This allows you to make repairs quickly.

The Most frequent reasons of failure of the CVT can be a depressurization of the hull, mechanical wear of moving parts of the transmission due to improper choice of oil. Also the CVT may be damaged due to improper operation of vehicle (off-road driving, transporting cargo, slip, etc.).

Bearing

The Repair box variator “Nissan Teana” is most often required because of the deterioration of the bearings. In this case, there is a hum and a high noise level during operation of the vehicle. If you operate a vehicle correctly, the first manifestation of this fault can be observed after 55-60 thousand kilometers.

Bearings are destroyed for several reasons. Particlesmetal, which are formed by the wear of moving elements, comes into contact with the friction surfaces of the gearbox. This leads to scratching, mechanical damage. In this case, you need to choose the right oil and change it no later than 60 thousand kilometers.
