Chevrolet Lacetti. DISASSEMBLY AND ASSEMBLY OF THE TRANSMISSION, DEFECTS OF ITS PARTS - PART 1

You will need: keys "10", "13", "19", "24", a set of hex keys, flat-blade screwdrivers (2 pcs.), Round-nose pliers, circlip remover, bearing puller, hammer, beard, chisel.

1. Remove the gearbox from the car (see "Removing and installing the gearbox", page 158). Remove any dirt from it and wash the outside.

2. Using a screwdriver, pry the spring clip on the gear shift drive pivot pin.

Every owner of a Chevrolet Lacetti car may be faced with the need to dismantle the gearbox of his car and change the oil in it. A practical solution would be to learn how to do these manipulations on your own in order to insure yourself in case of unforeseen situations.

When operating a car, the Chevrolet Lacetti gearbox can cause a number of problems. These can be problems of the following type:

Noises appear when changing gears in a car;
Unexplained objective reasons for the increase in fuel consumption when driving around the city;
Clutch cylinders are leaking;
Long stroke;
Incorrectly selected gear ratios.

According to statistics, every second owner of a Chevrolet Lacetti car is faced with such a problem as long-stroke. To put it another way, the longer the amount of time the car continues to move in one gear, without switching, the more long-stroke the box is considered. The converse is also true.The driver experiences certain inconveniences in connection with this circumstance, since he constantly has to keep the engine speed under control.

Another feature that can cause inconvenience to the driver is the fuzzy engagement of the gear.

There are also a few more points: the box may crackle at the moment of gear shifting at low subzero temperatures; reverse gear may not turn on immediately, but after some time; handle travel becomes awkward in second and third gear.

In order not to face such unpleasant moments in the operation of the car, you need to constantly monitor its technical condition.

First of all, you need to keep the oil level in the Chevrolet Lacetti gearbox under control. Operation under the condition of a low oil level will lead to very rapid wear of car parts and its failure.

At the inspection pit, the box is diagnosed for leaks. Typically, leaks occur in the following places:

Differential cover;
The joints of the drive hinges with the box;
The joints of the cylinder block and the crankcase;
Gearshift rod.

If you observe any of the above in your Chevrolet Lacetti, it means that the box needs repair, for which you need to dismantle it. Below you will find instructions on how to dismantle the box, as well as how to reinstall it after repair.

This procedure may be necessary in order to repair the box or replace parts of the drive. Dismantling the box is a rather laborious procedure that requires skills and special equipment. Ideally, it is better for these manipulations to be performed by car service employees. The weight of the box is about 30 kg, so you need the help of another person or you need to use a special lifting device.

Remove the battery and shelf;
Remove the gear shift drive assembly;
Remove the drive shaft;
We disconnect the electrical connectors at the reversing light switch;
We disconnect the electrical connectors at the speedometer sensor;
We take out the hairpin;
Remove the clutch release cylinder tube;
Remove the connecting nut;
Remove the damping block bolt;
Unscrew the rear suspension bracket bolts;
Remove the bracket from the rear suspension;
Unscrew the mounting bolts of the rear damping block;
We remove the back block;
Unscrew the casing bolts;
Remove the upper bracket mounting bolts;
Remove the bracket;
Unscrew the box mounting bolts;
We select the box with a jack;
Unscrew the lower mounting bolts;
We remove the box;
We move the box towards the engine;
We put the box down.

Provide jack support for the box;
Insert the input shaft into the clutch disc;
Move the box sideways towards the car engine;
Tighten the lower mounting bolts;
Tighten the upper mounting bolts;
Install the casing and screw in the bolt;
Install the upper suspension bracket and tighten the bolts;
Tighten the bolts of the rear damper block;
Install the rear block;
Install the rear bracket and tighten the bolts;
Install the damper block coupling nut and bolt;
Connect the clutch release cylinder tube;
Connect the electrical connector of the speedometer sensor;
Connect the reversing light switch connector;
Remove the device used to hang the engine;
Install the drive shaft;
Install the gear shift drive;
Install the battery and the shelf under it;
Check the transmission oil level.

A number of problems associated with the box can be solved and without resorting to dismantling, it happens that it is enough to change the oil in the box and clean it.

Before proceeding with the manipulations, it is necessary to warm up the engine. It is better to change the oil after having driven the car for a while.Ten kilometers will be enough for the engine temperatures to reach operating values. Alternatively, you can warm up the engine in neutral at idle speed. A warm engine will drain the oil faster and more completely than from a cold engine.

Then it is necessary to install the Chevrolet Lacetti on the inspection pit, overpass, lift, since all working manipulations will be done under the machine.

