Toyota/Lexus vehicles equipped with listed transmissions often exhibit TCC apply and release concerns, TCC or ratio codes, RPM surging, harsh downshifts and overheated fluid. These problems can be caused by deterioration of the lockup control sleeve due to constant valve oscillation within the sleeve. Installing Sonnax lockup control plunger valve kit 157740-37K prevents crucial pressure escape, correcting these issues and restoring normal operation.
