TC Pressure Regulator Valve & Sleeve Kit
Severe wear of the TC pressure regulator valve bore results in leakage of converter release/lube/cooler oil pressure that compromises unit durability, resulting in damaged TCC linings, overheated converters and lube failures. The Sonnax kit 122892-10K salvages these valve bodies.
- Salvages 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.
