In Toyota/Lexus U151E, U151F and U250E 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 27741-13K restores normal solenoid supply pressures.

• High-grade aluminum sleeve resists wear and provides porting to prevent valve side-loading
• Hardcoat anodized aluminum valve incorporates annular grooves to combat premature wear and side-loading
• Replacement spring resets regulated pressure to OE specification
• Tool kit can also be used for 56947J-23K, 56947J-29K, 56947J-56K and 56947J-59K
