The reasons for the breakdown may be different, perhaps the timely oil change did not occur or the mechanism, simply, has exhausted its resource.
How is the VAZ 2110 gearbox repair carried out? Do-it-yourself VAZ 2110 checkpoint repair, video.
There are situations when the removal of the gearbox is not at all necessary, it is enough to adjust it. VAZ 2110 very often have problems with gear shifting, they are knocked out. To eliminate this problem, it is not at all necessary to remove the box, it is enough to adjust the gear selection drive mechanism. It is enough to get by with the adjustment in the following cases:
In the above situations, a simple gearbox adjustment will suffice. This is much better than repairing the VAZ 2110 gearbox, disassembling and assembling the gearbox.
Below you can see the repair of the VAZ 2110 gearbox with your own hands video.
Having started to repair the VAZ 2110 gearbox, after all the actions described above, it is required to disassemble the crankcase and the working mechanism. Getting started:
Dismantling of the VAZ 2110 gearbox is completed.
The problem concerns the first transmission rate. It turns on very hard, when shifting gears, an extraneous sound is emitted, the speed flies out while driving.
The next problem concerns the second gear. Most often, motorists are faced with the fact that the second speed jumps out or there are difficulties when it is turned on.
Very often, in order to fix the problem with the second speed, you just need to change the fixing spring. If, after replacing the spring, the speed continues to fly out, then you need to remove the gearbox and make a major overhaul.
The occurrence of extraneous noise in the gearbox may be due to bearings that have failed. In order to find out, you need to check the backlash of the roller bearings that are installed in the clutch housing, the rolling bearings located on the primary and secondary shafts.
You need to check the forks and gear rods very carefully. These parts tend to deteriorate very quickly. If there are any obvious signs of deterioration of these mechanisms, then they must be immediately replaced with new ones. You can buy these parts at car dealerships.
If a motorist has a little experience in repairing a VAZ 2110 gearbox, then he can safely repair the gearbox on his own. From this article, it is clear that this is not so difficult to do. Even a car owner, who does not have enough experience and skills, can cope with this problem. But if, nevertheless, a person is far from this, and has no idea what and how to do, in this case, turning to a specialist for help will be the right decision. Of course, when contacting specialists for help, it will cost the car owner a certain amount of money. But it's better to pay the money and get a quick and high-quality gearbox repair.

