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

Features of CVT transmissions

Cars equipped with this type of automatic transmission can operate in a softer mode.

Due to the features of the transmission, the car picks up the required speed faster, and fuel consumption, when compared with traditional automatic and manual transmissions, is noticeably lower. Naturally, for effective operation, it is necessary to regularly and carefully maintain this mechanism. Experts recommend maintenance every 50,000 km. CVT oil should also be changed at this interval.

Variable transmission provides several service scenarios. This is the execution of all work in the service station orcarrying out operations independently. As for the change of hydraulic and lubricating fluids, a distinction is made between complete replacement and incomplete replacement.

Change the fluid partially

If it is necessary to perform this operation incompletely, then for this you need to do a few simple steps. To work, you will need a lift or overpass.

The first step involves lifting and leveling the machine exactly horizontally. Then you should substitute a container of suitable size under the gearbox pan. Now the plug is unscrewed, and the lubricant flows into the container. Let her run. Then tighten the plug and fill the body with oil. To do this, it is recommended to remove the left front wheel. After that, you will be able to see the filler hole. The oil change in the variator is carried out in the volume in which the old agent was drained.

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

After carrying out these steps, experts advise thoroughly washing the filters, pan, and gearshift mechanism.

Self-change oil in the CVT

In order for the car to please its owner for a long time, you need to constantly take care of its components and assemblies. You should constantly monitor how the individual mechanisms work. If necessary, replace parts in a timely manner.

Technicalfluids in automatic transmissions of a CVT type also do not tolerate delays. Old grease may not have the best effect on the performance of parts.

To make a DIY replacement, you will need the appropriate size tank, a set of standard garage tools, a new pan gasket, filters, gloves. Naturally, you need to purchase a new tool.

Stages of work

Self-changing oil in the variator provides for a pit, a flyover, a lift and a horizontal position of the machine. If you have driven a car, turn off the engine and let it cool for about 4 hours. During this time, all the grease will drain into the automatic transmission pan. Substitute a previously prepared container under the drain plug and unscrew it. Wait until the entire volume has flowed out, and then unscrew the measuring tube. So you can completely get rid of the old grease.

Using the wrenches, unscrew the fasteners of the oil pan and remove it. As a result, you will gain access to the oil filter - remove oil residue 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, turn off the solenoids, twist 14 bolts. Don't forget to mark the bolts - this will make assembly easier. Carefully remove the hydraulic unit. Best if you put it in another container.

After that, remove the second filter. To do this, you need to unscrew 10 bolts. They connect the block - it will split in two. Do not turn these parts over or the springs will fall out. You have reached the filter - immediately replacehis. Then assembly. Assemble in the same way as disassembled. Prepare for about 2 liters of liquid to drain during disassembly.

Install a new gasket on the sump, install the external filter and the sump itself. Be sure to check how the variator pulley and the valve body cylinder fit together. This can be done from the salon. To do this, manipulate the gear selector.

Direct oil change is performed through the filler hole behind the left front wheel. Check the volume of liquid filled with a dipstick.

Nissan with CVTs

Such boxes are quite common 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 carried out on time.

When is a Nissan CVT oil change necessary?

Proximity of replacement is diagnosed by color. If the liquid turns dark or has an atypical smell, this is a signal that the oil needs to be changed urgently.

A timely operation can significantly extend the life of this node. As for the frequency, the manufacturer recommends performing such maintenance after 30,000 km.

Qashqai

Let's look at how the Nissan Qashqai variator oil is changed. To service the variator, you will need a set of standard tools, a pan gasket, a slotted screwdriver, a funnel, and rags.

All actions can be done by hand. As for the volume of oil, then youYou will need 2 canisters of 4 liters. First of all, the car is installed in the pit. Before replacement, the crankcase protection must be removed. Then unscrew the two screws. Now get 4 pistons from the sides. Once you've arrived at the motor department, it's time to start the procedure. Check the oil level first.

This can be done with a feeler gauge.

If an oil change in the CVT (Qashqai Nissan is no exception) is necessary, then start the engine and warm up the engine. Then take the car out of gear. Remove the dipstick from the pipe. Now you can drain the old fluid. The entire draining process will take no more than 30 minutes.

Fill up the new product with a funnel, and then look again at how the level has changed.

Toyota

How is the CVT oil changed on this car? Toyota is repaired in the same way as described above. It is necessary to remove the motor protection, as well as the left wheel, put the automatic transmission in position N, bend the fender liner and remove the filler plug. Fill with manufacturer's recommended volume.

Of course, before that, drain the old oil. Then tighten the plugs - and the job is done.

Honda

How is an oil change (CVT) done here?

Honda can also be repaired by hand. So, on such cars, mechanisms of the first and second generations, as well as CVTs of the Fit type are installed. And if the first and second are serviced as CVT, then the maintenance of Fit systems is exactly the same as if you were working with an ordinaryAutomatic transmission.

Replace two filters. Depending on the modification, the filters may be different. You should also clean the pan, replace the gasket, clean the control unit. New liquid is poured through the funnel. Remember to check the level with the dipstick from time to time.

Mitsubishi

Change the oil in the variator ("Mitsubishi Lancer" including) is performed in the same way.

Here the pan is also removed, the old liquid is drained. Draining takes approximately 40 minutes. During this time, about 6 liters of CVT fluid will flow out. After that, the cork is twisted.

With the help of a new watering can, pour as much as was drained. It is important. Then start the car and work in gears. Repeat the procedure about 7 times. This is necessary for the exit of the waste fluid from the torque converter. She will be updated. Turn off the car and drain the second batch.

Oil change involves the installation of new filters. Screw in the drain plug. Refill with freshly drained fluid. Start the engine again, operate the selector and check the level. That's it!
