of both pulleys and causes the belt to slip. In this situation, you need to make a visit to the service center as soon as possible.

With timely treatment, repair work will be cheaper: small defects in tapered surfaces are eliminated by grinding.

During diagnostics, specialists often consider problems with the front wheel bearings to be the cause of the noise of the variators, which are immediately replaced with new ones. Replacing these bearings can be costly, since on some machines it is one piece together with the hub, which costs between $ 300 and $ 400.

Many motorists who pull out a stalled vehicle by jogging by quickly moving the lever from position D to R and vice versa, are faced with the following situation - jerks when moving the lever from the parking position to R and D. with friction wheel. The wear of the splines is explained by the absence of a pause when moving from D to R and vice versa (you need to wait for the vehicle to stop). As a result, the gears of the planetary gear must be replaced.

Some drivers, when this problem occurs, immediately begin to check the valve body for malfunctions, which is actually reliable and problems with it rarely happen.

A lot of attention in a stepless unit is paid to the temperature regime. Often, problems in the operation of variators arise from an increase in temperature. In modern cars, a self-diagnosis device is provided, which includes special sensors. When the temperature value rises, they turn on the indicator on the dashboard indicating a malfunction, and the variator is put into emergency stop mode.

To maintain the normal temperature of oils in modern cars, in addition to a heat exchanger, another radiator is installed in the engine compartment near the climate system. Various dirt gets into the bumper through the air duct.

The first sign of a dirty radiator is overheating when the vehicle is moving at high speed. Therefore, once every 3 years (or more often) it is necessary to thoroughly flush the radiator. It would also be nice to install a special mesh in the air duct to protect the radiator from various objects flying out from under the wheels of the car in front.

Despite the mistrust of domestic motorists towards CVTs, Western motorists install this type of transmission with a greater degree of optimism. According to statistics, they break down much less often compared to hydromechanical gearboxes. That is why many car manufacturers, who initially doubted the durability of CVTs, are now being installed more and more every year.

For example, the manufacturer Audi installs variators on a new generation of crossovers with a two-liter engine. Subaru has CVTs for XV, Forester cars. By the way, most of the users of these cars cannot be classified as calm motorists.

These machines are used for high speed cross-country travel. But before, many thought that the variators in such conditions would immediately fail. This means they have become better quality.

Cars with CVT transmissions have recently become more popular among our compatriots. This type of gearbox is relatively new, so not every motorist knows about the device and the benefits of using such a unit. What is the Audi A4 variator, what are its design features and disadvantages, we will tell you in this article.

The first manufacturers to equip their vehicles with variable speed transmissions (CVTs) were Volkswagen and Audi. The company equips the Audi A4 and A6 models with Multitronic transmissions. This type of gearbox belongs to continuously variable transmissions. The consumer characteristics of the Multitronic are quite high. The model of the check point "01J" is installed in A4 and A6 cars.

Gearbox CVT Multitronics 01J

If we talk about the design, then the main constituent elements of CVTs on Audi are as follows:

Before buying a car with a CVT, many motorists are interested in the question of how much the CVT travels on average. The service life in vehicles Audi 2012 or other model year may be different. It happens that the box serves 40 thousand km, and sometimes it fulfills 200 thousand kilometers without any complaints. It all depends on the conditions of use and maintenance of the machine. Precisely because CVTs are very sensitive to misuse, many potential car owners bypass cars with a CVT side.

You can repair the CVT transmission from an authorized dealer or service station. Service from "officials" is relevant if the vehicle is still under warranty. The cost of repairs at a dealer is higher than at specialized service stations.

A common type of CVT breakdown is the failure of the electronic unit. You can try to fix the problem by flashing the device, but the dealer usually changes the ECU. Car owners are faced with the problem of breaking a metal chain. "Officials" in such cases change the entire gearbox assembly.

