A side cover for use in a transmission includes an inner surface and a wall. The wall extends along the outer periphery of the side cover. The inner surface and the wall cooperate to define a cavity. A fluid control valve is disposed in the bottom of the side cover within the cavity. The fluid control valve controls the height of hydraulic fluid in the side cover by varying flow to the sump. The cavity includes a fluid storage portion in communication with the valve. The fluid storage portion has a volume that is greater at a bottom of the side cover than at a top of the side cover. The fluid storage portion controls the pressure of the hydraulic fluid at the valve.
