Tooling Required
U341E U341F Oversized Lockup Relay Valve Kit
Toyota/Lexus U341E and U341F lockup relay valve trains route converter feed fluid to the release side of the converter clutch and apply fluid into the cooler circuit. Converter feed pressure at the lockup relay control plunger valve helps in positioning of the outboard lockup relay valve. Wear or sticking at either the relay or plunger valve bores can result in converter apply and release concerns, inadequate lubrication, overheated fluid and converter codes. Installing Sonnax oversized lockup relay valve kit 33740-11K restores critical clearances for renewed TCC control and operation.
- Hardcoat anodized aluminum valve combats premature wear
- Annular grooves provide centering
Symptoms

Cause
Excess wear in the lockup relay and plunger valve bores allows pressure loss and causes valve sticking that leads to TCC and lubrication failures.
Correction
