A750E A750F A760E A760F A760H A761E A960E A960F AB60E AB60F Oversized Lockup Relay Valve Kit
Toyota/Lexus vehicles equipped with listed transmissions frequently exhibit TCC and lube/cooler flow problems due to excess wear in the lockup relay valve bore. This bore deterioration allows vital fluid loss, often resulting in TCC apply and release concerns, TCC codes, lube failures, overheating and burned TCC lining. Reconditioning the bore and installing Sonnax oversized lockup relay valve kit 147741-07K restores hydraulic integrity of these circuits and normal TCC/cooler/lube function.
- Hardcoat anodized aluminum valves combat premature wear
- Matched spring helps restore OE performance
Symptoms

Cause
Excess wear in lockup relay bore due to frequent valve stroking prevents proper hydraulic control of TCC, lube and cooler circuits.
