On the car, depending on the configuration, are installed five-speed boxes Renault JH3 and JR5 gears, as well as VAZ-21809 (since 2018), made according to a two-shaft scheme with synchronizers for all gears forward and combined with differential and final drive. In the gearbox at the factory pour transmission fluid, which is designed for the entire life of the car. Therefore, it is not necessary to change the oil in the gearbox according to the terms of maintenance.

Car engine, like all engines internal combustion, develops power and torque in a relatively narrow rev range. When the engine speed decreases, the power decreases
The power train allows you to reduce the number of revolutions of the drive axle in relation to the number of revolutions crankshaft engine, increasing tractive effort. The higher the pull force, the less speed movement.
When driving a car, it becomes necessary to apply different speeds and different traction forces. So, for example, when driving on deep sand, the speed is negligible, and to overcome the resistance of the road, a rather large traction force is needed. A large traction force is also required when starting the car from a place and overcoming steep climbs. On the contrary, when driving on a paved road, little tractive effort is needed, and the driving speed can be high.
To increase or decrease tractive effort on the drive axle with a constant torque on the motor shaft in power transmission vehicle is using a gearbox.
Since the engines various models car have different power, then, of course, the gear ratios of individual gears, and, consequently, the number of gear teeth are different. However, the principle of operation of gearboxes is the same, and the operations for disassembly, assembly and repair are generally similar.
The purpose of the gearbox is to provide further transformation of the torque in magnitude and direction in accordance with the load on the car, as well as to create the possibility of the engine running at Idling.
The basic principle of operation of the gearbox is the same everywhere, the essence of which is the pairwise connection of gears that have a different number of teeth. In this case, the torque transmitted by the gears changes in proportion to the gear ratio, i.e. the ratio of the net teeth of the driven gear to the number of teeth of the drive gear.
The gearbox is, in principle, a very simple device.

Checkpoint identification
Definition established checkpoint by configuration and engine (only for Renault engines)In more detail, the ratio of engines and gearboxes is indicated
According to the manufacturer's instructions, engine oil to Largus is subject to change every 15 thousand km. Depending on the operating conditions, a more frequent change is also possible (after 7-8 thousand km.). You also need to change the filter.
The Lada Largus car is produced with two types of engine models: 8-valve K7M and 16-valve K4M. The volume of the poured motor lubricant For different models is 3.3 liters and 4.8 liters, respectively.
To the choice motor fluid must be approached responsibly. ICE operation depends directly on this consumable. The factory is initially filled with ELF SOLARIS RNX 5W-30. Also, the recommended oils are API SL, SM, SN. Experts also suggest using the ACEA A1 / A2 / A3 / A5 quality class. The level of viscosity also matters. By SAE classification choose 5W30, 5W40, 0W30, 0W40. It all depends on the climate of the area.
Filling procedure for new lubricating fluid into the car engine
The process of draining mining
Before starting work, you yourself need to prepare the necessary improvised materials. Namely:
- transmission fluid;
- Oil filter;
- Key on "10" and square on "8";
- Clean rags;
- Container for draining mining with a capacity of at least 5 liters;
- Brush, preferably metal.
Work is performed on a warm engine. After a short trip, you need to drive the car onto a flyover. First, unscrew the filler cap. Then, using a metal brush, clean the cork drain hole. It is located on the underside of the engine crankcase. When unscrewing the cork, you must be especially careful not to get burned. Drain the waste into the prepared container. This will take 10-15 minutes. Degrease the plug and screw it back on.
Another important point: The steel washer under the plug must be replaced if the rubber seal is damaged.
Installing a new filter
First of all, it is necessary to remove the protection on the engine (for K4M, 16 valves). To do this, unscrew the six screws with a “10” key. The filter part is removed counterclockwise. The container for draining should be ready. If missing special tool to remove the filter, you can use a screwdriver as a lever.
Now fill new filter about 1/3 full of grease, lubricate the O-ring and reinstall.
The bay of a new motor substance in a Lada car
Pour prepared lubricant through the oil filler neck. The quantity depends on the type of engine (16- or 8-valve). The dipstick will indicate the level of the filled substance. The mark should be in the middle between the maximum and minimum value.
Now you need to warm up the engine at idle. Approximately 3 minutes after starting the engine, the emergency flasher will go out. If no oil leaks are found anywhere, then everything is done correctly. After turning off the engine, re-evaluate the level of the poured consumable. If necessary, it must be topped up to the appropriate norm. The norm for the 16th and 8th model of the Lada engine is determined in the same way.
Replacing the transmission substance at the Lada Largus checkpoint
One of the most expensive and significant components of any car is the gearbox. And high-quality and timely care for it will extend the "life" of the car. If you believe the instructions attached to the car Lada Largus, the engine oil in the transmission is poured for the entire period of operation. But in fact, its replacement is simply necessary. You need to control the level every 10-15 thousand km. Shifting problems or extraneous noise and sounds directly signal the need to change the lubricant.
It is only necessary to fill in oil intended for the Largus checkpoint - TRANSELF TRJ 75W-80.
