Abstract
A shift by wire parking system includes a park gear including a gear body and a plurality of teeth. The teeth are circumferentially spaced from one another. The park gear defines a plurality of void spaces between each pair of the plurality of teeth. The shift by wire parking system includes a circumferential body sized to fit inside each of the plurality of void spaces to lock a position of the park gear. The circumferential body is movable towards and away from the park gear between an engaged position and a disengaged position. In the disengaged position, the circumferential body is disposed outside each of the plurality of void spaces, thereby allowing the park gear to rotate. In the engaged position, the circumferential body is disposed inside one of the void spaces to lock the position of the park gear.
