ABSTRACT:
An electronic transmission range selection (ETRS) system for shifting a transmission range of a transmission includes an electro-mechanical park inhibit assembly that operates to disallow the ETRS system from shifting from an Out-of-Park mode to a Park mode under certain circumstances. The park inhibit assembly includes a follower having a recess defined thereon and slidably disposed within a follower bore. In one embodiment a selectively energizable solenoid assembly is mounted substantially perpendicular to the follower and operates to bias a ball into the recess when energized thereby locking the ETRS system in the Out-of-Park mode. In another embodiment the park inhibit assembly includes a selectively energizable motor assembly mounted substantially perpendicular to the follower. The motor assembly operates to enforce the Park and Out-of-Park mode of the ETRS system.
