Abstract
A transmission includes a housing, a park gear, and a vehicle park shifting system configured to selectively engage the park gear to shift the transmission into and out of a park position. The vehicle park shifting system includes a linkage operably associated with the park gear, an actuator assembly operably coupled to the linkage and configured to be actuated to selectively move the linkage into and out of engagement with the park gear, and a lost motion manual shifter assembly operably coupled to the linkage and including a shift shaft disposed at least partially within the housing. The shift shaft is configured to couple to a manual park release system utilized to manually shift the transmission into and out of park without utilizing the actuator assembly. Actuation of the actuator assembly does not impart rotational movement to the shift shaft.
