A transmission includes a selectable one-way clutch (SOWC) assembly. The SOWC assembly includes a rotatable pocket plate, a rotatable slide plate, and an annular piston having a ramped surface feature. The piston, which can be hydraulically actuated, moves axially toward the pocket plate when applied, and axially away from the pocket plate when released, to thereby select between two torque holding or operating modes of the SOWC assembly. The ramped surface feature of the piston engages an axial knob portion of the slide plate when the piston is applied to select to one operating mode, thus rotating the slide plate in one direction. A return spring moves the piston away from the pocket plate when the other operating mode is selected, and the slide plate is rotated via a spring in another direction. A guide pin maintains a relative position of the piston and the slide plate. |
