Abstract
A torque based park lock assembly for motor vehicles, especially passenger cars and trucks equipped with automatic transmissions, includes a lobed wheel secured to a transmission output shaft and a rotation restricting flexible lever which may be selectively moved into engagement with the lobed wheel by a cam. A bidirectional motor rotates the cam. A return spring translates the lever away from the lobed wheel when the cam is rotated into a disengaged (non-Park) position.
