A clutch for an automatic transmission for a motor vehicle includes a clutch housing and a retaining ring. In an inner circumferential surface of the clutch housing concentrically at a central axis (M) of the cylinder jacket-shaped inner circumferential surface, a ring groove that is open radially inward is formed, within which the retaining ring is arranged. The retaining ring is thereby open and features two spaced ends. In the area of the ring groove, at least one stop is formed, whereas a distance between the ends from each other or the position of the stop is selected in such a manner that, in the assembled state, only one end of the retaining ring may come into contact with a stop, while the other end is spaced from this stop or an additional stop.

A transmission parking lock has an actuating rod that is essentially translationally displaceable, which bears an actuating element, and with a locking lever that is essentially rotationally displaceable, bears a locking element For inserting the transmission parking lock through the displacement of the actuating rod, the locking lever is pivotable from a resting position of the same into a locked position in such a manner that the locking element engages in a recess of a gear wheel () allocated to a gear shaft, and with a device that withdraws the actuating element of the actuating rod in the resting position of the same from the locking lever.