A manual transmission is a set of gears that, in different combinations, mesh with each other and form several gears with different gear ratios. The key advantages of this mechanism include a relatively low price, high efficiency and simplicity of design. Also, a car with a manual gearbox is economical and has good acceleration dynamics.
The manual transmission was invented by Karl Benz, who created an imperfect model of this unit for his car in 1886. Gradually, this mechanism, which helps the vehicle to adapt to different driving options, has become more complicated and now it is the most popular in the world.
Like any mechanical device, the gearbox is not insured against breakdowns and damage, so car owners are sometimes forced to leave their car for repairs. The gearbox also periodically fails, and at the same time motorists turn to specialized services to carry out repair work.
There is another option for restoring the operability of a manual transmission, which involves the independent performance of work. To do this, you need to remove the manual transmission, disassemble and replace the necessary parts, and then assemble everything in the reverse order. To do this, you need to have some experience and have a certain set of tools, otherwise the repair can be very delayed.
A manual transmission consists of a large number of components, each of which can break.
Below we will consider the main reasons for a transmission breakdown and figure out how to remove the mechanism from the car.
When shifting the lever to neutral, an abnormal noise is heard. In this case, the matter may be in the low quality of the lubricant or its absence. If, after changing the oil, the noise in the manual transmission does not disappear, it may be due to wear on the input shaft bearings, defects on the gear teeth or shaft displacement. In the event of any of the listed malfunctions, the necessary elements must be changed.
Gear shifting tight. The case may be a breakdown of the gear selection mechanism, a defect in the cardan joint or an incomplete clutch release. Also, the difficult operation of the manual transmission is sometimes caused by the weakening of the fasteners of the bolted connections or damage to the stem lever.
In this case, it is necessary to adjust certain elements and replace the damaged gearbox parts.
The gears are switched off by themselves. This malfunction can be associated with wear or damage to the gear teeth, loosening of the second shaft nut, wear of the rods and deformation of the forks, as well as increased vibration of the motor during operation. To solve the problem, you need to replace the defective elements and adjust the drive.
Extraneous sound when switching gears. The main reason for this is a breakdown of the clutch mechanism. Also signs of a malfunction may be oil leakage from the gearbox or increasing noise when the machine is moving in higher or lower gears. In the first case, you need to check all oil-containing elements for wear and replace them, and then change the oil. In the second case, the matter may be in the failure of the secondary shaft bearings, which require replacement.
Dismantling the VAZ 2110 gearbox is a simple task. Before that, you must first disconnect the negative terminal from the battery power and remove the mudguard. After that, the stabilizer is removed from the box and the oil is drained from the system. At the next stage of work, the clutch boot and the drive system are removed. After that, you need to remove the connectors of the speed and reverse sensors. The bracket can complicate subsequent actions, so it is better to remove it and put it aside, and then dismantle the left engine mount and unscrew the manual transmission mounting nuts. Now the gearbox can be removed and you can start repairing it yourself.
Repair of the gearbox can be done by hand at home. Using a wrench, you need to unscrew the bracket with which the gearbox was attached to the motor. After that, you need to dismantle the rear cover of the manual transmission. To disengage the transmission, it is necessary to push in or pull out the stem. After that, unscrew the fifth gear fork and turn it on with light blows on it. After that, you can proceed to the next stage of the gearbox repair.
To dismantle the fifth gear, you need to unscrew the nuts of the shafts - primary and secondary. At the next stage, the fifth gear is disassembled into its component parts:
We take out the plug.
Remove the clutch.
Let's dismantle the synchronizer.
We take out the thrust washer.
After completing the described work, you need to remove the fifth gear gear by lightly tapping on the input shaft until a small gap appears, which will simplify the procedure for dismantling the gearbox element. The rods and the locking plate can then be removed without any problems.
After sliding the thrust washer, you can remove the bushing and remove the circlip from the input shaft. The secondary shaft of the manual transmission is subjected to the same procedure. After that, you can pull out the input and output shaft together. Next, the mechanism responsible for the selection of gears is removed, as well as all its elements.
Using a special hook, we remove the shaft bearings, and knock out the oil seals and differential bearings.
After a complete disassembly of the VAZ 2110 manual transmission, you need to inspect for damage. Next, you need to replace certain parts and assemble the mechanism in the reverse order.
To ensure the long service life of the manual transmission and its normal operation, certain rules must be followed when assembling the unit.
For example, when installing the gear selector lever, carefully degrease the threaded holes and all mounting bolts.The edge of the manual transmission oil seals must be coated with oil, and the clutch retainer must be coated with grease.
We treat all surfaces of the mechanism in contact with each other with a sealant. For clarity, see the diagram of the VAZ 2110 manual transmission.
You will need: a socket wrench (head) "for 10", "for 13", "for 32", keys "for 10" and "for 17", a large screwdriver, a bit, a hammer, pliers for removing retaining rings, an impact screwdriver.

It may be necessary to carry out work on dismantling the gearbox, both for performing repair work on the drive gears and for replacing the clutch. There is nothing difficult in performing such procedures, but they should be performed on a lift or in a pit, and best of all in the company with an assistant.
Handbrake + rear-wheel shoes = safety first
Before proceeding with the dismantling of the gearbox, ensure the car is in a level and stable position, make sure that wheel chocks are installed under the rear wheels. Lift the parking brake lever up as far as possible.
First of all, open the hood and turn off the power from the battery.
Next, we detach the clutch cable from the fork, taking it out of the place of fixation on the gearbox itself.
We take out the cable from the bracket
Seat speed sensor.
The old oil is drained from the gearbox.
A capacity of at least 5 liters is required
We remove the torn off bolts to the side.
We remove the weakened lever according to the diagram.
Almost done. The CV joint is already on the drive.
We unscrew the fasteners and remove the ball joint from the fist
The bolts are indicated by arrows. Under the number "1" - the crankcase, "2" - the gearbox housing.
When the box does not hold anything, we remove it to the side.
Now that these works are completed, you can continue to perform the next stage depending on your goals.
Installation and assembly of the gearbox should be carried out in a similar manner to removal.

