Sonnax 5R55N/W/S Pump Flow Control Valve Kit 56200-03K
In Ford 5R55N, 5R55S and 5R55W units, the OE flow control valve is designed to increase pump efficiency by rerouting excess line pressure back to the suction side of the pump. It is common for the plunger valve to become stuck open, or for the canister to wear. This decreases line pressures and results in delayed engagements. Sonnax pump flow control valve kit 56200-03K eliminates the sticking and wear problems with redesigned and precision-machined parts.
Harder canister material resists wear and has improved valve support to prevent stickingPlunger valve is made from case-hardened steel and has annular grooves to prevent side loadingLarger O-ring eliminates pressure loss at the pump faceCanister restores the regulated line orifice to improve valve and hydraulic stabilityDrop-in replacement for easy installation
