Toyota/Lexus vehicles equipped with AB60E and AB60F transmissions often display various TCC malfunctions and problems related to reduced cooler flow. These issues can be caused by excess wear in the lockup control valve bore, which allows crucial pressure to escape the circuit. Reconditioning the bore and installing Sonnax oversized lockup control valve kit 157740-16K eliminates wear and restores normal TCC and cooler function for trouble-free operation.

  • Annular grooves help center valves in bore and sleeve to reduce future side-load wear
