In Toyota/Lexus U660E and U660F units, 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. The result is line pressure leakage and excess SL, SLT, and SLU solenoid pressure which floods the solenoids and creates shift quality concerns, solenoid codes and deviation of proper control pressures available to various valves. Sonnax oversized solenoid modulator valve kit 47740-24K allows you to recondition the bore and install improved components to restore normal solenoid supply pressures.

Hardcoat anodized aluminum valve combats premature wear
Annular groove aids in centering the valve in the bore which helps prevent future wear and side-loading

Note

Tool kit F-47740-TL24 can also be used to install oversized solenoid modulator valve kit 47740-25K.
