A piston for a gear-change selector module of a gearshift has a piston body, at least one sealing element, and a cap which is attached to the piston body by means of a clip connection. Furthermore, the sealing element is here attached to the piston body by means of the cap. Also a gear-change selector module with a piston, and a method for mounting a piston, are provided.

Piston, gear-change selector module and mounting method

A piston, in particular for a gear-change selector, including a piston body with a piston skirt and with a piston end face which can be pressurised with a working fluid. The piston includes a first sealing portion and a second sealing portion. The piston body and the first sealing portion have mutually complementary geometries so that they form a first vent channel. The first vent channel is arranged in a hydraulic series circuit with the second sealing portion. The second sealing portion prevents venting up to a first pressure and allows this above the first pressure. The invention furthermore concerns a gear-change selector and a gearshift for a vehicle.