Find the cap located next to the pallet;
Remove the cap;
Unscrew the breather plug using a 17 and 15 wrench;
Place a container under the pallet for draining the old oil, with a volume of at least 2 liters;
Unscrew the pallet nuts using a 13 wrench;
Remove the sump cover after all the old oil has been drained;
Remove the gasket;
Unscrew the level control bolt, as it has a magnetic tip, small metal particles are likely to adhere to it;
Reinstall a new gasket;
Screw on the cover.

Advice from experienced car enthusiasts: for greater reliability, it is better to use a sealant when installing the gasket. If you do not know the exact amount of oil to be poured into the box, then you should not tighten the control plug. Pour in the oil very slowly, when you see that it has poured from below through the control plug, then the process can be stopped.

It is most convenient to pour oil into the Chevrolet Lacetti box using the tube that comes with each oil canister. But a much more convenient option would be to use a large plastic syringe to change the oil in the box. Thanks to the use of a syringe, the oil will accurately hit everything as intended, and not spill around. It also saves a lot of time. You need to pour in oil slowly in order to hear its sound, focusing on this, you can understand in time that it is already worth stopping.

Now it remains only to tighten all previously unscrewed bolts. Be sure to check that nothing is leaking anywhere.

That's it, the gearbox oil change is complete.

The recommended oil change frequency depends on factors such as the driver's driving style and vehicle operating conditions.

In some cases, it is recommended to change the oil more often:

If the movement takes place in conditions of heavy traffic and frequent traffic jams;
If the fuel used is not of the highest quality;
Frequent engine start-stop operation;
If the car is used in conditions of high pollution;
If in winter trips are often made over short distances, and the engine is not given the opportunity to warm up properly before driving.

The regularity of oil changes is also influenced by the quality of the oil itself poured into the box.

The most suitable oil option for the Chevrolet Lacetti is synthetics purchased from a specialized auto store. Thanks to the choice of high-quality oil, the engine looks like new even on a car with high mileage. You also need to take into account the recommendations from the manufacturer, which are indicated in the documents accompanying the car.

Gearbox repair on Chevrolet Lacheti 1.8

… With a spanner wrench "17" we unscrew the three bolts securing the bracket to the clutch housing.

Remove the bracket for the rear support of the power unit assembly with the gearshift mechanism drive.
Before unscrewing the bolts securing the clutch housing to the engine block, mark their location. This will simplify the subsequent installation of the gearbox, since the bolts of the clutch housing are different in diameter and length of the rods.
At the top, the clutch housing is attached to the cylinder block with three bolts.

For clarity, we show the location of the upper mounting bolts of the clutch housing on the dismantled power unit.

Bolt 1 located under the ignition coils ...

... and bolt 3, which also secures the wiring harness bracket, turn off the head "19".

Bolt 2, located under the inlet pipe of the coolant pump, is unscrewed with a z-shaped key "19".
The inlet pipe of the coolant pump interferes with the operation of loosening bolt 2. To give mobility to the pipe ...

… From the rear side of the engine with the "10" head weaken the tightening of the bolt of its left fastening to the cylinder block (for clarity, it is shown on the dismantled engine).

From the side of the engine sump, turn off the two bolts of the lower fastening of the clutch housing to the cylinder block with the head "19", and with the head "14" - the three bolts of the lower fastening of the clutch housing to the oil pan.

From the side of the gearbox with the head "19" we unscrew another bolt of the lower fastening of the clutch housing to the cylinder block, and with the head "14" we loosen the tightening of the bolt of the lower fastening of the clutch housing to the engine oil pan.
Having unscrewed the nuts and bolt securing the base of the mounting block of fuses and relays in the engine compartment, we move the block away from the left support of the power unit, without disconnecting the pads of the wiring harness from the unit (see Replacing the supports of the power unit).

Using a spanner wrench or a "19" head, we unscrew the nut and bolt securing the adapter of the left support of the power unit to the support bracket.
We lower the power unit on an adjustable stop (placed under the engine sump), removing the bracket pin of the left support of the power unit from the hole in the support adapter.

Using the "14" head with an extension cord, we unscrew the three bolts securing the bracket of the left support of the power unit to the clutch housing ...

and take out the support bracket.
To facilitate the removal of the gearbox (weighs more than 20 kg), we install another adjustable stop under the clutch housing and completely unscrew (from the gearbox side) the bolt of the lower fastening of the clutch housing to the engine sump.

We take the gearbox from the engine to the left side member.
We lower the gearbox on an adjustable stop ...

The gearbox can also be removed without disconnecting the gearshift drive and the powertrain rear support bracket.
When removing or installing the gearbox, do not support the input shaft of the gearbox on the blades of the diaphragm spring of the clutch "basket" so as not to damage them.
Before installing the gearbox, apply a thin layer of grease, for example, SHRUS-4, on the spline part of the input shaft.

