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.

A parking actuator assembly for an automatic transmission includes a park pawl that is rotatable between an in-park position and an out-of-park position. An actuator assembly is configured to be moved between a park-actuated position and a park-disengaged position, the actuator assembly being configured to rotate the park pawl into the in-park position when the actuator is moved into the park-actuated position. An actuator rod is slidably coupled to the actuator assembly. In some forms, the actuator assembly remains in contact with the park pawl from the park-actuated position to the park-disengaged position. In some forms, at least one latching solenoid is included, and the latching solenoid(s) as well as a park actuator motor may be disposed within a main transmission system. A verification sensor may be included to determine the position.