Carrying out computer diagnostics of the CVT transmission, you can get error codes that indicate the following problems:

• 17105 P0721 or 17106 P0722 - the output speed sensor has broken down, this leads to the absence or supply of an incorrect signal from the control device;
• 17114 P0730 - diagnostics show an incorrect ECU gear ratio;
• 17134 P0750 - the ABS / EDS unit is broken or does not work correctly;
• 17137 P0753 - problems in the operation of the transmission electrical circuit;
• 18201 P1793 or 18206 P1798 - the sensor for the number of output revolutions has broken down or is not functioning correctly, with such a problem the signal from the controller will be either incorrect or completely absent;
• 17090 P0706 - the transmission selector position sensor is out of order or not adjusted.

Why the emergency mode of the variator turns on and how to solve the problem - find out from the car owner's review on the video (the material was filmed and published by the Cars and Upgrade channel).

In emergency mode, the variator gearbox works when problems appear in the operation of the control unit, electrical circuit failure.If this mode is activated, the PRND scale on the dashboard will immediately light up. Other signs of malfunction:

• the driver presses the gas pedal, the car starts jerking;
• when switching speeds, the car jerks;
• in some cases, it is not possible to activate the reverse speed;
• when the gearbox goes into emergency mode, the car cannot be removed from the parking mode.

Mechanical faults include:

• damage to electrical wiring, open circuit;
• oxidation or damage to contacts on sensors or control unit;
• open metal circuit CVT;
• mechanical damage to controllers;
• failure of the control unit as a result of mechanical impact on it, in this case, flashing the device will not help.

An example of what failures can occur in the operation of a variator transmission is shown in the video (the material was filmed and published by the user Ilya Filyaev).

Replacing consumables begins with the purchase of an original oil.

For use in Audi CVT gearboxes, General Motors has released a special lubricant called ATF AUDI G052180A2.

If you are having difficulty finding an original oil, then you can replace it with Mobil1 LT71141. This liquid is no worse in quality, but its cost is on average 50% less. The oil should be changed every 60 thousand km. With such a run, the liquid usually loses its properties. In principle, you can use any other oil, as long as it meets API or SAE standards. When buying a lubricant, purchase:

• filtering device;
• sealant;
• rubber gasket for the pallet.

The volume of the purchased oil canister should be 5 liters.

As for the filters, there are two of them in CVT transmissions. One of them is mounted directly in the unit itself, therefore, to replace it, you will need to disassemble the unit. The second filter is the part of the tube connected to the radiator. This tube is only replaced if it becomes clogged or foreign particles are found in the lubricant.

In addition to the filter and the liquid itself, prepare:

• socket wrench -3357;
• hexagon;
• construction or medical syringe for filling with a special tube;
• clean rags.

Below is a detailed video instruction for self-changing the working fluid in a CVT gearbox (video filmed and published by the Artur Prokurov channel).

It is necessary to change the lubricant in a garage with a pit or on an overpass, if possible, use a lift. The vehicle must be positioned horizontally and secured. The replacement process is performed like this:

Let's try to figure it out by evaluating the pros and cons of each type of transmission.

1. Reliability of the device compared to CVT. Even if you violate the rules of operation, you are unlikely to be able to burn the clutch. In automatic transmissions, this function is performed by a torque converter, which is in principle more reliable.
2. Automatic transmissions wear less vehicle engine. The automatic transmission independently performs gear shifting, while not spinning the engine crankshaft to maximum speed. And this has a positive effect on its service life.

Now let's consider the disadvantages of "automatic machines":

1. Low dynamics. Cars with automatic transmission cannot show the dynamism that cars with a CVT demonstrate. Because of this, when overtaking a vehicle with an automatic transmission, it takes more time to maneuver. In this case, mechanical transmissions are inferior to variators.
2. Increased fuel consumption. Engines with automatic transmissions consume an order of magnitude more gasoline than the same car models with CVT or "mechanics". On average, the difference in consumption varies in the region of 1-2 liters per 100 km of run.
3. Automatic transmissions usually require more oil when changing fluid. For example, “automatic machines” need about 8-10 liters of consumables, while 5-6 liters are usually poured into variators.In addition, in automatic transmissions, the oil must be changed more frequently.

