Correct operation of the Lada Priora car transmission is possible only with high-quality lubrication of its internal components and parts. The lack or use of used fluid will cause serious problems in the functioning of the gearbox, so every car owner should sometimes change the oil in the Priora gearbox.

When to change?

First, let's look at when it is necessary to change synthetic or semi-synthetic oil in the transmission system of a Priora car. According to the official regulations, the procedure for changing the lubricant is carried out after a mileage of 75 thousand kilometers. Or five years after the substance is poured, this is its service life. Taking into account the harsh conditions of vehicle use, experts recommend changing the lubricant every 50 thousand kilometers.

What signs may indicate the need for an urgent lubricant change:

There are deposits in the oil. Their formation indicates that the substance has lost its properties.
Burnt smell from gearbox. You can feel it in the cabin, but it will be more audible when you open the transmission inspection hole.
The appearance of difficulties with shifting the gearshift lever. Sometimes the selector is knocked out of its set position, this is due to malfunctions caused by the use of low-quality fluid.
Noisier operation of the unit.
Vibrations in the area of the gear shift lever.

How many liters of oil are in the Priora box: manual transmission and robot

According to the advice of car enthusiasts, when replacing, it is worth filling 4 liters at once, and the technical regulations indicate that only 3.2-3.5 liters should be poured into a manual transmission. The automatic transmission is filled with 2-2.5 liters. Checking the oil volume in the gearbox of a Priora car (16 and 8 valves) is carried out not only if there is a suspicion of its deficiency, but also after replacement. This way you can test yourself.

There are two marks on the engine dipstick - maximum/minimum. The principle remains the same: if the marks are somewhere between two marks, everything is fine with the gearbox, and if they are stuck at a minimum, it’s time to top it up, or even think about replacing it - so that the transmission works with fresh fluid.

From experience: when I poured 3.5 liters, when I turned on the reverse gear, the synchronizers creaked - after pouring more than 200-300 grams, this grinding noise went away when turned on.

What oil is better to use?

At the factory, during the production of cars, specialists fill in transmission fluid Lukoil TM 412, but its use is allowed only for running in the car. According to the manufacturer's recommendations, after some time the car owner should change the substance to a more recent one, taking into account the parameters specified in the service manual. The manufacturer advises using synthetics or semi-synthetics that correspond to the viscosity class 75W-90.

But here a lot depends on the region of operation, especially if you add oil for the winter:

75W - such a product begins to crystallize at a temperature of -45°C, but its thickening occurs already at -30;
80W - the oil loses its properties at -15°C, as it begins to thicken, but the liquid completely solidifies at -30;
a liquid with a viscosity class of 85W thickens already at -10°C, and it can solidify at a frost of -15.

As consumer reviews show, many car owners use Castrol 75W-90 Syntrax Universal or Zik Top oil with the same viscosity class. It is possible to use products from other manufacturers; it is important that the liquid is of high quality.

The RamaZ-Life channel provided a video that describes the problem of noise appearing from the gearbox of a Lada Priora car.

How much oil should be in the gearbox and checking the level

To purchase the required amount of oil, you need to understand how much fluid should be poured into the unit. The volume of lubricant that will enter the transmission is 3-3.3 liters.

The level checking procedure is carried out after placing the car on a horizontal surface:

Locate the volume dipstick; it is installed at the rear, at the top of the transmission housing. To gain access to the meter, you will need to remove the air cleaner housing and air duct.
Remove the dipstick from the inspection hole. Wipe it with a cloth and reinstall it completely again.
Pull out the meter and check the volume. Ideally, it should be located near the MAX mark.

If the gearbox does not have a dipstick, then the volume is diagnosed using the filler hole. The liquid level should be near the bottom edge. If there is less lubricant, it must be added to the system.

How to replace it yourself?

You can change the oil in the gearbox of a VAZ Priora 16 valve model of 2015 and other years of production with your own hands.

Tools and materials

The procedure for changing the substance occurs using:

wrench 17;
fresh lubricant;
a syringe with a connected transparent tube;
containers into which you will drain the “working off”;
clean rags.

