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.

Regulatory parameters

The Priora car is equipped with a two-shaft manual 5-speed gearbox. It is the central component of the transmission system, which also includes the rear cover, gearbox housing, and clutch housing. A magnet is placed in the clutch housing socket to collect and hold metal debris.

The lubricant level in the gearbox must be constantly monitored. The successful functionality of the entire transmission system depends on how much oil is in the box. The established maintenance regulations provide for a mandatory check of the oil level in the gearbox after every 15,000 km. Detection of smudges or leaks involves immediate monitoring of the amount of lubricant present.

According to technical and regulatory characteristics, the Priora gearbox contains approximately 3.2–3.5 liters of transmission fluid. Car enthusiasts with sufficient experience recommend using 4 liters when changing the oil in a Priora gearbox. This quantity ensures quieter operation of the unit unit.

The accompanying documentation from the manufacturer indicates that the oil in the Priora gearbox is changed after 75,000 km. If this milestone has not been reached after 5 years, the lubricant will still have to be changed.

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.

List of recommended oils for Priora

The Tolyatti Automobile Plant prematurely gave its answer: “what to fill.” A whole list has been compiled of what can be poured into the Lada Priora gearbox with justification - a link to standards that confirm the quality of the product of each manufacturer.

The list of recommended automotive lubricants for the Lada Priora gearbox is as follows:

Rosneft KINETIC 75W-90 from 40 to 35; 80W-85;
Novoil Trans KP 80W-85;
Lukoil TM 412 75W-80, 75W-85, 75W-90, 80W-85, 80W-90;
THK Trans KP 80W-85; THK Trans KP Super 75W-90;
Tatneft Translux TM4-12 75W-85;
Shell Spirax; Shell Transaxle Oil 75W-90;
Trans KP-2 80W-85.

An important clarification regarding API groups: for almost all oils this is GL4, with the exception of Rosneft Kinetic 75W-90, Shell - they correspond to GL 4/5. The difference in viscosity is as follows:

75W is the degree of viscosity at which the crystallization (freezing) temperature is -45֯С, and begins to thicken at -30֯С;
80W is the degree of viscosity, which corresponds to a crystallization temperature of -30°C, and it begins to thicken at -15°C;
85W is the degree of viscosity for which crystallization begins at -15֯, and already at -10֯ it thickens.

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.

Step-by-step instruction

We warm up the engine and let it run for 10 minutes, then turn it off;
It is necessary to place an empty container under the drain hole - we will pour the old grease into it; The container should be placed under the drain plug and remove all oil from the system
Use the key to “17” to gradually unscrew the plug; the work must be done carefully; the oil will be hot; Unscrew the plug carefully
Now you need to wait until the liquid completely leaves the 16-valve system. We tighten the plug, the next step is to replace the oil filter;
If you have a special key, you can easily remove the filter. You can also try doing this by hand. If the filter does not budge, take a sharp screwdriver, pierce the housing and use the tool as a lever; Unscrew the oil filter using a special wrench or manually
Before installing a new filter, you need to fill it with oil (about half) and lubricate the gasket with it. This is done to prevent “starvation”, that is, the engine will not run dry. We install the new component and tighten it;
Now you need to fill the oil: unscrew the neck, it is located under the hood. Fill in about 3.2 liters and check the fluid level using a dipstick. If the level is between MAX and MIN on the dipstick, then you can tighten the plug. If there is a shortage, you need to fill in another 0.5 liters and check the volume again; Pour oil into the engine system and check the level with a dipstick
We start engine 16, it should run for 5-10 minutes at idle speed. Sit behind the wheel and watch the lubricant pressure indicator; it should stop working immediately after starting the engine. While the power plant is operating, you should examine the places where the work was carried out. It is necessary to ensure that there is no damage to the system;
We turn off the engine, wait 5 minutes and check the level. If it drops slightly below normal, add fluid;
Done, engine fluid replacement is complete.

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.

Preparatory activities

Changing the oil in a Priora gearbox consists of three stages: preparation, draining the waste and filling with new lubricant. Let's look at them in more detail. It should be remembered that the waste must be drained when the box is warm, it is better to do this immediately after a trip. Otherwise, you will have to leave and drive 2-3 km; idling the engine will not warm up the box. At the preparation stage, you need to collect some tools and available equipment:

Changing the lubricant in the Lada Priora gearbox

open-end wrench 17 for unscrewing the drain plug;
a container for used lubricant with low sides; usually a plastic canister with the side cut off is used;
a light source (an LED flashlight can be used) if there is insufficient lighting in the inspection hole;
a funnel for filling with a hermetically sealed tube 0.6-0.8 m long;
rags;
latex gloves;
protective glasses.

We drive the car into the inspection hole so that the left wheel is as close as possible to the edge of the hole; here the help of another person will be useful. This is necessary for more convenient access to the drain hole, which is located on the left side of the Priora gearbox housing. We secure the car with a handbrake or a wheel chock. If your vehicle has a sump guard installed, it will have to be removed. Now you can begin the replacement operation.

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.

View from the outside

A convenient and comfortable Priora car is one of the budget representatives of the sedan class. Manual transmission two-shaft, 5-speed. The box is assembled from three parts (sealant is placed between them): clutch housing, gearbox housing, rear cover.

A magnet located in the clutch housing socket holds metal debris and shavings. The drive gears of the input shaft are meshed with the forward gears. Oil is supplied to the driven gears through the hollow secondary shaft. It houses the forward gear synchronizers.

This unit is well assembled. And the synchronizers on the main switches are proof of this. Their operation is clearly adjusted, which reduces wear on the mechanical connection and noise when shifting gears. Accordingly, more durable operation of the Priora gearbox is ensured. But while monitoring the oil level, we should not forget that the quality of Russian roads leaves much to be desired. And this is one of the reasons for more frequent lubricant changes.

Leaks on the gearbox housing are also a motivating signal to action.

In order to check the transmission oil level, you must first place the car on a flat surface. Wait until the engine cools down completely. Remove the dipstick from the hole in the top of the box. Wipe it with a clean dry cloth and put it back

Then take out the dipstick again and pay attention to the marks located on it. The level should reach the maximum value

Visually assess the quality of the work. The main thing is not to miss the time when you need to pour new oil into the box.

Checking the lubricant level in the Lada Priora gearbox with a dipstick

The oil itself has two components: a base and an additive package. If the chemical composition of the base (base) is responsible for the property of the material, then additives correct the performance characteristics. This includes maintaining a certain temperature. The working fluid must not foam!

Playing the role of a lubricant, the oil also serves as a “broom”, cleaning the gearbox from technical debris.
