Abstract:
A vehicle transmission having a housing (5) with a region in which a connection plate (7) can be firmly attached. The connection plate includes areas for receiving at least parts of the actuating elements, which actuate the torque-transmitting components, and/or parts of the actuating elements, which actuate a transmission shifting device. At least one required actuating cylinder (3) is formed by a first cylinder part, that is located within the connection plate, and a second cylinder part, that is located within the transmission housing. A stop ring (10), provided in the cylinder (3), is configured in such a way that the sealing contact surfaces of a piston (2), in the transmission housing and/or the connection plate, are formed by a bushing-shaped expansion (10′, 10″) of the stop ring (10).
