Cause:
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.
Correction:
The tightly toleranced, drop-in replacement Sonnax valve and sleeve assembly restores proper hydraulic clearances, and uses upgraded materials to prevent wear.
Sleeve is manufactured from highly wear-resistant billet aluminum.
Valve is made from hard-coat anodized aluminum to prevent wear
