Cause:
Bore wear at the spring end of the valve allows the SLT circuit and regulated converter pressure to cross leak. Bore wear at the balance end of the valve reduces converter and lube flow.
Correction:
Sonnax secondary pressure regulator valve kit allows the hydraulic integrity of the bore to be restored after reaming. With the improved materials and valve support, the service life can be extended beyond the OE casting.
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 is designed to correct the pressure outputs from the secondary pressure regulator valve and fix these drivability issues.
