Experts recommend changing the oil in the Nissan X-Trail T31 and T32 variator every 50-60 thousand km. However, many motorists make replacements even more often: after 40 thousand kilometers traveled.

Consumables

During the repair process we will need materials and tools such as:

original NISSAN CVT NS-2 lubricant specifically for Nissan X-Trail T31. In the catalog its number is KLE5200004EU. For the later model X-Trail T32, NS-3 grease must be used;
two filters: one coarse filter (32101EE), the second fine filter (2824A006);
gaskets that are necessary for the variator pan (313971XF0C), as well as for the oil cooler (number 2920A096);
a lot of rags and a container where the used lubricant will be drained (the container must have a volume of at least 8 liters).

Preparation for work

Before you start changing the oil, professionals recommend warming up the car's gearbox. For this purpose, you need to drive 1 - 2 kilometers, then you can start working.

You need to start by jacking up the front of the car and removing the driver's side wheel.
The fender liner is being dismantled. It is important to note here that the fender liner is not removed completely, but only to the middle in the direction from the front bumper. Dismantling is carried out according to a simple scheme, since the fender liner is held in place by pistons and a hex bolt (1 piece). To operate, you will need a T20 star key. By removing the fasteners, the fender liner can be moved to the side.

Engine protection removed

Once access to the Nissan X-Trail pan is open, you can begin to remove it. The engine protection consists of two parts: plastic and metal.

First, the plastic protection is removed. This action is carried out quickly, since the fastening is carried out on 4 snap-on pistons. Removing metal protection will take more time and physical effort. The fastening here is made with metal bolts (4 in total), which are advisable to unscrew in a certain order:

First, the bolts located next to the front bumper are completely unscrewed;
the two rear bolts are unscrewed by half (simply loosened);
the mortgages are removed very carefully;
the rear bolts are completely unscrewed.

Attention! If the rear bolts are removed first or second, bypassing the “loosening” stage, then the embedded parts will definitely move along the beam. This will create unpleasant circumstances: you will have to jack up the rear of the car, which will slow you down in time.

Step-by-step instruction

We drive the Nissan X Trail T31, turn it off and take all the necessary precautions: activate the handbrake, install wheel chocks under the rear wheels.
Use a wheel wrench to remove the wheel nuts of the front left wheel and jack up the car until there is a gap between the wheel and the ground. We remove the wheel. We put it under the left threshold as insurance in case of absence of racks.
We dismantle the fender liner, which is held on by several plastic pistons and one bolt. The caps are reusable, remove them carefully. You can do without completely removing the fender liner. It is enough to bend the part from the bumper to the middle of the wing. This will be enough for unhindered access to the oil separator. All this is necessary when replacing the fine filter.
Changing the oil in the variator is not possible without removing the engine protection. We go down into the pit and dismantle the engine protection, of which there may be two. First of all, remove the plastic one. It is held on by several plastic clips. Next, remove the metal protection, paying attention to the following recommendation.

The total oil volume in the Nissan X Trail T31 box is 7.5 liters. The volume of the canister with the original oil is 4 liters (Nissan¬ Kle5200004 EU).

Good analogues include Ravenol oil (4014835719392). Fill about 6 liters of fresh lubricant through the dipstick hole. Then we bring it to normal in small portions, monitoring the level with a dipstick.

Once the required amount of lubricant has been achieved, start the car and switch the gearbox selector alternately to all positions. We turn off the car and check the level. If necessary, add or pump out oil using a technical syringe.

Selecting the right crankcase and disassembling it

After removing the car pan, the CVT housing and the engine crankcase come into view. How to understand which of the two crankcases belongs to the variator? The one we need is installed to the left of the muffler along the path of the car. The engine crankcase is installed in front of the variator and will not be used during operation.

For ease of operation, the variator must be cleaned of dirt. This is where WD-40 comes to the rescue. After treatment with the product, wipe the body dry with a dry cloth. After which it becomes perfectly clean, and therefore suitable for further work.

On a clean variator housing you can easily find a plug for draining the lubricant. It is difficult not to notice, as it is the largest in size. Prepare some container in advance where the old used lubricant will be drained. The drain plug has a tight grip on the threads, so reinstalling it will be difficult. She will need some physical effort.

As soon as the waste has drained, the plug is put in place and the removal of the crankcase protection begins. A #10 socket wrench will be used in this procedure. You need to be extremely careful when removing the housing. It is important to hold it with your hand to prevent it from falling. After draining, about 150 ml of old oil will still remain in the system, which also needs to be drained into a container prepared in advance for this purpose.

Whenever changing the lubricant in the gearbox, it is always necessary to simultaneously replace the filter.

Description of the variator

The second generation of the X-Trail crossover was equipped with Jatco RE0F06 CVTs, as well as modified RE0F10A (JF011E) gearboxes. CVT transmissions used in designs have the following advantages:

the simple design of the box allows the motorist to independently diagnose and maintain the system without the need to involve specialists.;
the ability to remove filters and clean them of dirt;
magnets installed in the tray attract wear products (metal shavings);
When starting the engine, there is no need to warm up the liquid. The system will automatically bring the oil to operating temperature;
low gearbox wear;
a radiator built into the system allows you to maintain the temperature of the variator within normal limits and protect against overheating;
the absence of steps in CVTs ensures lower consumption than on a standard automatic;
smooth acceleration of the car;
simple controls;
CVTs are relatively safe for the environment.

There are some drawbacks, among which it is customary to highlight:

improper operation very soon leads to serious disruptions in the operation of the CVT variator;
expensive maintenance and repairs;
The failure of one sensor leads to the inoperability of the entire system.

Replacing or washing the filter

Three bolts that secure the filter are removed from the variator housing with magnets. Then the latter is slowly pulled down so that the rubber rings are not damaged. The remaining oil will leak out of the filter.

The filter and magnets can be washed with WD-40, then blown out. After cleaning, the magnets and filter are installed in their original place. The crankcase is tightened with bolts.

It will take no more than one hour to change the oil in the Nissan X-Trail gearbox.

Assembly Features

The assembly process is simple, but has some features:

The bolts should be tightened “crosswise”, as is done when installing the cylinder head. At the same time, you should not overdo it with the tightening force.
When installing the variator protective pan, it is better to replace the old gasket with a new one.
Sometimes technicians forget to replace the drain plug and tighten the oil cooler bolts. This nuance should always be remembered.
To install a new filter, you will need to tilt the oil cooler housing to the side. But you can remove it and rinse it well with diesel fuel.
You should calculate how much lubricant is poured into the container during disassembly (usually about 7 liters). This volume needs to be known exactly in order to pour the same amount back. The amount of infused oil should not exceed the permissible limit. Excess may push the seal out.
Fresh lubricant flows into the gearbox through the dipstick.
