Transmission Parts 丰田和雷克萨斯 U241EU240EU140FU140E Valve Body Valve / Sleeve

Symptoms:

Slips & flares
Harsh upshifts
Bind-up
Harsh Reverse
TCC cycling
TCC slip
Excess Reverse pressure & distorted housings
Low cooler flow
Overheating

Cause:

Excessive solenoid pressure is caused by line pressure side-loading the steel solenoid modulator valve and the continuous oscillation of the valve, which wears the cast aluminum bore.

Correction:

Sonnax solenoid modulator valve and high-grade aluminum sleeve allows the bore to be refurbished, and prevents side-loading of the valve and future wear.

In Toyota/Lexus U140E, U140F, U240E and U241E 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 causing shift and TCC concerns. Sonnax solenoid modulator valve kit 57917E-13K restores normal solenoid supply pressures.

High-grade aluminum sleeve resists wear and provides porting to prevent valve side-loading
Hardcoat anodized aluminum valve combats premature wear, incorporates annular grooves to prevent side-loading
Replacement spring resets regulated pressure to OE specification