I have already rented the gearbox twice, you can say a professional now in this business))).
Loosen the bolt on the gear selection cardan. So as not to customize. Bolt with cone. He will enter himself. Loosen the two bolts securing the ball joint to the steering knuckle. The left "sword" can be left on. It is easy to move the checkpoint on it. If there is no hole, put the checkpoint back over the top of a suitable type of goats, as on which the logs are sawed. Only instead of a log there is a tube on which a rope is wound. The rise is done by twisting the pipe, the second is pushed into place. Another variant. The checkpoint is put on two or three tires (in front of the car it is raised as much as possible), pushed under the checkpoint place under the hood, and lowered in front of the car. Then they are pushed onto the engine. Thanks to all. And don't strain your lower back!
The VAZ 2112 car is one of the common models that the Volzhsky Automobile Plant offers to purchase. The car is a 5-door hatchback. On this generation of cars, an increased luggage compartment is noted. The material of the interior trim is distinguished by its durability, which attracts many people with this model.
The VAZ 2112 (Lada) car can be equipped with 16 valve power units, which have a volume of 1.5 liters, while the power reaches 93 horsepower. The power supply system of such a car is injector. It is recommended to use AI-95 gasoline. In the urban cycle, about 10 liters are consumed per 100 km. The VAZ gearbox in this case is mechanical.
Cars with a 1.6-liter engine, which is equipped with a manual transmission (5 tbsp.), Produces 89 horsepower. VAZ is less demanding on the quality of fuel, so AI-92 can be poured here.
How to remove the box? Before disassembling the gearbox, it must be cleaned. It is important that no water gets inside the box.
Main stages:
Battery power is cut off.
The block is disconnected from the speed sensor.
The transmission fluid is drained.
The bolts fixing the jet thrust are removed.
It is necessary to remove the constant velocity joints from their regular place.
The existing ball joint bolts are loosened.
Using a tool, the nuts holding the clutch cover to the box crankcase are unscrewed.
The bolts securing the gearbox to the motor are disconnected.
The power plant must be raised (it is worth using a jack).
The engine mountings are subject to dismantling.
You can use a screwdriver to hook up the gearbox.
The speed box slides off the rails. The input shaft should come out of the clutch.

The process of shooting from a regular location requires caution. That is why this procedure should not be carried out alone. Repair of a VAZ gearbox, its dismantling and assembly should be trusted by professionals. This will reduce the chance of damage to any of the gearbox components.
Thus, if it is necessary to remove the gearbox on the VAZ 2112, the vehicles are placed in the inspection pit. Next, you need to disconnect the battery terminal, mudguard, stabilizer, nuts. Disconnect the sensors. Also, the gear lever is subject to removal. The oil is drained (about 5 liters needed).
It is necessary to disassemble the gearbox if you are replacing worn-out components. The process begins after the box has been removed from the vehicle. The VAZ 2112 gearbox is installed vertically on the clutch housing, bolts and nuts are unscrewed. The rear cover, bracket, stem are subject to dismantling. Using a spanner wrench, the installed mounting bolt on the 5th gear fork is unscrewed. Use a socket head to loosen the shaft nuts. Next, the plug, coupling, hub is removed. It is necessary to dismantle all fixing, fasteners, retaining ring. Removal of the crankcase is carried out. All mounting bolts, stem, protective cover are removed. Access to the shafts, differential, gear selection lever is opened.

To replace the stem hinge on a VAZ 2112, use a 10 spanner wrench. When replacing the differential, it is necessary to remove the satellite axis and two satellites from the metal case. Next, the bolts of the driven gear are unscrewed. If the satellites, the driven gear are damaged or the gear teeth are worn out, they must be replaced. Before installing new consumables, they must be lubricated with gear oil. It is quite possible to repair a malfunctioning box with your own hands.
The oil in the gearbox for the VAZ 2112 should be purchased from trusted companies, for example, ZIC, Liqui Moly, Xado. Using semi-synthetic oils, the owner of the car extends the working life of the gearbox. In particular, the 75W-90 option is suitable for the VAZ 2112. It does not lose its working properties if it is subjected to high loads.
