In VW/Audi 01M, 01N and 01P transmissions the TCC boost valve wears the inside diameter of the sleeve due to constant valve oscillation. When wear is significant, oil leaks past the valve, preventing it from properly stroking the converter clutch apply valve into the release position, leading to engine stalls and converter overheat. Sonnax offers TCC boost valve kit 119940-01K that restores hydraulic integrity to the circuit with tight tolerances and proper material.