Service vehicle: "exploitation" of the lubricating fluid
Stages of work
Insert a hose with a funnel at the end into the filler neck. Pour new oil into the funnel in the amount indicated in the instruction manual. It will be about 3 liters.
Oil selection
The most economically advantageous and in terms of performance characteristics is semi-synthetics for internal combustion engines (16 or 8). His detergent properties much higher than that of the mineral. And in the cold, the car is easier to start.
A synthetic substance is excellent in the engine in the gearbox of a Lada Largus car. It will be the most acceptable. The viscosity grade is marked with the number 75W90, and the quality is API GL-4.
And a little about the secrets of the Author
My life is not only connected with cars, namely repair and maintenance. But I also have hobbies like all men. My hobby is fishing.
I started a personal blog where I share my experience. I try a lot various methods and ways to increase the catch. If interested, you can read. Nothing more, just my personal experience.
Attention, only TODAY!
The Russian model Lada Largus, thanks to its unsurpassed carrying capacity among classmates and enviable spaciousness, has long gained fame among owners not only on domestic market but in other states. This success was facilitated by the presence in the arsenal practical station wagon balanced technical capabilities and decent reliability of most nodes.
To maintain a Lada Largus car with a 16-valve engine, like any other, in good condition, it is necessary to adhere to timeliness when replacing the entire list of consumable components and fluids. Among these positions, a special place is given to oil in the transmission unit. And therefore, many owners are interested in the question of which oil to pour. The manufacturer, for its part, assures that given liquid cannot be replaced until its full resource is exhausted. However, the realities of operation sometimes make adjustments, which implies the need for intervention in the unit ahead of time. In most cases this required action dictated repair work in a box or premature wear, implying complete replacement unit.
How to choose oil?
From the factory line Lada models Largus get off tucked inside transmission unit oil. Its viscosity-temperature characteristic implies compliance with the values \u200b\u200bof "75 W80", and the brand - "Tranself TRJ" from the manufacturer "Elf". Factory regulations prescribe to lean towards the need to check the lubrication level in the transmission after a periodic mileage of 15 thousand km. If it becomes necessary to top up, this action should be carried out only with the specified lubricant.
Changing the oil in the gearbox involves almost 100% draining of the used substance and filling the unit with new oil.
How to check the level and top up?
It is recommended to check the lubrication level in the Lada Largus transmission before replacing or topping up. The control procedure itself is quite simple and quickly implemented. It will require a minimum of skills and such a list of auxiliary tools and tools:
- a syringe that allows you to add liquid;
- rags and a container that can hold about three liters;
- a square key with a size of "8";
- grease, in its type and origin similar to that indicated in our material.
If there is no syringe, then it can be freely purchased at stores specializing in auto products. Here, this device should not be confused with medical supplies, which, of course, are absolutely inapplicable in this situation. An addition can be a hose, which provides easy access to filler neck. After preparing these funds, you can safely proceed to level control and topping up, if such a need arises as a result of the “monitoring mission”.
For control actions, the following algorithm will be optimal.
- We are filming motor protection. Among motorists, this protective part is called the central mudguard.
- We find the drain plug of the box and unscrew it using the designated “square” key.
- Before unscrewing itself, we substitute a container under the hole.
- We estimate the level, which, in accordance with regulatory standards, should be located slightly below the lower edge of the filler neck. When this level is less than the indicated limit, we top up.
- To do this, insert the tip (hose) of the syringe into the filling neck and perform the usual action of squeezing the liquid into the unit.
- We “pump” the box with oil until the return flow of oil through this hole begins. Here we complete the topping up, and carefully wipe the perimeter around the hole with a prepared rag. It remains to tighten the cork, which we do without a share of embarrassment.
- Do not forget to inspect the condition of the sealing ring on the plug. If it is worn out, then we change it. price issue of this important product is scanty (about 10-15 rubles).
Now you can start operating the car, after making sure that the oil in the gearbox is filled and there are no leaks.
Lubricant change
If a regular oil change in the gearbox is not able to bring owner Lada Largus expected result, then you will have to resort to a complete replacement of the lubricant in the transmission unit. This work is also not difficult, so a novice owner can do it.
We use a similar set as a list of tools. Unlike the top-up procedure, here you will need to take care of the presence of the full volume of oil that needs to be replaced. According to the regulatory requirements from the manufacturer, this amount is equivalent to three liters. We also do not recommend experimenting, but using oil in a gearbox that meets regulatory postulates technical guidance.
Stock up on grease to save yourself the hassle of searching and buying the next time you need to top up. Decide which oil is best for your car.
