Severe wear of the TC pressure regulator valve bore in VW/Audi 09A and Jatco JF506E units results in leakage of converter release/lube/cooler oil pressure that compromises unit durability, resulting in damaged TCC linings, overheated converters and lube failures. Reconditioning the bore and installing Sonnax TC pressure regulator valve kit 122892-10K restores the hydraulic integrity of the circuit allowing you to salvage these valve bodies.
- Salvage valve bodies with worn TC pressure regulator valve bores