We check the condition of the two centering sleeves pressed into the holes of the cylinder block.
If bushings are missing or deformed, new ones must be installed.
Install the gearbox in reverse order.
After the introduction of the input shaft of the gearbox into the spline hole of the driven clutch dick, we push the gearbox to the right until the mating surfaces of the clutch housing, the cylinder block and the engine oil pan are in full contact. We screw in and tighten all the clutch housing mounting bolts. We install the support of the power unit. Finally, tighten the clutch housing mounting bolts with the required torque in the following sequence: - tighten the three lower mounting bolts to the cylinder block with a torque of 72–74 Nm; - one bolt of the lower attachment to the sump of the engine crankcase (next to the hole in the clutch housing under the drive of the right front wheel) - a moment of 30–32 Nm; - three more bolts of the lower attachment to the sump of the engine - with a torque of 20-22 Nm.
- tighten the three bolts of the upper attachment to the cylinder block with a torque of 72–74 Nm.
After installing the gearbox, fill it with oil, adjust the gearshift drive, pump the clutch hydraulic drive.

The manual transmission of the Chevrolet Lacetti rarely raises complaints, and with timely maintenance and oil change, almost all gears are engaged clearly and quietly. Its design can hardly be called innovative, but it is quite simple to adjust and maintain. How to adjust the rocker on the Chevrolet Lacetti, what is needed for this and when adjustment is necessary, we figure it out together.

The main problem with budget cars is the frequent use of inexpensive materials.

And this leads incorrect work the entire unit or unit. A lot of plastic bushings, clamps and adapters are installed in the Lacetti gearbox drive. They wear out over time, gear changes become indistinct and noisy, some speeds may not turn on at all.

The first sign that the gearbox rocker needs to be adjusted is increased backlash and shifting gears with effort.

Also, adjustment will be necessary in cases where the input shaft of the drive and thrust, say, after dismantling the box. Adjustment may not solve all problems, but the box will have more intelligible control.

More will radically affect the behavior of the checkpoint replacement of the wings or replacement of plastic bushings, latches and latches with polyurethane, but they do not appear on the market of spare parts. Therefore, we will adjust the stage with our own hands, fortunately, it will take at most 20-30 minutes.

The meaning of the adjustment is to set the gearbox control shaft and the rocker to their original position relative to each other.

To carry out the work you will need:

drill with a diameter of 5 mm;
key for 12;
Screwdriver Set.

Now you can start adjusting.

Set the gear lever to neutral.
We open the hood and find the place of fixing the gearbox drive shaft and traction drive.

The place of fixation is marked with an arrow.

Clamp and its loosening with a 12 key.

The latch is marked with an arrow.

We check the quality of the adjustment by starting the engine and turning on the gears one by one.

The adjustment is repeated if necessary.Thus, you can quickly and independently adjust the gearshift rocker on the Lacetti.

Repair of the transmission (gearbox) of the Chevrolet Lacetti can be major or partial. Repair of the transmission (manual transmission) of the Chevrolet Lacetti must be done only after the initial diagnostics in the car service. Very often, a third-party opinion that the box needs to be repaired turns out to be erroneous. It can also be caused by the clutch, flywheel, and gear selector.We offer two options for repairing a transmission (manual transmission):Partial (local) repair of the Chevrolet Lacetti gearbox - we remove the box, disassemble it, wash and defect. Troubleshooting a box is determining the cause of its failure, indicating a specific malfunction. A list of spare parts for this malfunction is also provided. After agreement, we make repairs to eliminate the specific malfunction that the client has contacted. We do not touch the rest of the components and spare parts in the gearbox.Overhaul of the Chevrolet Lacetti checkpoint - as well as with partial repairs, the box is removed and completely disassembled, washed and defective. In this case, we are not looking for a specific cause of the breakdown, but we are doing a complete defect diagnosis. All units and spare parts with increased wear, all bearings, oil seals and gaskets are determined and changed.Representative of Lacetti-Club in Pavlograd

You can change the differential yourself or at any service station. I've already tossed myself twice. Here is my theme, it has a photo report from the Aveo club ru with pictures:

If suddenly your satellites died - I can give my thanks for my thanks - this is the only thing that I have left in excellent condition.

How much did it cost you to repair the differential

I hung out the car and turned the wheels and did not notice anything outsider

Our differential in the collection itself costs up to 100 USD, the work - it all depends on the service station, I did not pay more than 200 UAH. At the same time, I changed the oil, since we do not have a drain plug and it is problematic to carefully drain it. By the way, the 75W90 performed much better than the native 80 W90. I also changed one inner fist - the backlash was audible only when the axle shaft was removed.

