Instructions for changing the oil in the Lada Largus gearbox

The joint production of AvtoVAZ and Renault equipped Lada Largus cars with five-speed gearboxes. Depending on the configuration, gearboxes marked JR5 and JH3 are installed.

On more common versions with a 1.6-liter 8-valve engine and a 1.6-liter 16-valve engine, a JH3 manual transmission is installed.

The maintenance regulations do not provide for changing the oil in the Lada Largus gearbox. Although cars are adapted for harsh operating conditions, it is recommended to carry out lubricant diagnostics every 15,000 km.

This is done using a visual inspection. It is enough to unscrew the filler plug at the end of the box closer to the cooling radiator.

Causes and signs of oil losing its properties

If the transmission fluid is darkened or black in color, this may indicate that the lubricant has undergone a chemical change as a result of severe contamination with wear products of the gearbox elements (gear shafts and synchronizers) or a violation of the tightness of the gearbox (moisture and dirt entering through the seals of the drives or input shaft ).

The smell of burnt oil in Lada Largus. May indicate insufficient lubrication levels due to leaks. Under heavy loads on the unit, cooling of the rubbing parts is not adequately ensured.
If shifting gears is difficult, you may hear some noise or hum at certain speeds or when idling. The lubricating properties of the transmission fluid are partially lost or the level in the gearbox housing is insufficient.
Increased wear of gearbox elements. Aggressive driving style and incorrect gear shifting.
Mileage over 60,000 km since previous replacement. It is at this interval that service stations recommend replacing the transmission fluid.

What kind of oil to pour into a manual gearbox Lada Largus

Lada Largus is the best-selling Russian station wagon. Good driving characteristics, a spacious interior, high comfort and reliability - all these qualities made the car popular even on the secondary market. The simple design allows you to maintain the car yourself, and thereby save on repairs. So, during self-service, one of the most popular procedures is not only replacement, but also selection in the gearbox. Any motorist can handle this. And yet, even experienced car enthusiasts may have questions about this. In this article we will take a closer look at how to choose the right oil for a Lada Largus manual transmission.

Let's consider the criteria for choosing transmission oil for Lada Largus. The question of choosing a suitable lubricant for a manual transmission usually arises after 15-20 thousand kilometers, when it is time to change the fluid. The Russian station wagon is equipped with two types of gearboxes – JH1 (for a 1.4-liter engine) and jH3 (for a 1.6-liter engine). Both boxes have a certain clutch housing size, and all other characteristics are absolutely similar. But despite this fact, the two gearboxes support the same oil with identical parameters, which will be discussed later in the article.

Oil selection

The manufacturer uses transmission lubricant ELF TRANSELF TRJ 75W-80 (No. 194757) or 75W-90 (No. 195286).

Good analogues include Casrtol Syntrans Transaxle 75W-90 and Motul Gear300 75 W-90. All of the listed oils have the necessary API specification tolerances: GL - 4. They have high lubricating and detergent properties.

The use of lubricants for a Lada Largus car with a different approval is not recommended. A different additive package may affect the functional qualities of soft metal box elements (synchronizers).

Semi-synthetic lubricants, for the most part, have mineral substances, some synthetic substances and a certain percentage of additives responsible for enhancing the properties of oils.

Synthetic fluids are based only on synthetic substances. Produced from hydrocacking substances with the addition of additives.

Synthetic gear lubricants have better characteristics than semi-synthetic ones, but are more expensive.

The choice of oil viscosity depends on the climatic operating conditions of Largus. Thicker lubricants have proven themselves to be excellent in hot conditions. Technical fluids with lower viscosity require less time to warm up in sub-zero temperatures.

I changed mine at about 24,000 km, everything was fine before, after the replacement, I can say that the gears immediately began to turn on poorly, that is, worse than before. Now the mileage is 39,000 km, sometimes it is impossible to turn on the first one, I turn it on through the second one. If the first one does not turn on, then I turn on the second one and quickly start the first one. The remaining gears are engaged but with noticeable resistance. I suspect underfilling of oil. I remember when I was changing it, I drained about 2.5 liters, but only filled in 2, it didn’t fit anymore, but somehow I didn’t attach much importance to it, I took 5 liters, I thought that if something else then I’ll add more. Then, long after the replacement, I accidentally watched a video where it turns out that it seems necessary to jack up the left side of the car and then the oil will fill completely. I recently bought 3 liters of fresh one, I’ll be changing it again soon. The 3 liters that I had left from the last replacement went to the chainsaw)))

Let me know when you change it again. I filled it to the level until it leaked out of the filler neck. The car was parked on a level surface

Mine was also level, I filled it until it started leaking. I'll definitely let you know. Subscribe to my car, and then you will see my blog entry in your feed. I will most likely do a report next week, I will finish the repairs in the garage.

