Abstract
A selectable one way clutch includes a reverse strut pocket plate having a first plurality of struts or pawls, a reverse notch and forward strut pocket plate having a second plurality of struts or pawls, a selector plate disposed between the plates controlled by a selector plate actuator and a forward notch plate. The reverse notch and forward strut pocket plate includes a plurality of ratchet teeth disposed about its periphery which cooperate with a pin or pushrod of a linear actuator. When the reverse notch plate and forward strut pocket plate is stationary but the one way clutch is still carrying torque, the linear actuator may be actuated to rotate the reverse notch plate and forward strut pocket plate to unlock or release the torque carrying struts which would otherwise remain in their locked torque transmitting positions until all or substantially all torque across the clutch was removed.
