Claim:
An automatic transmission parking lock comprising: a parking lock gear affixed to a transmission output drive, an elongated lock member ( 2 ) that is longitudinally slidable in a direction along a longitudinal axis of the lock member ( 2 ) and that can be selectively brought into engagement with the parking lock gear when the transmission is placed in a parking position, a lock member spring ( 3 ) engaging with the longitudinally slidable lock member ( 2 ) to resiliently bias the lock member ( 2 ) to counter engagement of the lock member ( 2 ) with the parking lock gear, an arrester ( 7 ) movable in a direction substantially perpendicular to movement of the lock member ( 2 ) and engaging with the lock member ( 2 ) to non-resiliently restrain the lock member ( 2 ) from engagement with the parking lock gear when the transmission is in a position other than the parking position, and when the transmission is moved into the parking position, an activation element ( 13 ) engages with the arrester ( 7 ) and disengages the arrester ( 7 ) from the lock member ( 2 ) so that the lock member ( 2 ) engages the parking lock gear.
