- Inadequate lubrication
- TCC apply & release concerns
- TCC codes
A sticking lockup relay control sleeve prevents TCC apply or release. Sleeve wear reduces converter pressure, overheating the fluid, and results in bushing and solenoid failure.
The tightly toleranced, drop-in replacement Sonnax valve and sleeve assembly restores proper hydraulic clearances, and uses upgraded materials to prevent wear.
