Transmission oil protects the rubbing mechanisms and the surface of the gearbox from wear, effectively lubricating them. In addition, it reduces the mechanical load on the nodes, removes heat and removes microparticles, which are formed as a result of wear or corrosion of parts. Thanks to him, riding a car becomes comfortable and smooth. How to replace oil in the gearbox on Chevrolet Lacetti - read further in the article.

Automatic transmission, why pour oil into the gearbox

Automotive transmission is a complex unit consisting of a large number of moving elements. In the process of work, they are heated, since elevated friction occurs between them.

In addition, oil in automatic transmission is an additional working organism that transmits to the planetary transmissions torque.

Lubricant for automatic transmission consists of a package of additives and a basic basis. In the process of work, the initial properties of oil are gradually lost - additives are produced and the protection of transmission elements is deteriorated. When the car works, the temperature inside the automatic transmission reaches +50 degrees Celsius. In such conditions, the old lubricant with spent additives foams and lubricating properties.

Transmission, how often it is necessary to change the oil and what signs will indicate the need to replace the oil

Exhaust oil in automatic transmission can not create on rubbing elements (washers, bearings, bushings) protective film.

The transmissions are turned on fuchlessly or turn off spontaneously, the basic transmission and soles of the differential occurs, fails the transmission. The foamed oil in the gearbox prevents the transmission of torque, as a result of which the vehicle simply stops moving.
