Before installing the gearbox, apply a thin layer of CV joint-4 lubricant to the splined end of the input shaft. When installing the gearbox, we orient it so that the guide pin in the cylinder block is located opposite the corresponding hole in the clutch housing, and the standard clutch housing pin is located opposite the hole in the cylinder block. We insert the gearbox input shaft into the splines of the clutch driven disc and push the gearbox all the way into the cylinder block. Use a screwdriver to unscrew the guide pin from the hole in the cylinder block. We carry out further operations for installing the gearbox in reverse order. Pour transmission oil into the gearbox.

The gearbox is the main unit after the engine. The Priora manual transmission is a reliable, modernized unit from 2110. The Priora's mechanics are filled with 3 to 3.5 liters of oil. Russian cars are chosen for their relative reliability, cheap spare parts, and endurance. If we take the manual transmission, then this is a reliable, unpretentious unit - although the box howls in 2nd gear, even when the car is new. The sales leader from 2012 to 2016 was the Lada Priora, especially in the Caucasus and CIS countries. It is well equipped and has decent technical characteristics. Since 2014, it has been possible to find cars equipped with an automatic transmission. The weakest Priora engine has a power of 87 horsepower, depending on the body type. The initial configuration of the Priora is a 1.6-liter eight-valve engine. It is equipped with a manual transmission.

Necessary tools for work

Changing the oil in a Priora gearbox will require you to use the following set of items and tools:

• a set of keys;
• gloves;
• old canister or 5-liter bottle;
• watering can;
• lift or pit;
• new oil in a volume of 3.5 liters of class GL-4;
• rags.

Characteristics of the Lada Priora gearbox

The base of the gearbox is represented by the following units:

• Clutch housing;
• Transmission housing;
• Rear transmission starter flap.

All elements are connected to each other with fixing nuts and sealant. The design is protected from contamination by means of a magnet that retains waste metal products. The main shaft is a set of gears that, when rotated, are connected to additional gears of all speed modes. The additional shaft is designed to regulate and distribute the oil emulsion.

How was the transmission created?

The new gearbox system is based on the previous design, which is familiar to many from the VAZ-2108. Naturally, the engineers made minor improvements. The weaknesses of this box are also well known to all owners of VAZ cars. Thus, among the weak points, many highlight difficulties when shifting gears, large shift lever strokes, a rather smeared shift pattern, and vibrations during operation.

All the details of the box - what's inside

The five-speed gearbox of the Lada Priora is connected to the central gear and differential. The Priora gearbox consists of shafts: the input shaft is made as a block of central gears. The gears of the forward speed modes have oblique teeth, the reverse gears have straight teeth. They contact the gears of the secondary shaft. There is an oil sump at the bottom of the secondary shaft in the bearing area. It is responsible for distributing the oil emulsion and supplying it to the secondary shaft, and then to the driven gears of all gears. The design of the gearbox includes a gear synchronizer. Synchronizers for 3rd, 4th, 5th gears have a similar design. The only difference is the blocking circles. The parts of 1st and 2nd gears have a different design. They have two cone-shaped friction areas installed, which relieve the load, distributing it evenly among themselves.

There is a magnet in the core of the clutch housing. It attracts metal waste and shavings and prevents its penetration into the system. A mandatory element of the box is the drive. It should be treated with special care. In addition to the listed parts of the box, it contains a jet rod, which is fixed at one end to the motor. Thanks to this, independent gear changes while driving are excluded.

The traction-controlled transmission has a three-arm handrail that activates the selected speed mode. A cable-operated transmission has a cable that activates the desired gear.

Lada Priora gearbox malfunctions and ways to eliminate them

Like any car component, the gearbox is subject to the negative effects of external destructive factors. The Lada Priora gearbox can also break down. The nature and frequency of breakdowns is influenced by management style, operating conditions, timeliness of maintenance, and quality of care. The manufacturer recommends changing the lubricant every 60,000 - 70,000 kilometers. The quality and correct choice of substance also affect the service life. Conventionally, all problems with a node are usually divided into two large categories: problems with the node itself or its mechanism.

The main types of faults are shown in the table:

There are a number of main reasons contributing to the breakdown.

Factors causing defects and breakdowns:

• Operating the vehicle improperly. Untimely maintenance, untimely oil change, insufficient quantity, operation of a vehicle with a faulty clutch;
• Poor quality parts of the unit;
• Operating a vehicle with worn-out parts or failing to replace them in a timely manner;
• Irrational replacement of parts performed by unqualified specialists.

The driver may suspect a faulty Lada Priora gearbox when symptoms appear.

Signs of a box malfunction:

1. The first gear is engaged with effort.
2. Switching occurs uncontrollably.
3. The car jerks while driving.
4. Transmissions are not included.
5. The presence of uncharacteristic sounds when switching modes: creaks, crackling, grinding.
6. Oil is leaking.
7. The car vibrates when driving.
8. The noise of the box when the engine is running, which disappears after the clutch is depressed.

It is problematic to accurately determine the nature of the breakdown, since the same sign may indicate different defects. To determine the breakdown, disassembly of the unit is necessary. Often the reason lies in adhesion, as these two elements are inextricably linked to each other.