Step-by-step instruction

Changing the oil in the box is carried out on a well-warm-up car.

Important! The temperature of the transmission fluid in the box of the Lada Largus should be 60 degrees. It is determined by a special device - a scanner. If this is not the case, the car warms up to the operating temperature of the internal combustion engine. The gearbox lubricant temperature will correspond to 60 degrees. This will facilitate good oil drainage. Fig 3

For access and convenience, we drive the car onto an overpass or inspection hole.
Apply the parking brake.
We turn on the transmission.
We go down into the inspection hole and remove the engine protection. Six 10mm bolts.
Unscrew the plastic filler plug by hand. Using a special four-sided wrench, remove the drain plug.
Drain the oil into the prepared container. If there were no leaks, we get approximately 2.5-2.8 liters of waste. The full volume of 3.1 liters cannot be drained due to the design features of the upper row of gears.
We replace the sealing washer with a new copper or aluminum one.
We wipe the drain neck with a rag and screw the clean plug back on. Tighten with a force of 30 Hm. We use a torque wrench. If there is no key, tighten the wrench tightly enough to avoid possible oil leaks. But not too much, so as not to spoil the edges and break the thread.
Using a syringe, fill in new transmission fluid through the filler hole. If you don’t have a syringe, take a hose with an outer diameter of no more than 16 mm and a funnel. Open the hood of the car and, through the top, insert the hose into the filler neck.
Fill with oil until grease flows out of the same hole. The filler hole is also a control hole. The lower level, which is the norm. Before tightening the filler plug, inspect the sealing rubber for integrity.
If necessary, to eliminate smudges, replace the rubber band or plug assembly with a new one. We start the car for a few minutes. Then we inspect the gearbox for oil leaks.
Reinstall the engine protection.
To carry out work on replacing the gearbox lubricant of a Lada Largus car, you can turn to professionals or do the work yourself.

Checking the level and topping up

Before changing or adding lubricant, you should check the oil level in the box. This is not as difficult to do as many may think. If you have minimal experience and skills, you can easily cope with the task with your own hands. In the case of a Lada Largus car, for work you will need to take:

a syringe that will be used to add the missing liquid;
rags;
an empty container for several liters;
key square for 8;
oil similar to what is in the box.

Special syringes are used, available in auto parts stores. Do not confuse them with medical syringes, which are not suitable for such purposes. Special topping and filling tools have a hose that allows easy access to the filler neck. When everything is ready, you can begin to assess the amount of oil in the box and add the missing amount of lubricating fluid to the Largus gearbox.

The work is carried out according to the following algorithm of actions:

Remove the engine protection. People often call it the central mudguard. The essence does not change from the name. Find the filler plug, which can often be easily unscrewed with a square wrench. Before opening the cap, place an empty prepared container under it to avoid spilled puddles of oil. According to the standards, the level should be located slightly below the filler hole. If it is less, then you will need to add the missing amount of gear lubricant. A syringe pre-filled with oil is inserted into the filler neck. Gradually pour in the viscous liquid. At some point, lubricant will begin to flow through the hole.

Wait until it stops running completely, then wipe everything with a rag and screw the plug back into place. During the process of checking and topping up, pay attention to the condition of the rubber O-ring on the plug. If the machine is used for a long time and actively, the ring may wear out

It is better to replace it immediately, since a worn seal will break the seal and the oil will gradually leak out. Such a ring costs about 5 - 10 rubles, so serious expenses for such repairs will not be required.

If you did everything correctly, the oil is not leaking anywhere and the gearbox is functioning normally, then the transmission fluid level is sufficient and you can continue to operate your car.

When is it necessary to change transmission fluid?

To avoid serious gearbox problems, you should monitor the oil level. Also, pay attention to its condition. It should not have an unpleasant odor or metal shavings. A scheduled check of the transmission should occur every 15,000 km.

The danger of operating the Lada Largus is caused by engine tripping. The main reason for this is the use of inadequate quality oil. The machine must be subject to full professional diagnostics in a specialized service center.

Premature replacement of the transmission fluid is possible if, during operation of the Lada, extraneous noise appears and the gears do not work well. If you have difficulty shifting gears, you also need to check the oil level in the manual transmission of your car.

Thus, Lada Largus is a car that can be used for commercial purposes. The car may have a 1.6 liter engine. The transmission is set to “mechanics”. In some cases, it is possible to solve the problem of the functioning of the high-speed gearbox by replacing the transmission fluid.
