U660E U660F Oversized Solenoid Modulator Valve Kit
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
Symptoms
- Shift concerns
- Solenoid performance codes
- TCC apply & release concerns
Cause
Side-loading of the steel OE solenoid modulator valve causes bore wear, resulting in excess solenoid supply pressure.
Correction
Restore normal operation by reconditioning the bore and installing the Sonnax oversized solenoid modulator valve kit.
