A frictional engagement assembly for an automotive device, including: at least one frictionally engageable plate; a first piston plate displaceable in a first axial direction to urge the at least one frictionally engageable plate into frictional contact; a first resilient element engaged with the first piston plate and urging the first piston plate in a second axial direction substantially opposite the first axial direction; a check valve controlling fluid flow to displace the first piston plate; and an accumulator. As fluid from a chamber, at least partially formed by the first piston plate, discharges through the check valve, the accumulator controls fluid volume in the chamber to maintain a distal portion of the first piston plate, urging the at least one frictionally engageable plate into frictional contact, in a furthest position in the first axial direction.
