The functioning of the vehicle is influenced by the conditions in which the machine will be used, how often its system will be serviced, for example, changing the transmission oil. Timely replacement of this fluid helps to extend the service life of the gearbox. The operation of the gearbox itself directly depends on the quality of the lubricant. Replacing the oil seal is a necessary procedure that is important to carry out if there is a fuel leak from the checkpoint.

The need to repair the Priora gearbox arises if the characteristic noise of the box began to arise when moving on the road. There are several reasons for the noise. In particular, this may be due to the fact that some of the component parts that are part of the box have worn out. Disassembly of the device is usually required. It is better to entrust the removal and disassembly of the checkpoint to professional craftsmen.
Gearbox pillows wear out over time. As a rule, because of this, the gearshift knob begins to rattle. Only original spare parts must be used for repairs.
Problems with the 2nd gear were initially, from the moment of purchasing this fret priors. Well, how can I say the problem, at first it did not turn on at all, then it began to turn on with a crunch (we are talking about a quick start and switching from 1st to 2nd at 6000-6500 rpm, there were no problems with normal driving).
On the recommendation of his father, he signed up for a service, where he repairs his car. (by the way, the service turned out to be very good, now only there :), located opposite the traffic police)
Since the box had to undergo an autopsy, I ran through the thought to put the 18th row and a pair of 3.9.
When they disassembled the box, in principle, they were not surprised by anything 😀
As a result, they were bought and exchanged
I also bought a Kalinovsky cardan along with an anther (you can pull the Priorovsky horseradish :)) and a short-stroke stage.
Symptoms: gears are shifted with complications, gears do not switch / do not turn on / do not turn off, rattling when changing gears, gears "knocks out", gears are turned off spontaneously.
Possible reason: the gearbox parts are out of order.
Tools: flat screwdriver, a set of heads, a set of wrenches, an assembly blade, a hammer, a technological plug in the gearbox hole for wheel drive.

37. Press out the front bearing of the output shaft using a special puller or screwdriver.
38. Dismantle the oil collector (it is located under the bearing).
39. Press out the input shaft front bearing using a special puller. If you do not have a puller, construct a hook-shaped fixture with stiff wire. Mount the manufactured device into one of the grooves in the crankcase and insert the hook under the bearing. Press the bearing out of the crankcase as follows:
- put a screwdriver in the hook;
- put a block of wood under the screwdriver;
- do not hit with a hammer on the opposite inserted end of the screwdriver;
- alternately rearrange the hook in the grooves.