Below is a detailed video review of CVT and automatic transmissions. The author of the video talks in detail about which gearboxes are better and more reliable (the video was filmed and published by the Avto-Blogger channel).

1. Good car dynamics. A vehicle can accelerate an order of magnitude faster than a car with an automatic transmission.
2. Driving a vehicle with a CVT is generally smoother. Due to the lack of gears, there are no jerks when shifting them.
3. Profitability. CVT cars generally use less fuel than automatic cars.
4. Possibility of driving a vehicle both in automatic mode and in manual mode. If the driver gets tired of the automatic transmission, he can switch to manual control and independently change gears in accordance with his needs.

1. The reliability of the CVT is poor. If you are wondering if the variator is reliable, then as we said, this type of gearbox often fails. Moreover, it can break even after 40 thousand kilometers. The weak point of CVT gearboxes is the control unit.
2. A sophisticated and expensive service. CVT transmissions are not as widely used as automatic transmissions. Accordingly, they are not yet well understood by specialists at service stations. Therefore, only authorized dealers are usually engaged in the repair of such gearboxes.
3. One of the weak points of the variator is the chain. As a rule, its resource is about 100-150 thousand kilometers. But it happens that it wears out earlier. And its replacement is not a cheap pleasure.
4. CVT gearboxes require special lubrication. Moreover, for each car model with a CVT, a specific oil must be used. The cost of consumables is rather big, and it is impossible to use unsuitable liquids.

Detailed and visual instructions for disassembling a variator transmission are given below (the video was filmed and published by the Ambulance channel for your unit).

Variable speed drive 01J (CVT 0AN Multitronic or VL-300) released by Audi in collaboration with LuK GmbH & Co in 2002 for the popular all-wheel drive models A4, A6 and A8. With engines from 1.8 to 3 liters. Transmits up to 310 Nm of torque.

Audi made many names for different sub-modifications for each variant of the car and engine, modeled on the names of Honda's automatic transmissions, but these are all Multitronic variators with different letters of the FSA type. JFJ from 2000 to 2007 (below is a table) have the same design for hardware and electronics and are repaired with the same Repair Kits.

Pick up repair kits - press the button on the left.

Typical diseases of the 01J variator:

The main reason for coming to repair this fairly reliable variator in the early years is the oil change (G 052 180 A2).

A partial oil change requires approx. 4.5 liters. Complete replacement - by double partial replacement - 7.5 l. It is sensitive to the level and quality of the oil, the oil is checked against the overflow plug - at a temperature of +35 .. + 45 ° C, oil should start to flow. Change is recommended in 40-60 tkm, but the older the variator, the more often it needs to be checked and changed. Opaque oil is a marker for urgent oil change or overhaul.

Filters are available with 130010 tube (Original) and without 130010A tube (non-original). There are two types of the filter itself - with a rib (130010A - 01J-301-519N) and without rib (130010B - 01J-301-519L ). Interchangeable. The filter is inside the box and changes only when the variator is overhauled.

The design of the 01J variator is especially demanding on the purity of the oil and operation with a borderline state of oil and with a clogged filter kills the variator units with every kilometer of run.

A typical overhaul order for this variator is Gaskets and Seals Repair Kit # 130002. More often they order budgetary Overol ATOK-130002A less often - Prescription.

Rings, seals and seals are changing, aging rapidly from high temperatures.

In some repair kits, there are no Reluctors - speed indicators.They (Regulators, on the right in the diagram - yellow) sold separately - No. 130079, when the craftsmen find it necessary to replace them as well.

Also, clutches are often ordered in one Set - No. 130003.

Kits differ in the thickness of the Forward clutches. 2.7 mm (unified with 0AW) or 2.05 mm.

