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
