Abstract
A vehicle includes an automatic transmission having an engine, an input member, a stationary center support, and a selectable one-way clutch (SOWC) positioned within the stationary center support. A SOWC selection mechanism is formed integrally with the center support, and rotates a slide plate during a predetermined transmission operating mode. A piston in a first bore of the selection mechanism rotates the slide plate in a first rotational direction to engage the SOWC, and a return spring in a second bore of the selection mechanism rotates the SOWC in a second direction to disengage the SOWC. The slide plate has a tab portion, and the piston and the return spring alternately apply a respective first and second force to opposite sides of the tab portion to rotate the slide plate, either directly or via an adapter ring.