... and this is the question that interests me! What adjustments, tolerances, forces, etc. etc. And in general, who can do it. And then at the service station everything was quickly changed, tightened by eye and like go, everything will be OK, but knowing from personal experience adjusting the bridge in Zhiguli, I do not like this approach.

... We take the differential with the gear already installed, put it in the box, holding it with one hand, insert the other cover with the bolts.
The cover is also tight due to the rubber seal. For you need to tighten the bolts evenly and it sits in place.
And now the most important thing! Gently twist the toothed lid (the thread is very fine there).

We twist the differential until it dangles. Then you need to screw the cover three more teeth and fix it with a stopper. Thus, we adjusted the tightness of the differential bearings, which is necessary for their correct operation.

Then we assemble all the units in reverse order. ...

Every person who owns a car is faced with a gearbox oil change. Usually, the oil fluid is changed when the car has traveled 15 thousand km. More often, such mileage is observed in cars that have been operated in unsuitable conditions. These are conditions such as driving on poor-quality roads, untimely car repairs, cheap consumables, temperature drops and much more.

Small volume, closed spaces, rather high temperatures create conditions for the formation of various deposits. These deposits create conditions for the deterioration of the clutch operation, disrupt the operation of the car. Therefore, the sooner you change the oil product, the better.

Oil change in manual transmission Chevrolet Lacetti

Before replacing the oil product, it is necessary to read the manual for using the Chevrolet Lacetti car. In this manual, you can find information about gear oils that can be used for manual or automatic transmissions.

If it is not possible to use oil in the Lacetti box on the recommendation, then you can find out which analog is suitable - you just need to know the appropriate tolerance and look for it on other transmission fluids. When buying oil, it is better to consult with knowledgeable people if in doubt.

Ravenol 75w90 Getriebeoel TSG GL-4 1l - semi-synthetic transmission oil for the gearbox

More often they take an oil such as 75W90 RAVENOL TSG. This is a semi-synthetic product, used in machines that have a high level of load. Such oil has a fairly affordable price with good performance characteristics.

This type of oil fluid has many advantages:

Protects against wear.
Ensures stable operation if there are heavy loads.
It has optimal viscosity at temperatures higher than 40 degrees.
Has high thermal stability.
Has excellent shear stability.
The oil fluid remains in the same state under heavy loads.
The oily liquid only cools down at low temperatures.
Has good elastomer compatibility to prevent leakage.
Such oil contains chemicals that prevent the spread of corrosion and reduce friction.
This oil is available to everyone.

Changing the oil in the transmission at the service station

If you are faced with a problem like changing an oil product at a checkpoint, then you can contact a car service. Professionals work there, who will do the job efficiently and in a short time. Moreover, they make a partial replacement in the car. This is done by pouring a new product using the necessary equipment. It displaces oil and new oil is poured in. This procedure takes place in several stages. But there is a minus, because such work is expensive and this procedure will result in a pretty decent amount.

Therefore, if you are looking for a budget option, then you can change the oil in the Lacetti manual transmission with your own hands.

This is not difficult to do, there should be no problems in the process.Follow the instructions to make it work. This work has several simple steps.

There are many advantages to changing the oil yourself:

They save on it, because you only need to buy oil and some inexpensive tools that will be useful later.
Not so much oil is required.
When replacing, you can not only change the oil, but also clean the sump and drain plug from accumulated dirt and metal shavings.

Consumables for oil change in manual transmission Lacetti

To change the oil fluid, you will need these tools:

Transmission oil - two liter bottles are enough.
Pan cover gasket.
Key for 13.
Sealant. It is used for gluing the gasket to the gearbox pallet cover.
Empty container. Used oil liquid will be drained into it.

Important! Before you start changing the oil in the Chevrolet Lacetti box, you need to turn on the engine and drive several kilometers constantly switching gears. The liquid will become thinner and flow out faster.

Necessarily! Wear rubberized gloves before work.

The whole process of replacing transmission oil in a gearbox consists of the following stages:

Before starting work, you need to find a hole or overpass and drive there with your car. You can also just lift up the Lacetti. True, it will not be very convenient to work.

Chevrolet Lacetti manual transmission pallet

The engine will already be warm by this time, so only remove the engine crankcase if there is one.

Pouring new oil into the box

After the cover has been removed, carry out a visual inspection, if everything is in order, then you can mount a new gasket if it is already old. Then apply sealant in one layer and mount the pallet where it was.

Take a syringe or special watering can, which has a long tube and pour oil into the Lacetti box. Pour until the oil reaches the desired mark.

Then screw on the plug, attach the protection in place.

Check the oil level in the box.

That's all the actions that are performed when changing the oil in the Lacetti manual transmission.

Some people say that after they have made an oil change, the gearbox works perfectly, the gears shift more clearly, jerks disappear immediately, and the dynamics of the car improves.
