摘要： The invention relates to a motor vehicle having a power train wherein the engine can drive an automatic transmission by way of an automatic clutch. The gear ratio of the transmission is selectable by a first drive and a second drive is employed to shift the transmission into the selected gear. The two drives are mounted on the transmission case by way of a common base plate. Novel kinematic transmission lines connect the drives to the ratio selecting and gear shifting components of the transmission. One of the transmission lines employs a transmission stage, a carrier for translation of rotary movement into axial movement, and an element for transfer of axial movement to the transmission. The translation of movement of the drive in a selection process takes place by way of two transmission stages.
