A park lock assembly for locking and unlocking a park lock gear of a vehicle comprising: a locking lever which is pivotable into and out of engagement with a park lock gear of a vehicle between an unlocked position and a locked, Park, position; a guide plate, which slidably supports a park lock roller assembly having rollers which contact said locking lever and actuate said locking lever to lock and unlock the park lock gear, said guide plate being displaceable in a movement direction between locking and unlocking positions for displacing said park lock roller assembly to pivot said locking lever; an abutment plate member operatively engaged with said guide plate; and said guide plate including an alignment formation for maintaining alignment of said guide plate during said movement thereof, a rack comprising a plurality of gear teeth that is engagable with and drivable by an actuator gear pinion to displace said guide plate in said movement direction; characterized in that: said guide plate and said abutment plate member are formed each as a single-piece component; said abutment plate member includes a spring section for retaining said guide plate in said locking position and said unlocking position; said guide plate includes a detent feature which is engagable with said spring section for retaining of said guide plate in said locking position or said unlocking position; said rack is disposed on a first edge of said guide plate, and said detent feature is disposed on a second edge of said guide plate opposite to said first edge, said teeth extending in said movement direction in which said guide plate moves and said detent feature comprises a plurality of detents which are spaced from each other in said movement direction; and said abutment plate member includes said spring section which extends in cantilevered relation to a base portion thereof, said spring section including a spring feature on an end portion thereof and said spring section being resiliently flexible to bias said spring feature into a respective one of said detents while permitting movement thereof out of said detent to another said detent during said movement of said guide plate. a locking lever which is pivotable into and out of engagement with a park lock gear of a vehicle between an unlocked position and a locked, Park, position;