Winter driving with a cold transmission kills the friction clutches especially quickly. More details - here.

Also, only in a set (Forward and Reverse) order a set of steel discs. - No. 130004.

The kit also changes the piston Reverse 130966 during the bulkhead.

The next typical CVT consumable 01J : Ejection pump (No. 130501).

The ejection pump is made of plastic and works according to the principle of "atomizer", when one stream of liquid entrains (the other) a stream of air. Only in this variator, instead of air, another stream of the same oil is carried away by oil. And of course, like all atomizers, such a system is demanding on the cleanliness of the channels and the oil temperature. It is quickly clogged with suspension, the channels wear out, ceases to work normally and together with the rest of the “consumables” must be replaced.

Problems with this pump lead to problems with the cooling and lubrication of the clutches. He really does not like working with cold oil.

Another consumable is the oil pipe (No. 130992).

All three solenoids-electric regulator are changed after the resource is exhausted (normal resistance is 4.7 Ohm).

Solenoids are the same: 130420A - no spout, there are three solenoids on the plate: N88 - cooling and emergency shutdown solenoid, N215 - pressure regulator in clutch packs, N216 - pulley gear ratio control solenoid (see diagram on the left)

This variator uses a pull chain. From tensile loads and friction, such a chain develops its resource quite early (Drive chain variator - No. 130700), is replaced practically at every overhaul of the variator after runs over 100 tkm, since even a slight wear will lead to a noticeable disruption in the sliding of the chain along the cones, which immediately reduces the transmitted torque and quickly "ages" the cones themselves.

Empirically, a regularity was established that up to 2 liters it is reasonable to use a pushing chain, and over 2.5 liters - a pulling chain. But for powerful cars, the variator turns out to be even less reliable than preselective boxes, and in modern stepped automatic transmissions, the gearshifts have become no less smooth than in variators, with a significant superiority in reliability. Therefore, the direction of development of variators in the direction of the "pulling" chain can be considered unpromising.

Together with the chain, tension bars are often changed - 130701 and 130702.

The design of the variator does not allow the vehicle to be towed, which leads to fatal consequences for the cones and, as a result, for the transmission itself. The cone is the CVT unit that determines the resource and the bottleneck in the design.

The sore spot of an electrician is familiar to all variators and 6-mortars of the first generations: ECU - CVT control unit Multitronic VL-300 ... For repair press No. 130446A.

The reason for the early failure: the unit floats completely in oil, which heats up in these transmissions over 110 degrees. The material of the case and sensor components, especially of the first years of production, could not withstand prolonged overheating.

Therefore, for these variators, there is a recommendation after 3-5 years of operation - to install an additional oil cooling radiator. Or every summer to clean the existing cooling system inside and outside and change the oil more often than at a “young” age.

In 2003, the manufacturer refined the design of the control unit, using materials that are more resistant to temperatures and the VL300-7 Multitronics began to come for repairs later and less often.

The problem is usually expressed in the fact that the display "PRND" lights up and the computer gives various kinds of errors. And depending on these DTCs, the Multitronics are successfully repaired. (Suggestion from below).

- There is another serious (but more rare) problem - Differential.

During the overhaul, you should pay attention to the condition of the differential. If there are problems with him, then the box is not a tenant. Differential replacement 01J it is almost impossible work in a service environment.

Fighting Oil Leaks - Replacing Oil Seals:

- cuff (oil seal) of the pump (130070),

- cuff of the left and right axle shaft (130073, 130076).

The opinion of the masters on Multitronics is here and here. 01J device - here.

In general, on new cars this super-complicated and finely adjusted transmission works fine in German, but after 150-200 tkm driving with it is like playing “Russian roulette”.

Refurbished Multitronic VL-300 on ZF variator 01J.

Two variants of Multitronic are known to be repaired:

- Square connector (on right 130446 B).

- With K round connector (left 130446A).

