Common complaints associated with Ford 5R55N, 5R55W and 5R55S transmissions are converter slip and code P0741. These complaints often occur at relatively low mileage. Wear at the TCC modulator valve bore reduces apply pressure to the converter clutch and line pressure. Excessive leakage anywhere on this valve body increases the foaming of the oil. This foaming increases the venting action from the breather. The Sonnax TCC modulator valve kit 56947J-15K includes a hardcoat anodized valve that is supported through its entire stroke. The kit also includes two springs calibrated for either 5R55N or 5R55W and 5R55S valve bodies. Valve and sleeve assembly provides better support and wear resistance than the OE design Hardcoat anodized aluminum valve combats premature wear Assembly and tool kit work in both 5R55N and 5R55W and 5R55S units