- place the magnet in its place;
- Apply a sealant around the entire perimeter of the mating surfaces of the clutch housing and rear cover.
54. Install the gearbox.
Automakers around the world are not standing still in terms of technical progress. Every year, cars appear that surprise with their innovations in equipment and characteristics. AvtoVAZ does not produce high-tech cars, but from time to time the manufacturer pleases with updates of certain units. For example, the VAZ 2170, better known as the Lada Priora, is now equipped with an updated mechanical gearbox. Its main feature is the final drive and synchronization with the differential.
Structurally, the Lada Priora gearbox consists of three main units:
clutch housing;
gearbox housing;
rear cover of gearbox housing.
The units are connected to each other using bolt clamps, supplemented by applying a sealant. There is a special magnet in the pallet that catches metal elements, which are a product of natural resource development. The input shaft is an assembly with a set of gears that continuously mesh with driven gears of all available speeds. The output shaft is hollow and is used to supply gear oil. It contains all the driven gears of the forward speeds.
Two types of bearings are used on the shafts: at the back - ball type, at the front - with rollers. The oil sump is designed to redirect the oil flow into the hollow part of the shaft. Differential version - two-satellite. The main gear gear is attached to the flange of its box.
VIDEO
A breather is used to communicate with the external atmosphere; it is located in the upper part of the checkpoint.
The control is carried out through a lever and a knob for switching between speeds - a rocker with a cover. To prevent accidental engagement and disengagement of gears while driving, a jet-type thrust is integrated into the mechanism. It is connected to the motor at one end and to the base of the switch lever at the other. For greater sensitivity, some drivers install a short-stroke rocker as a refinement. On one side of the stem, a switch is fixed inside, which acts on the mechanism, it is a separate unit and is attached to the pallet. Three axes are fixed in the casing of the device:
The first one is used to attach the switch for selecting and turning on the speed, as well as two locks from the brackets.
The second goes through the slots in the brackets and prevents them from turning.
The third secures the reverse speed fork.
The gearbox has a special solenoid that blocks the spontaneous engagement of the reverse speed. Its middle part has a protrusion and does not allow the locking brackets to move along the axes until the reverse speed is engaged. The solenoid switch is located on the gear lever knob.When the ring rises, the electrical circuit is closed and the solenoid receives supply voltage. At the same time, the protruding middle part is pushed inward, allowing you to engage in reverse gear. If the ring is damaged, or there is a break in the electrical circuit, the reverse speed cannot be turned on.
VIDEO
To be able to get to the nearest car service, you need to dismantle the solenoid from the gearbox housing and install a plug that fixes the gear shift fork in its place. In this case, there is a risk of turning on reverse gear instead of the first and vice versa, so you should be careful.
After troubleshooting, it is necessary to add oil to the crankcase, as part of it will leak out when the solenoid is dismantled.
The manual transmission of the Lada Priora is far from ideal and has a number of characteristic faults. Problems common to all manual transmissions also occur. Conditionally, they can be divided into breakdowns in the box and in the gearshift mechanism. The first include:
damage to synchronizer couplings and their spline connections;
gear wear;
oil leakage and lowering of its level in the crankcase;
development of the resource of bearings on the shafts (primary, intermediate and secondary);
deformation and damage to oil seals;
weak connections.
Breakage in the switch mechanism:
defect in the drive rod - damaged, weakened, dangling, acidified and worn out;
worn stock, backlash in mechanisms;
deformation or wear of the locking mechanism;
the fork is worn out.
The reasons why certain faults of the gearbox and the gearshift mechanism most often occur:
VIDEO
the operating rules are violated - insufficient oil level, poor-quality lubricant, driving with a faulty clutch;
low quality spare parts;
the resource of parts has been developed (natural wear and tear);
improper maintenance and repairs by unqualified personnel.
A fault in the gearbox can be found out by a number of external factors:
transfers are included with difficulty;
spontaneous inclusion of gears (gears fly out)
gears do not turn on or turn on with great difficulty and extraneous sounds, the car jerks on the go;
the gearbox makes noise, when the clutch pedal is pressed, the noise disappears;
extraneous sounds when switching gears - grinding, crunching, squealing, bouncing, creaking, vibration;
oil leak.
When carrying out diagnostics, it should be borne in mind that the same symptom may indicate several malfunctions at the same time. Setting the exact cause is carried out only after removing and disassembling the gearbox. Qualification and experience are required to carry out repairs and identify worn or damaged parts.
Many malfunctions can arise from clutch malfunctions, since the two are inextricably linked in the gearshift mechanism. For this reason, proper qualifications are needed to diagnose breakdowns, as well as to repair, troubleshoot and install new parts.
VIDEO
There is only one way of troubleshooting: disassembling the unit and replacing damaged parts, as well as adjusting the clearances.
To work you need a set of tools:
screwdrivers;
set of socket heads;
spanners;
assembly blades;
hammer;
plug for the drive hole (inner CV joint).
Before starting dismantling, drain the oil from the gearbox housing. The scheme of actions for removing the box looks about the same, the algorithm differs only when dismantling a robotic gearbox:

VIDEO
This completes the dismantling, it remains to lower the assembly and proceed with further disassembly, troubleshooting and assembly with new parts. Installation is carried out in the reverse order of removal. After installation, fill with new gear oil to the optimum level. For reliability, overflow is allowed above the maximum mark by 100-200 ml. This is due to the high position of the fifth gear, which often lacks lubrication.
The Lada Priora checkpoint is not the best, but at the same time it has a simple device and can be repaired in a garage with your own hands if you have certain knowledge and skills of such work. For convenience, it is better to dismantle with an assistant. The checkpoint is a heavy knot, and when removed without insurance, you can easily drop it on yourself, getting injured.

The line of Lada Priora models - VAZ-2170-2172 - has existed for 7 years and over the years has gained many fans. This is a budget car, the design of which is considered among the owners to be not fully finalized, therefore, you should especially carefully monitor the serviceability of all technical units. Unfortunately, cases of malfunctions in the operation of important components, including the gearbox, are detected in the very first months of operation. During the break-in period of the car, it is much easier to eliminate design flaws than after a solid run.

