Toyota 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 shores up the hydraulic integrity of these circuits, restoring normal TCC/cooler/lube function.
