A worn secondary pressure regulator valve in vehicles with Aisin AW TR-60SN and VW/Audi 09D 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 engagement, TCC slip resulting in RPM surge, and poor shift quality. Sonnax secondary pressure regulator valve kit 25741-11K is designed to correct the pressure outputs from the secondary pressure regulator valve and fix these drivability issues.