Having prepared all these tools, we perform the following list of actions:
- we install our Lada Largus over the pit (you can also hang it with a lifting tool);
- we prepare a container in which the specified volume of liquid can fit;
- unscrew the plug first on the filler hole, which will speed up the drain process;
- now we move to the drain plug and carefully unscrew it (it is recommended to warm up the box before changing the lubricant);
- drain the liquid, waiting for its complete descent;
- at the end of this moment, we return the plug to its place, not forgetting to replace the seal;
- then we begin the process of filling oil through the neck of the same name; we do this slowly, allowing the viscous oil to gradually leave the cavity of the syringe and fill the crankcase of the unit;
- often it is not possible to drain 100% of the used lubricant, therefore, after filling, not 3 liters are placed, as indicated in the regulations, but a little less;
- we fill the transmission crankcase with “fresh” grease until its return current appears from the hole;
- now it remains to carefully wipe the area of \u200b\u200bthe transmission housing directly adjacent to the filler neck with a rag;
- install the plug in its original place, tightening it with the required torque;
- we start the engine of 16 valves of the Lada Largus car and make a series of gear changes in the box, which will allow the new lubricant to optimally disperse inside the transmission unit (this is important before starting to move, when the gearbox starts to experience a load).
That's all, the gearbox oil has been changed.
Summing up
In practice, it has been reliably established that such procedures as topping up or changing the oil in the gearbox in the Lada Largus transmission with a 16-valve engine are in no way difficult. This allows inexperienced owners to incline without a shadow of a doubt to such repair actions when the need arises. Note that the factory recommends replacing the fluid after a 200,000-mile run, although in reality this interval can be significantly reduced. In any case, control the level and what kind of oil you fill in, that is, its condition (color, smell, presence of chips, etc.) of the oil in the transmission after the scheduled interval, and then you will have full information about a real need for replacement or topping up.
The oil change in the Lada Largus gearbox, according to the manufacturer, should not be carried out until the resource is exhausted. But many motorists do this operation in order to replace oily liquid at a different viscosity or when repairing a gearbox.
To change the oil at the checkpoint on Largus, you will need the same tools as when topping up. That is, the key to drain plug(he is one, a key-square of size 8) and a syringe with a hose for pouring oil into the gearbox.
Oil in the gearbox and a syringe for filling it
So, when you have decided on the tool, you can start working:
Here is not tricky way change the oil in the gearbox Lada Largus.
Oil selection
Since Largus is a colleague of Renault, then it is necessary to pour ELF oil, this is exactly what the AvtoVAZ concern recommends
For gearboxes installed on Largus, it is necessary to fill in oil marked 75W-80. But the oil in the engine differs depending on the number of valves. Details about:
choice of oil for an 8-valve engine
This is stated in the service manual and service book. If necessary, but no later than 15,000 km, it is necessary to check the level and add oil. It comes with a Tranself TRJ from the factory. It is this brand that must be topped up at the checkpoint.
Level check
To complete the operation, you will need some tools, namely: a syringe for pouring liquids into the transmission and a size 8 square key.
Let's get to work:
Now the oil level in the gearbox is in order, and there is no need to worry.
Transmission oil change video
conclusions
An oil change in the gearbox should be done once every 200,000 km.
This is due to the fact that it is through so much that the liquid loses its chemical and technological properties. Thus, it is possible to extend the life of the gearbox by about 50 thousand km.
From time to time, many car owners are faced with the fact that the oil in the gearbox needs to be replaced. Strictly speaking, officially, the AvtoVAZ enterprise, in principle, does not provide for changing the oil in the gearbox in this car.
However, it may be required if the time has come routine maintenance or transmission oil no longer meet its performance requirements.
As for the first case, strictly speaking, officially, the AvtoVAZ enterprise, in principle, does not provide for changing the oil in the gearbox in this car, that is, there is simply no replacement procedure. However, we still recommend changing it every 100,000 km, and we also recommend checking the oil level at least every 15,000 km.
The second case involves changing the oil without waiting for the previously indicated mileage. If you notice that gear shifting began to be carried out without the former smoothness of the gearshift knob, or that from the side of the box began to appear extraneous sounds- this is just the second option.
The latter is supported by:
- Frequent standing in traffic jams ( excessive heating oils)
- Frequent moving over short distances (when the system does not have time to really warm up, resulting in condensation - this especially happens in winter).
In any case, if you suspect any problems with the gearbox, it would be useful to check the oil level.
Of course, you can drive your car to a service station or contact official dealer, where you, of course, will make such a replacement. The cost of such a procedure will cost you from 2 thousand rubles. However, do not rush to spend money - you can easily carry out the procedure for changing the oil in the checkpoint yourself, it does not represent any super-complicated manipulations.
All you need for this:
- Pit or lift
- Special wrench (4-sided) for unscrewing the drain plug
- Wrench 10 to remove the pallet
- Basin or bucket (or other suitable container for draining used oil)
- Hose with funnel (for filling new oil)
- O-ring for drain plug
- Actually, a canister of new gear oil
Step 1: Draining Used Gearbox Oil
Place the car on a lift or drive it into a pit. Using a 10 wrench, remove the pan. There are 6 bolts to remove in total.
Prepare a container for draining the oil, then start unscrewing the oil drain plug with a square wrench. When the plug can be turned more easily, continue unscrewing it by hand and be prepared to quickly substitute the container so that the oil does not suddenly begin to pour out of the box onto the ground.
Wait until the oil has completely drained into the container.
There is a sealing ring under the plug. Most likely, it is badly worn or wrinkled - put a new ring.
