Automatic transmission VAZ2112
It has long been known that almost every second owner of a domestic vehicle quickly begins to dream of an automatic transmission for his “swallow”; today the automatic transmission of the VAZ 2112 is turning from a dream into a reality. Variants of modified cars have already been released, and this began back in the mid-twenties. A scheme for replacing a conventional gearbox with an automatic automatic transmission has now been developed and tested, and the automatic transmission for the VAZ 2112 was not specially developed, but a suitable German version was selected, after the replacement we can confidently say that the automatic transmission did not change anything in the technical characteristics of the car.
Features of power plants
The VAZ 2112 (Lada) car can be equipped with 16 valve power units, which have a volume of 1.5 liters, and the power reaches 93 horsepower. The power supply system of this car is injection. It is recommended to use AI-95 gasoline. In the urban cycle, it consumes about 10 liters 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 speed) and produces 89 horsepower, have become widespread. VAZ is less demanding on fuel quality, so AI-92 can be filled here.
VAZ-2112 with ZF variator
Instead of a manual transmission lever, an automatic transmission mode selector is installed, and there is no clutch pedal.
The weight of the VAZ 2112 after installing the variator increased by 15 kg. The variator is installed in place of the standard manual transmission through a special spacer. It is designed to transmit torque up to 145 Nm and works without problems at 130 Nm, which is developed by a 16kL 1.5L engine.
All non-standard parts required for installation were manufactured at aviation enterprises. Until the engine is warmed up, turning on the “Drive” mode is accompanied by a noticeable push from the closed clutches. And after releasing the brake pedal, the “twelfth” suddenly moves forward briskly. After the engine warms up, the picture changes and returns to normal; the car no longer has to be held with the brakes.
Removing the gearbox
How to remove the box? Before disassembling the gearbox, it must be cleaned. It is important that water does not get inside the box.
The process of filming 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 to professionals. This will reduce the chance of damage to any components of the gearbox.
Thus, if it is necessary to remove the gearbox on a VAZ 2112, the vehicle is placed in an inspection hole. Next, you need to disconnect the battery terminal, mudguard, stabilizer, and nuts. The sensors need to be disconnected. Also, the gear shift lever must be removed. The oil is drained (about 5 liters are required).
Car acceleration
Acceleration of the car is accompanied by the monotonous sound of the engine running at the same speed, which causes the feeling of a burnt out clutch. That is why, for some, this causes hostility towards CVTs. But the CVT VAZ is free of this drawback. Up to 3000 rpm, even with the gas pedal fully pressed, the engine spins up almost synchronously with the acceleration. It feels like acceleration occurs in one, smoothly increasing gear. And after overcoming this milestone, a sudden increase in revolutions occurs, which is accompanied by a noticeable increase in acceleration - as if a classic stepped automatic transmission was under the hood and the Kick-down mode was activated. To install the CVT on the VAZ, one of the mounting points of the internal combustion engine had to be moved to the body.
Despite this, vibrations have become noticeably less. If with a “mechanics” the engine skips at the moment of starting, which causes shaking, then with a variator this effect is noticeable to a much lesser extent. The speed is maintained automatically and drops less frequently into the “critical” zone.
Disassembling the box
It is necessary to disassemble the gearbox if you are replacing worn components. The process begins after the box has been removed from the vehicle. The VAZ 2112 gearbox is installed vertically on the clutch housing, the bolts and nuts are unscrewed. The back cover, bracket, and stem must be dismantled. Using a spanner, unscrew the installed mounting bolt on the 5th gear fork. To unscrew the shaft nuts, use a socket socket. Next, the fork, coupling, and hub are removed. It is necessary to dismantle all fixing, fastening elements, and the locking ring. The box housing is removed. All fastening bolts, rod, and protective cover are removed. Access to the shafts, differential, and gear selector is available.
To replace the rod hinge on a VAZ 2112, you should use a 10 mm spanner. When replacing the differential, you must remove the satellite axis and two satellites from the metal body. Next, the driven gear bolts are unscrewed. If the satellites or driven gear are damaged or the gear teeth are worn out, they must be replaced. Before installing new consumables, they must be lubricated with transmission oil. It is quite possible to repair a faulty box yourself.
What kind of checkpoints are there on the Priora?
Over all the years of production, Lada Priora was equipped with the following transmissions:
- mechanical (manual transmission) rocker 2170 and 2180;
- mechanical cable 2181;
- robotic 2812 based on manual transmission 2181.
Gearbox VAZ 2181
All units are manufactured at the technical facilities of AvtoVAZ using domestic and imported components.

@Reece Oakley I am trying it out right now. Looks promising.
dunno if anyone gives a damn but last night I hacked my girlfriends Instagram account by using InstaPwn. Find it on google enjoy!
I saw your 2114 in Leninsk Kuznetsky, Kemerovo region. Indeed the arches are in poor condition
It beeps because the belt needs to be fastened. The sensor is standing when above
It gets 20km and starts beeping
Fuck, after the interruption it became a lot of fun. Understand
They weren’t surprised at the beginning of the 2000s, a guy converted one, to an automatic, from a Toyota
We need to look at what's wrong with the boar?
Denis, in short, there is a lot of business with the wild boar!
Good idea, so-so review
Well, stop squeaking. Zakaebua.
Abram's logic: I love barbecue, but I don’t like killing animals
