Sonnax 119940-01K TCC Boost Valve Kit for VW/Audi 01M 01N 01P Transmissions

The Sonnax TCC boost valve kit 119940-01K restores hydraulic integrity to the circuit with tight tolerances and proper material for VW/Audi automatic transmissions. This drop-in Zip Valve repair kit is designed to address a common failure in 01M, 01N, 01P, and 099 transmission models.

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.

Kit Includes:

• Hardcoat anodized aluminum valve that combats premature wear
• Sleeve made from highly wear-resistant aluminum
• Replacement TCC spring, as the original is often broken

This valve body repair kit installs quickly and easily, eliminating the need for costly valve body replacement. The precision-engineered components prevent hydraulic leakage and restore proper torque converter clutch control, resolving issues related to engine stalling and transmission overheating.
