Common problems in vehicles equipped with ZF6HP19/26/32 (Gen. 1) and Ford 6R60, 6R80, 6R100 transmissions include torque converter clutch slip, firm shifts and an overheating torque converter. One cause of these problems is a worn bypass clutch control valve resulting in slow apply and release of the torque converter clutch. Installing the Sonnax oversized bypass clutch control valve kit 95740-13K restores factory torque converter clutch apply and release rates. This will resolve the converter slip, harsh shift and overheating problems.

• Hardcoat anodized aluminum valve combats premature wear
• Valve is tighter fit to the bore than OE for better sealing
• Valve has annular grooves for better centering in the bore
