The leakage lowers the apply pressure, which causes the torque converter clutch to slip. Sonnax TCC regulated apply valve kit 84754-34K addresses TCC slip, code 741 and occasional ratio codes. Hardcoat anodized valve combats premature wear Valve has annular grooves to prevent side loading Wear-resistant sleeve is much more durable than the valve body casting and provides additional valve support Note It is recommended to check separator plate orifices for contamination. Additionally, the TCC apply valve bore should be examined for wear with any TCC related concerns