You can learn about changing the lubricant yourself and all the nuances that the car owner will encounter during the task from the video shot by user ValeRiaN.

Stages of work

How to drain and fill fresh oil in a Priora gearbox:

The car is driven into a garage with a pit, onto a lift or onto an overpass. This is important because you will have to gain access to the underside of the car.
Depending on the fasteners, use a screwdriver or wrench to unscrew the engine mudguard fastenings. Set the splash guard aside.
Locate the drain hole on the vehicle's transmission. Place a container under it. Unscrew the plug of the control or filler hole, if there is one, or remove the dipstick from the neck, this will reduce the pressure in the lubrication system when draining the “working off”. If access to the dipstick is difficult, remove the air filter housing and move it to the side.
Using a wrench, unscrew the drain cover. Be careful when unscrewing. At first, the oil will come out of the system in a thin stream, but after the plug is completely unscrewed, it will begin to flow under great pressure. Use gloves. It is advisable that when draining the fluid the engine is not cold, due to this the substance will be more viscous and will drain out of the transmission faster.
While the oil is draining, visually assess the condition of the drain plug. If it is too dirty, clean it of debris and wear and tear. Check the condition of the seal; if it is badly worn, it is recommended to replace the part. Otherwise, you may encounter a problem with lubricant leakage.
When the liquid has drained, assess its condition. If the gearbox is functioning properly, it should be free of metal dust and other impurities. The presence of deposits indicates contamination of the unit, so it is recommended to wash it. To clean the transmission, the filler hole must be closed and flushing is performed using a special product. There is a large selection of such liquids; the product is purchased at a car store. To flush, pour about 1.3 liters of cleaner into the gearbox housing. Then the front part of the car must be hung, for this the wheels are placed on a jack. Start the engine and engage first gear, press the gas. Due to the fact that the front of the car is raised, you can drive in first gear for several minutes. After this, the procedure for draining the waste fluid from the system is repeated. If the flushing oil is too dirty after cleaning the unit, the procedure must be repeated. After this, wipe the drain and fill plug again.
Remove the dipstick from the inspection neck to check the level.
Now you can fill it, it is done through the control hole. You must pour fresh oil into the transmission using a syringe with a connected pipe, otherwise you will not be able to refuel the unit. One end of the hose is inserted into the control hole, on the other side the liquid is supplied into the system using a syringe. About 3.1 liters of oil is poured into the gearbox, the volume of the substance is controlled by the dipstick.
When the filling procedure is completed, install the meter in place. Reinstall all previously removed components in reverse order. When the process is complete, take a test drive of the machine and check the lubricant level again.

Changing the gearbox oil

Do-it-yourself priors will require preliminary preparation from the motorist. First of all, having purchased everything you need, you should park the car in a garage equipped with a pit, on a lift or overpass. After access to the bottom of the vehicle is gained, using a screwdriver or wrench it is worth dismantling the fastening of the power unit mudguard.

After removing the cover from the transmission drain hole, the motorist should place an empty 5-liter tank under it, which will help contain all the waste that comes out. Removing the control hole plug will help optimize the process. By pulling out the dipstick, the car owner will reduce the pressure in the structure. Sometimes at this stage it is necessary to dismantle the air filter housing.

If a motorist has decided when to change the oil in the box, he must first familiarize himself with all the theoretical information. In particular, prepare the tools, because without a “17” wrench it will be impossible to unscrew the cap covering the drain hole. It will take 10 - 15 minutes for the glass to lubricate the transmission, during which time it is advisable to start cleaning the plug. It is important to remove absolutely all wear products from it. At the same stage, the seal should be checked and, if necessary, replaced to eliminate the possibility of leakage.

After completely draining the lubricant, you need to check its condition; a normally functioning substance should be indicated by a light color, a burning smell, and the absence of impurities and debris. If there are any complications, the structure needs to be cleaned. With the filler hole closed, a special product is poured into the unit. There are many cleaners on the market today; you can choose any according to your capabilities. For cleaning you will need about 1.5 liters. substances. As soon as the liquid enters the unit, the front of the vehicle should be positioned so that the wheels are raised, this can be done using a jack. When the power unit is activated, the first gear is turned on, and you need to drive with a gentle pressure on the gas pedal for a couple of minutes. The next step is to drain the substance again. If the contamination is severe, the procedure is repeated.

