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 TCC boost valve kit 119940-01K restores hydraulic integrity to the circuit with tight tolerances and proper material.
Sonnax valve body layouts provide a detailed overview of individual units making it quick and easy to determine what’s available for the specific valve body you’re working on. See all Sonnax valve body layouts.
