Abstract
A system for shifting a transmission range includes a selector producing a signal representing a selected range, and the system has a primary state wherein a source of electric power shifts the transmission to the selected range in response to the signal, and a secondary state wherein a source of mechanical energy shifts the transmission to a Park range when the primary state is unable to shift the range.
