Common problems in vehicles equipped with ZF6HP21/28/34 (Generation 2) transmissions include an overheating torque converter, low TCC release pressure, torque converter clutch slip and firm shifts. One cause of these problems is a worn out bypass clutch control valve, resulting in slow apply and release of the TC clutch. Installing the Sonnax oversized bypass clutch control valve kit 95740-73K restores the factory torque converter clutch apply and release rates.

• Kit fits either M-shift or E-shift valve bodies
• Additional valve spool length at the balance port for better sealing
• Valve is hardcoat anodized to reduce wear
• Annular grooves for better centering the valve in the bore
