Abstract
A transmission is shifted into a reverse state. The transmission includes a clutch. The clutch includes a pocket plate, a notch plate, a first strut housed within a pocket of the pocket plate, and a second strut housed within another pocket. A command is received to shift the transmission to reverse. It is then determined whether the at least one second strut has retracted into the pocket plate. If it remains extended, the first actuator is activated. A first rotational torque is applied to the notch plate in a direction allowing the notch plate to abut the first strut. By doing so, the second strut is released from abutting engagement with the notch plate. A second rotational torque is applied to the notch plate opposite the first rotational torque to rotate the notch plate out of engagement with the first strut, resulting in the transmission entering the reverse state.
