Listed Toyota transmissions have lockup relay valves that route converter feed fluid pressure to the release side of the converter clutch and apply fluid into the cooler fluid circuit. Converter feed pressure at the lockup relay control plunger valve helps in proper positioning of the inboard lockup relay valve. Wear at these valves can result in converter apply and release concerns, inadequate lubrication, overheated fluid, bushing and solenoid failure, as well as converter codes. Sonnax oversized lockup relay valve kit 97741-20K restores the proper hydraulic clearance to re-establish OE function and performance.
- Hardcoat anodized aluminum valve combats premature wear
- Sleeve redesign eliminates rotational indexing issues and provides 360° flow around the valve which prevents side loading
- Sleeve redesign incorporates grooves and cross-slots to maximize valve support while maintaining proper flow
