On numerous automotive forums is very common is the view that the service life of the continuously variable transmission is little more than a hundred thousand kilometers. Believe it or not such a statement – especially individual case, but still the CVT is a very complex mechanism and requires careful and timely care. So, choosing a used car equipped with a CVT, you should not rush into buying. First we need to know more about the technical condition of the vehicle.


It is no secret that on the odometer of each car standing on the market neat, straight rows, specified is not the real mileage. This implies that the odometer reading never should be trusted, despite the fact, when buying a used car with a CVT.

We must remember that in the automotive market miracles do not happen and the seller is not a good magician but a person who is capable of any trick, but to get to give unsuspecting and inexperienced buyer documents on a faulty car.

Fortunately, the newer the car the harder it is to conceal its actual mileage, because the mileage is saved in a special electronic control unit, which is equipped vehicle.

Engine operation and oil condition

In order to ensure good vehicle with a continuously variable transmission, you should listen to the sound of the motor. When you test in, the car has to move smoothly, and the speed dial without jerks and suspicious noises. The presence of sounds uncharacteristic for a running engine may indicate the wear of specific parts. Ideally, a sound running engine should resemble the noise of a powerful fan.

It is important to know that a car with a CVT designed for a relaxing and not too fast driving. Sharp braking and fast driving on rough roads, can significantly reduce the service life of the continuously variable box.

Check the oil in the CVT – another important point in the diagnosis of the car before you buy. Be aware that the color of the oil should not be dark and should not have a pronounced smell of burning. Checking oil should be done in two modes – with the engine running and when off.

Alternatively, in order to check the condition of the oil in the variator, it is possible to use a thick, white sheet of paper. Causing a few drops of liquid on paper, you need to check the presence of dark dots or lumps. If any, it indicates that the oil in the variator had not changed.
