In Toyota/Lexus U151E, U151F and U250E transmissions, the steel OE solenoid modulator valve is prone to side-loading in the bore. This side-loading action, combined with repeated oscillation of the valve, prematurely wears the cast aluminum bore causing shift and TCC concerns. Sonnax solenoid modulator valve kit 27741-13K restores normal solenoid supply pressures.
