ABSTRACT:
A control system for an automatically shifting transmission is described. A direct upshifting or downshifting starting from the automatic mode is permitted, by using a corresponding programming of the electronic control device when a certain selecting device is operated, without transition into the manual mode taking place. A gear change following this upshifting or downshifting is implemented, corresponding to the shifting logic of the automatic mode. In the case of a multiple operation, multiple direct upshifts or downshifts can also be permitted, without leaving the automatic mode.
