Lockup relay control valve kit

Lockup relay control valve kit • Valve • Sleeve Also fits AF 23/33 and RE5F22A units. • Sleeve is manufactured from highly wear-resistant billet aluminum. • Sleeve has been redesigned to eliminate rotational indexing issues and provide flow 360 around the valve to prevent side loading. • Sleeve design incorporates grooves and cross-slots to maximize valve support while maintaining proper flow. •Valve is made from hard-coat anodized aluminum to prevent wear Symptoms: • Inadequate lubrication • TCC apply & release concerns • TCC codes 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, provides greater valve support, and uses upgraded materials to prevent wear.
