Zusammenfassung:	A parking lock includes a locking pawl (2) and an interlocking element (6) arranged on a connecting bar (5) to a selector lever (4). The end of the connecting bar (5) facing away from the interlocking element (6) is articulatedly connected to the selector lever (4). A hydraulically actuatable actuator (10) includes two pistons (11, 12) provided for disengaging the parking lock. During normal operation, a detent device (13), which is actuatable by an electromagnet (13a), locks the first piston (11) in a piston position corresponding to an engaged condition (P_ein) or a disengaged condition (P_aus). Without requiring activating the electromagnet (13a) to release the detent device (13), the parking lock, during normal operation, is manually disengagable with an emergency disengagement device (15) acting upon the second piston (12) and is manually engagable with an emergency engagement device (16) acting upon the detent device (13).
