Product Description
01M 01N 01P Oversized TCC Boost Valve Kit
No tooling required
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.
- Hardcoat anodized aluminum valve combats premature wear
- Sleeve made from from highly wear-resistant aluminum
- TCC spring included in kit replaces broken OE part
- Drop-in Zip Valve™ parts install quickly and easily
Symptoms
- Engine stall on stop
- Engine stall on N-D engagement
- Overheated converter
Cause
Wear between the TCC boost valve and sleeve will prevent proper stroking of the converter clutch apply valve to the release position.
Correction
