A worn secondary pressure regulator valve in vehicles with listed Aisin AW, VW/Audi, and Mini transmissions can cause several problems. Overheating the fluid, bushings, and torque converter can all be caused by a worn secondary pressure regulator valve. Drivability issues include harsh Reverse, TCC slip, and poor shift quality. Sonnax secondary pressure regulator valve kit 15741-11K is designed to correct the pressure outputs from the secondary pressure regulator valve and fix these drivability issues.

• Hardcoat anodized aluminum valve combats premature wear
• Annular grooves have been added to the valve for better centering in the bore
• The highly wear-resistant Sonnax sleeves provide over 80% more support than the OE casting
• A new spring is included to allow proper calibration