Although the investment in a proprietary European CVT project was astronomical, this pull-belt CVT design could not compete with DSG and push-belt CVTs. Many designers and financiers consider such a design a dead-end branch of automatic transmission development and an unsuccessful investment of Audi.

The thief works at night It's all clear

Very nice guy, informative.

9:50 he said exactly - I laughed to tears who came up with the design of the beetle😂 that was there and stuck the variator😂😂😂

Nice to watch, the manner of presenting information is lively and informative.

The problem is not with the variator, but with the automakers. Why is it worth producing replaceable bushings, pulleys, chains? penny. a complete repair kit, the cost price is no more than 50-70 bucks. On mopeds, the same variators, only a rubber belt and no hydraulics, in 10 minutes everything changes on the knee and again like new.

Loves the head - is that fucking brains?

Stas, you would still show all this under the candle

Stas you are talking about some kind of nonsense about CVTs, especially about Audi, I own an Audi A6 in the back of a C7 2. 0 TFSI 180 hp. With. CVT variator, auto in 2014 Bought It on a run of 35 thousand on 40 thousand made a Revo chip for 260 liters. With. I don’t force the car, but I don’t feel sick, now the mileage is 94 thousand. The variator works great. There were absolutely no problems. I changed the oil in the box by 40 and 80 thousand. Original.

Mechanics-Foreva And about juke is true: On a test drive Mitsu Outlander, he climbed a 40 hill, on a CVT. And it is considered a crossover.

dark och. Like put everything Pts informatively, but there is work to do. good luck

yes the variator is PPC. They would have done it like on mountain, high-speed bicycles, clicked and the chain spilled over to another sprocket xD, and it would have been better

mechanics that's all 100 years will still ride and can be repaired on the knee

Buddy, couldn’t you shoot the video in the light?

It is incorrect to call the variator a box. There are transmissions, various, including: a manual gearbox, an automatic gearbox, a robotic manual transmission and a variator. There are also types of transmissions, but I will not load. Here automatic transmission and manual transmission are boxes. But the VARIATOR IS NOT A BOX Although it is also a transmission. I'm not a bore, Stas, but I urge you to choose the right terms. Express yourself correctly.

Stas or whatever you are. You are still too small to lisp any nonsense about the variator. There is nothing better than the variator. This is the only gearbox that allows the engine to run at its BEST mode most of the time. For all other gearboxes, 75 times the engine runs in NOT the most favorable mode. Humanity has NOT come up with anything better than a CVT. Today, the best CVTs are two-stage with a gear ratio of more than 6 6. 2. Believe me, people in my life I have moved on all types of gearboxes, but there is no better VARIATOR Millions of kilometers and dozens of cars give me the right to insist on this approval. Of course, this is true for light and passenger cars. But progress does not stand still, and since the variator came to the auto industry later than the rest of the boxes, then this suggests that the variator is better than the others, which have already run into their limits, and this variator still has room to grow.

I changed the oil on jatco for 150 thousand, mileage, now 200 and drives.

... can you find out at what mileage the problems started?

The CVT gearbox is gaining more and more these days, and there is a fairly simple explanation for this. First of all, it is the simplicity of the design. But, nevertheless, the service and repair of the variator requires certain knowledge and skills. The gearbox consists of various components and systems, which, if used incorrectly, can malfunction and it will be difficult to repair them.

Many variator malfunctions are the result of non-observance of the basic rules of operation and maintenance:

• non-compliance with the terms of fluid replacement;
• failure to comply with the deadlines for replacing filters;
• the use of low quality lubricants;
• driving errors;
• driving at top speed;
• frequent sharp braking;
• driving on bad roads.

To avoid many troubles with the variator box and then not to repair, adhere to the following simple maintenance rules:

• every thirty thousand km. mileage change the oil;
• change the filter elements in time;
• after seventy thousand km. mileage change the stepper motor and shaft sensors.