After the dipstick leaves the control neck, you can begin to supply fresh lubricant into it. The peculiarity of the Lada Priora is that it will be possible to fill in new lubricant only using a syringe with a transparent pipe. In this case, one part of the hose should be in the control hole when the second is replenished with a syringe. It can take quite a long time to fill the 3.1 liter tank. oils In any case, the volume of liquid supplied must be regulated by the dipstick.

Once everything is done, the meter should take its place. Previously dismantled parts of the system have been reinstalled. Correct operation should be checked by a test drive and the opportunity to make sure that the level of the new fluid is in the required range.

What will happen if you don’t change it in time?

If the car owner does not change the lubricant in a timely manner, faster wear of the internal parts of the unit occurs. When an oil loses its characteristics, it becomes the reason why it cannot perform its duties.

This is fraught with the following consequences:

The friction components of the transmission operate under high loads, which leads to their rapid wear and failure. Bearings are the first to break because these parts work under heavy load.
When worn, metal dust flakes off the bearings, which can clog the lubrication system lines. Because of this, the pressure in it increases greatly, which leads to the squeezing out of oil seals and seals. This ultimately causes a leak.
As a result of wear of the bearings, sounds uncharacteristic of the operation of the unit will appear. The driver may also feel vibrations from the gear lever.
Due to problems associated with the operation of the unit, difficulties arise when changing gears. Sometimes the gearshift lever is knocked out of its set position. When changing gears, there may be a crunching noise and extraneous noise.

If internal parts wear out, changing the oil in the Priora gearbox will not solve the problem at the root. Damaged transmission components must be replaced.

Signs of malfunction, repair of the Priora gearbox

Transmission system failures occur for a number of reasons. For VAZ, this is primarily due to factory defects. Other sources of breakdowns include wear and tear of parts, mechanical damage, participation in an accident, untimely maintenance and systemic driving errors.

The Priora gearbox does not like sudden acceleration, extreme braking, or incorrect shifting. It is not so reliable that errors go unnoticed. The aggressive nature of driving will very quickly respond with noise and knocking out of gears. And this is a direct route to the workshop for repair of the Lada Priora manual transmission with associated costs. Forgetfulness of drivers in terms of maintenance also leads to unpleasant consequences. Thickened grease loses its effectiveness. Overheating and increased friction cause manual transmission mechanisms to fail even faster. After which a major restoration may be required, and possibly a replacement of the box.

Symptoms of a manual transmission malfunction

Noise, hum, or grinding noise in the gearbox may indicate wear on the gear teeth, bearings, or lack of fluid.
Difficulties in shifting may arise due to incomplete disengagement of the clutch, loosening of the hinge or lever. Deformation of the drive rod and jet thrust also leads to difficult transition to other gears. In addition, incorrect adjustment of the drive and deformation of the plastic elements of the gearbox control drive can lead to failures.
Knockout of gears occurs due to the wear of synchronizer teeth and increased engine vibrations on the supports. Due to incomplete gear engagement, incorrect drive adjustment.
Noise when shifting gears can occur as a result of incomplete engagement of the clutch and wear of the synchronizer locking ring.
An oil leak may occur due to the destruction of oil seals or the gear selector rod, loosening of the crankcase, damage to the gearbox cover, sealant, or drain plug.

To eliminate symptoms, the first step is to determine the root causes of the breakdown. It is impossible to do this in a garage. That is why self-repair is based on the assumptions and intuition of the “masters”. Such repairs of the Lada Priora gearbox always end in the same way. One repair is followed by the next, until the indirect or main cause is determined at random. At the same time, a complete solution to the problems of manual transmission may not be expected. This is due to the fact that one malfunction gives rise to another. And they can be eliminated comprehensively only in a professional car service. And the more you do self-repair, the more likely it is that you will have to look for a new gearbox on your Lada Priora. And this will be more expensive than high-quality repairs.
