The kik-Down device (the device of compulsory anticipatory switching on lower transfer) provides maximum on these traffic conditions car acceleration. As soon as pressure upon a pedal of an accelerator will exceed a certain threshold value, depending on frequency of rotation of the engine and speed of movement there is a switching on one of lower transfers. Return switching on the next higher transfer will follow only when the most admissible value of frequency of rotation of a cranked shaft will be reached.
