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 and sleeve kit 122892-10K restores the hydraulic integrity of the circuit allowing you to salvage these valve bodies.

• Salvage valve bodies with worn TC PR valve bores
• Restores normal converter charge and cooler flow
• Corrects harsh or no TCC apply, TCC slipping and burn-up
