ABSTRACT:
An actuating device for a transmission of a motor vehicle has a housing and two pistons moveably arranged in the housing. A coupling part is arranged between the two pistons and is acted on by the two pistons so as to be moved by the two pistons. The coupling part is connected to a shifting part of the transmission and is made, at least on a surface of the coupling part, of wear-resistant material. The two pistons are loosely seated on the coupling part so that these parts can align themselves properly relative to one another after mounting.
