A power train controller and control method are provided for a passenger car driven by a combustion engine and an automatic gear changing transmission. Control sensors detect a current operating state of the passenger car. Three different modes of operation, including sports mode, economy mode, and comfortable mode are selected by the driver. Depending on the selected mode, the automobile transmission is controlled in different shifting patterns as a function of the sensed vehicle operating conditions.
