Beschreibung
Zusammenfassung:	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.