Disassembled variator gearbox

Do not forget that diagnostics of the variator is much cheaper than repairing it with your own hands, even at a service station.

In the event of a malfunction concerning the electronic part, the message - Service required will light up on the display located on the dashboard.

Electronic problems

If the temperature of the liquid rises above the norm, it will light up - Slow down.

In order to accurately establish the breakdown and fix it yourself, you need special diagnostics carried out using special equipment. For many breakdowns, a special code is provided by which they are installed:

• sensor malfunctions (temperature, pulley speed, pressure, line, pulley pressure);
• ECU malfunctions;
• malfunctions of a stepper motor, valves, mains;
• decrease or increase in pressure in the pulley.

When carrying out diagnostics, do not forget that a probable prerequisite for a malfunction may not only be a breakdown of some unit. Often, the wiring can be damaged or a defect in a connector. Also, the problem may lie in the failure of the transmission control unit.

In some situations, upon detection of malfunctions, the control system of the variator transmission can be automatically transferred to a special mode. This mode differs from the usual one in a special fixed gear ratio.

It will not be possible to establish malfunctions of the mechanical part of the boxes only with the help of electronic diagnostics. In this situation, there is a need to carry out a whole range of measures:

• it is necessary to check the condition of the working fluid;
• identify all the symptoms of a malfunction;
• analysis of all ECU data;
• testing on the road.

In the operation of variator boxes, failures and breakdowns of a different plan sometimes occur. Very often there are noises and squeaks of various types. In this case, the transmission may need to be disassembled. This process is not so complicated and with a detailed study of the material, you can handle it yourself.

Before proceeding with disassembly, it is worthwhile to prepare in advance special containers for the parts to be removed. To make it easier to assemble later, arrange the containers in the order of disassembly. If you are doing this work for the first time and are not sure that you can remember the order of disassembly, then the whole process can be captured on the camera. Parts can also be labeled.

It is better to repair in a well-lit and ventilated area.

1. The first step is to unscrew the bolts that secure the cover.
2. We remove it.
3. We remove the shaft together with a part of the body.
4. We unscrew the remaining bolts.
5. Remove the second part of the cover.
6. We remove the gears.
7. We unscrew the screws that secure the pump casing.
8. We remove the gear.
9. Remove the pump chain.
10. Remove the oil pump cover.
11. We remove the shaft.
12. We turn over the gearbox.
13. Using a screwdriver, remove another cover.
14. The belt must be tightened with clamps.
15. We remove the pulleys and belt.
16. We release the pulleys from the belt.

Removed and disassembled gearbox

Now that the variator is disassembled, it is necessary to check all its components and systems. Pay special attention to the condition of the bearings, pay attention to whether the backlash is increased. Look at the condition of the belt and if its tension is loose. Inspect gears, hydraulic block and other parts for possible defects. The most common problem resulting in noise in the CVT box is high bearing wear. In this case, nothing will help, except for a replacement, you can do it yourself.

It is very important to identify the malfunction in the variator box in time and eliminate it. This will allow you to avoid more serious damage, which will be quite difficult to repair, and it costs much less.

In this video, the auto repairman will tell you in detail and show how you can repair variator gearboxes with your own hands. It costs much less than contacting a service station.

• Self-flushing of the automatic transmission valve body
• We do the repair of the machine box ourselves
• Compare the tiptronic gearbox and the automatic

In fact, everything is written very correctly. In any case, I try to solve such problems in car services at inexpensive prices, they do their job efficiently.

Hello
I have a problem with the box
honda fit 2002 release
mileage 157000
the oil in the box changed 140,000
the problem is that the car does not go forward when starting after a night of inactivity
goes back without problems, but does not go forward until it warms up well for about 15 minutes
and even when it is turned on for a long time on D during warm-up, then D starts flashing
if you turn off the engine and then start it, it no longer blinks and starts to slowly get under way.
during the day there are no problems, everything works fine.

Hello!
