A vehicle includes a front-wheel drive (FWD) transmission having a case, a selectable one-way clutch (SOWC) indexed to the case, pressurized fluid, and a valve body assembly (VBA). The VBA has a piston in communication with the fluid, a return spring, and an actuator plate in continuous contact with or connected to each of the piston and a shift lever of the SOWC.
