On Mercedes-Benz cars establish 4-or 5-step automatic transmissions.
The automatic box consists of the hydrotransformer, an epitsiklichesky tooth gearing, and also coupling and brakes with a hydraulic drive.
The torque from the engine to a transmission is transferred via the hydrotransformer which carries out function of liquid coupling and operates as automatic coupling, also provides torque transfer at acceleration.
The Epitsiklichesky tooth gearing provides advance on one of four or five transfers or movement by a backing. Components of a tooth gearing cope brakes and couplings of coupling which are put in action hydraulically. The pump located in a transmission, provides necessary hydraulic pressure for work of brakes and the coupling coupling.
Management of a transmission is made by the lever of the selector and two switches. Situation D provides an automatic choice of one of four or five transfers. The automatic mechanism of compulsory inclusion of a low gear of KICK DOWN compulsorily switches transfer to the lowest if the pedal of an accelerator is pressed against the stop. This mode is necessary for using, when the maximum acceleration of the car is required. If the lever of the selector is in situation 3, the car will move only on the first three transfers, and in situation 2 - only on the first two transfers etc. Installation of lower transfers is desirable when braking by the engine, at movement from biases or for prevention of an undesirable choice of the highest transfer on twisting roads.
By means of additional switches it is possible to establish two modes of movement: economic (Е) or standard (S).
Because of complexity of an automatic transmission any repair should be made at service station.
