Each gear shift is triggered by the fully integrated transmission control (VGS). In the process one component group is assigned to each shift operation. One component group consists of the respective control solenoid valve, the regulating valve involved, the responsible shift valve and the necessary multi-disk brake or necessary multi-disk clutch.

The pressure in the engaging multi-disk brake or multi-disk clutch is increased constantly and simultaneously the pressure in the disengaging multi-disk brake or multi-disk clutch is reduced. In the process a flowing transition is involved, but nevertheless the components affected are actuated directly and as a result enable downshifting via several gears.