Priora gearbox and its typical breakdowns Gearbox vaz priora does not differ much from the box of the 12th model: five-speed, mechanical, combined in one crankcase with a differential and a main gear. Like its predecessors, this car shows its strengths and weaknesses during operation. Here are some typical faults gearbox lada priora : incomplete or spontaneous engagement and disengagement of the clutch, jerks and extraneous noise in the box, oil leakage. They can be easily removed in our car service after thorough diagnostics carried out by an experienced specialist.
Changing the gearbox is a practical solution If the car already has a solid mileage, it is better not to repair the gearbox, but to change it. We can gearbox prior to buy and install in a short time and at an affordable price. Self-replacement of the prior gearbox for many car owners is not difficult, but it is better to entrust this work to a professional who knows all the features of the car and has experience in carrying out this operation.
The gearbox is being improved In 2010, AvtoVAZ modernized the gearbox on the Priora, reinforcing the output shaft by installing needle bearings and a new type of gears. The new unit has become much more reliable and durable. In our car service you can install Priora gearbox of a new type for a car of any model year. Sitting behind the wheel of the updated Lada, the driver will immediately feel the difference in the control and movement of the car, if earlier there was prior gearbox of the old model ...

Computer diagnostics will help to determine breakdowns.
Gearbox tuning is a great opportunity to improve the Lada Priora. We also have all the possibilities to produce any tuning gearbox prior - the selection of a complete set is made in accordance with the operating conditions of the car: race, city, track, as well as with the characteristics of the engine and the desired speed limit. You can choose a tuning kit by reading photo of the Priora gearbox in our catalog, as well as with the technical characteristics of each set. We have a wide selection of non-standard configurations with a variety of gear ratios. For fans of a sporty driving style, street racers in our car service can be configured sport gearbox prior , which allows you to realize the maximum potential of the engine. The conventional range of gearboxes is designed for average engine performance, while the sports range with an increased gear ratio redistributes the engine torque to the required speed range and thus brings the dynamics of the car in line with the tasks set.
Timely repair, exchange and tuning of the Lada Priora gearbox are the types of work that will increase the service life of this flagship of the Russian car industry and give it new, wider opportunities. In our car service we will help to bring the car to a high level.
Lada Priora is a modern, comfortable car that has a manual transmission with five forward gears and one reverse. Synchronizers are available on all main switches. Structurally combined with differential and final drive. The gearbox housing consists of three cast steel parts:
The operating mode and service life of the Priora gearbox is fully dependent on the availability of lubricant and operating conditions. Therefore, it is necessary to constantly monitor the oil level in the box and do not forget to change it in time. According to the technical characteristics of the Priora manufacturer, the transmission oil must be changed every 75,000 kilometers or after 5 years. Whichever period comes earlier, on that and rely.
Where torque is transmitted by gear pairs, including in a gearbox, transmission oils must be used.
Dynamic viscosity - at low temperature conditions, in winter time, resistance to shear of the thickened oil occurs, which is a poor indicator in the operation of transmission units. The pour point is an indicator of the hardness of the oil in cold weather. But even when the lubricant solidifies, there is a possibility that the gears can turn without applying torque to them. The viscosity index is a parameter that characterizes the change in the viscosity of the transmission oil with respect to temperature.If a car enthusiast wants the car to feel good on the road, he must constantly monitor the checkpoint. Its regular check and maintenance of technical condition plays an important role in the operation of machine units.
To properly maintain the level, the oil in the gearbox is periodically topped up using a funnel and a hose put on it.
In this table, gear oils are classified by quality. The letters indicate the quality and scope of the grease, and the numbers indicate the temperature regime. When using synthetic materials, the temperature limits expand, which is not possible with mineral oils. In the process of using oils in transmissions, changes in their physical composition occur.
All these lubricants belong to the same technical group and can be chosen by each motorist at their discretion. Individual assessment of products, payment for work on its change, the desire to keep the transmissions in working order as long as possible - all this will help to choose the transmission oil for the Priora car produced by AvtoVAZ. When buying a car, each driver should carefully read the "Priora Operation Manual", where you can find the recommended brands of oils for cars and their characteristics. When choosing a lubricant for Priora, pay attention to the climatic conditions and the intensity of use of the machine. Conclusions:
Bon voyage and don't forget about the correct choice!
The replacement of the hinges of equal angular velocities on the Lada Priora car is carried out if there is a knocking or grinding noise in the drives when cornering, they are also changed if the anthers are damaged or when there is a backlash in the transverse direction. It makes no sense to disassemble and repair the hinge, since the dirt that got through the torn boot has already brought its parts to [...]
