Oil change in a variator of the car

Until recently, cars with CVT transmission in the markets of our country were few. Today the situation has changed. There are such cars, there are quite a few models. And their owners are interested in how the oil is being changed in the variator box. This process is not very complicated and slightly similar to the same operation on ordinary automatic transmissions.

Features of variator transmissions

Auto, equipped with automatic transmission of this type, can work in a softer mode. Thanks to the features of the transmission, the car speeds up faster, and fuel consumption, compared to traditional automatic and mechanical boxes, is much lower. Naturally, for effective work, this mechanism must be regularly and carefully serviced. Specialists recommend to carry out maintenance every 50 000 km. Oil change in the variator should also be carried out with such periodicity.

Variatory transmission provides several maintenance scenarios. This is the performance of all work in the SRT or the implementation of the operations themselves. With regard to the replacement of hydraulic and lubricating fluids, then distinguish between full replacement and incomplete.

We change the liquid partially

If you do not completely perform this operation, you need to do a few simple steps. For work you need a lift or a flyover.

The first stage involves lifting and leveling the machine horizontally. Then you should substitute a container of suitable dimensions under the transmission tray. Now the cork is unscrewed, and the lubricant drains into the container. Give it to her. Then tighten the plug and fill the housing with oil. For this it is recommended to remove the left front wheel. After that you can see the filler hole. Oil change in a variator is made in that volume in which the old means has been merged.

This method allows to update or top up the lubricating transmission fluid by about 40% of the volume. To complete the replacement in full, you should perform this list of actions about 5 times. The gap between operations is approximately 500 km.

After implementing these actions, experts advise to thoroughly wash the filters, the pallet, as well as the gearbox mechanism.

Independent oil change in the variator

To car can long please its owner, you need to constantly look after its nodes and units. You should constantly monitor how individual mechanisms work. If necessary, replace parts in time. Technical fluids in automatic transmissions of variator type also do not tolerate delays. The old grease may not have the best effect on the work of the parts.

To make a replacement yourself, you will need a suitable tank size, a set of standard garage tools, a new gasket from the pallet, filters, gloves. Naturally, you need to acquire a new tool.

Stages of work

Self-replacement oil in the variator provides a pit, trestle, lift and horizontal position of the machine. If you were driving a car, muffle the engine and let it cool for about 4 hours. During this time, all the lubricant will drain into the automatic transmission tray. Place a pre-prepared container under the drain plug and unscrew it. Wait until the entire volume flows out, and then unscrew the measuring tube. So you can completely get rid of the old grease.

Using the keys, unscrew the oil pan sump mountings and remove it. As a result, you will get access to the oil filter - remove residual oil and sediment at the bottom of the oil pan. Next you need to dismantle and thoroughly clean the magnets, as well as the filter.

Now you can remove the hydraulic unit. To do this, disconnect the solenoids, twist the 14 bolts. Do not forget to mark the bolts - this will simplify the assembly. Carefully remove the hydraulic unit. It's best if you put it in another container.

Then remove the second filter. To do this, you need to unscrew the 10 bolts. They connect the unit - it will split in two. Do not overturn these parts, otherwise the springs will fall out. You reached the filter - replace it immediately. Then assembly. Collect the same as disassembled. Prepare to the fact that when disassembling, about 2 liters of liquid drain off.

Install a new gasket on the pallet, install an external filter and the pallet itself. Be sure to check how the variable speed pulley and the hydraulic unit cylinder are combined. This can be done from the salon. To do this, manipulate the gear selector.

Directly changing the oil is done through the filler hole behind the left front wheel. The volume of the filled liquid is checked with a feeler gauge.

Nissan with CVT variators

Such boxes are often found among the cars of this manufacturer. These automatic transmissions are reliable, and with proper care can last a very long time. The main thing is to make sure that the work is done on time.

When it is necessary to replace the oil in the variator "Nissan"?

The proximity of the replacement is diagnosed by color. If the liquid has darkened or at it has appeared atypical smell, it is a signal that it is necessary to change oil immediately.

A timely operation allows you to significantly extend the life of this node. As for the periodicity, the manufacturer recommends that such service be performed after 30,000 km.

"Cascais"

Let's look at how the oil of variator "Nissan Kashkai" is being changed. To service the variator, you will need a set of standard tools, a pallet padding, a slotted screwdriver, a funnel, rags.

All actions can be done by themselves. As for the volume of oil, you will need 2 cans of 4 liters. The first thing the car is installed on the pit. Before replacing, the crankcase protection must be removed. Then unscrew the two bolts. Now remove the 4 pistons from the sides. When you are in the motor department, it's time to start the procedure. First of all, check the oil level. This can be done with a feeler gauge.

If oil change in the variator ("Kashkay Nissan" is not an exception) is necessary, then start the engine and warm up the motor. Then remove the machine from the gear. Remove the dipstick from the pipe. Now you can drain the old liquid. The whole process of draining will take no more than 30 minutes.

Pour in a new tool with a funnel, and then look again at the level change.

"Toyota"

How does this car change the oil in the variator? "Toyota" is repaired in the same way as described above. It is necessary to remove the protection of the motor, as well as the left wheel, put the automatic transmission in position N, turn off the wheel arch liner and remove the filler. Fill the manufacturer's recommended volume.

Naturally, before this drain the old oil. Then you tighten the plugs and it's done.

Honda

How is oil change made here? Honda can also be repaired by hand. So, on such cars mechanisms of the first and second generation, and also variators of type Fit are established. And if the first and second are serviced as CVT, the maintenance of the Fit systems is exactly the same as if you were working with an ordinary automatic transmission.

Replace the two filters. Depending on the modification, the filters may be different. Also, the pallet should be cleaned, the gasket replaced, and the control unit cleaned. A new liquid is poured through the funnel. Do not forget to check the probe level from time to time.

Mitsubisi

Replacing the oil in the variator ("Mitsubishi Lancer", among others) is similar. Here, too, the tray is removed, the old liquid is drained. It takes about 40 minutes to drain. During this time, about 6 liters of variator fluid will flow out. After that, the cork is twisted.

Use a new watering can to fill as much as drained. It is important. Then start the car and work the gears. Repeat the procedure about 7 times. This is necessary for the outlet of the waste liquid from the torque converter. It will be updated. Silence the car and drain the second batch.

Oil change involves the installation of new filters. Twist the drain plug. Pour in the freshly drained liquid. Start the engine again, operate the selector and check the level. That's all!
