Abstract: The present disclosure provides a bidirectional controllable overrunning clutch for a powertrain of a motor vehicle, with the powertrain including a gear having ratchet teeth. The clutch includes a pawl movable to a disengaged position, a locked position, and a transition state where the pawl permits the gear to rotate in the forward direction and where rotation of the gear in the reverse direction moves the pawl to the locked position. The clutch further includes a spring for moving the pawl to the disengaged position. The clutch further includes an actuator configured to hold the pawl in the transition state when the gear rotates in the forward direction and the locked position when the gear changes rotation from the forward direction to the reverse direction.
