Abstract
A shifting device () for shifting a motor vehicle transmission with a shift selector shaft on which a plurality of shift elements () such as shift forks or shift rockers () are arranged and can be displaced to carry out a shifting operation. The shifting device () includes one hydraulic shift cylinder (), that can be actuated from both sides, with a piston () that can be displaced within a cylinder housing () and which is actively connected with a shift element () to be actuated. To simplify a shifting device () of this type, the piston () has a piston rod () that follows the movement of the piston () and can be connected directly to the shift element () in a detachable manner.