To troubleshoot problems, it is necessary to dismantle the Lada Priora gearbox, replace worn parts, oil, and adjust the gaps.

Design Features

Manual transmissions are installed on cars with both front and rear wheel drive.

Despite the development of engineering and the appearance of automatic transmissions, mechanics continue to be used and improved. The reason for this popularity is no secret. Compared to analogues, this mechanism remains the simplest to manufacture and most reliable to operate. The only drawback of manual transmissions is that in city traffic jams, the variator turned out to be more practical. In recent years, the mechanics began to be equipped with a cable drive, and this made it more convenient.

What changed

Previous designs used a rocker to engage the gear. To put it very briefly, the rocker is a metal lever. When used, vibration from the engine is transmitted to the gear shift lever. Turning on and off was rough. All of the above and other shortcomings disappeared as soon as the cable structure was used in the box. Shifts became clear. The travel of the gear shift lever has been significantly reduced.

Subsequence:

1. Using a size 8 wrench, unscrew the nut of the drive housing. Disconnect the cable from the clutch pedal retainer.
2. Remove the compensation system box and ring from the pedal. To avoid damage, carefully pick out the box with a knife.
3. Remove the plastic sleeve from the pin. If there are signs of damage, replace with a new one. Lithol treatment is required before installation.
4. Remove the drive seal from the hole in the front of the shield.
5. Remove the tip, first dragging it in the direction of movement of the car.

The transmission of AvtoVAZ models has the advantage of simplicity of design and the ability to install it yourself if you have the necessary skills.

How to replace the clutch of a Lada Priora

The car's clutch is subjected to heavy loads - constant impact during the use of the car, engine vibration, very huge loads on the engine. The latter wear is usually accompanied by the corresponding smell of a burnt clutch.

The first signs include a feeling of incomplete clutch operation, extraneous sounds, and possibly even crunching sounds. The driver should not leave the clutch without replacing it after removing the box. clutch pedal may also sag , which also indicates that you need to change the clutch on the Lada Priora as quickly as possible.

But inexperienced car enthusiasts often have a logical question: how to change the clutch with your own hands? There is nothing complicated in this process, but it is necessary to stock up on tools and some knowledge.

Made with German precision

When this concept was transferred from paper to a real exhibit, and the mechanism began to work correctly, the module went to Germany, to. The Germans brought the knot to fruition. The company has long been developing various transmission systems and manufacturing engines. German experts carefully looked at the development of Russian engineers and proposed the following. Using a 3D center plate instead of a locking spring return system would make more sense. The special spatial shape of this plate was calculated using computer programs and manufactured using high-precision equipment. This accuracy is due to the fact that a special locking ball moves along the plate. And it is the plate that regulates the effort when selecting and engaging gears. The characteristics that the new cable gearbox will have were selected using a simulation stand. The man sat down on a chair and switched on various gears. Automatic systems simulate shift patterns, lever forces and strokes. And just like that, in small steps, the Germans managed to find the optimal settings. With the help of a computer, parameters and a mathematical model were selected, according to which these plates would then be manufactured.

Preparation

There are 2 ways to replace the clutch. Instructions for replacing the VAZ 2110 clutch with your own hands without removing the box and without the need to drain the oil + informative photo report + video. With the replacement of the clutch, replacement without removal, replacement of the Priora stove gearbox without. One method involves completely removing the gearbox, the other does not. In any case, the following available tools are needed:

See:

• jack;
• an overpass, without which it will be problematic to replace the clutch ;
• logs or bricks;
• a set of keys and sockets of sizes from 8 to 19, you may need a 15 socket, which is rarely required;
• extension cords for keys will not be superfluous, since sometimes a situation arises in which it will be impossible to reach the part by hand;
• mandrel 10-12 cm for centering the driven disk .

Replacement without removing the gearbox

This process is not too different from the first, as it seems at first glance. The preparation and tools are the same. However, in this case there is one big advantage - there is no need to move the rather heavy gearbox. Replacing the clutch without removing the box and without draining. This is especially true if one person is responsible for replacing the clutch.

In this case, the analysis should begin by removing the left wheel and placing the car on a jack. It is best to do this in a box where there is an inspection hole. In addition to the first points indicated in the first case, it is necessary to remove the air filter, unscrew the corrugation, disconnect the DMVR, and loosen the starter fastenings.

You will have to unscrew the gearbox, but there is no need to touch the CV joints. Since in the process of disconnecting all of the above, the bolts holding the engine will be loosened, you need to place bricks under it so as not to break the hoses.

Now the clutch can be changed as described above. As you can see, there is nothing complicated about this.

Quality of transmission lubricants

Dynamic viscosity - at low temperatures, in winter, the thickened oil resists shearing, which is a bad indicator in the operation of transmission units. Pour point is an indicator of the hardness of the oil in cold weather. But even when the lubricant hardens, there is a possibility that the gears can turn without applying torque to them. Viscosity index is a parameter characterizing the change in viscosity of transmission oil relative to temperature. If a car enthusiast wants his car to feel good on the road, he must constantly monitor the gearbox. Its regular inspection and maintenance of technical condition plays a big role in the operation of machine components.

To properly maintain the level, the oil in the gearbox is periodically topped up using a funnel and a hose attached to it.
