NEW! Toyota/Lexus Oversized Primary Pressure Regulator & Reverse Boost Valve Kit

Toyota/Lexus U660E, U660F and U760E units often exhibit a variety of symptoms such as poor line rise, clutch/brake slippage, high/low line pressure, and erratic shifts. Featuring hardcoat anodized aluminum valves to combat premature wear, the new, patent pending Sonnax oversized primary pressure regulator & reverse boost valve kit 47740-02K will conquer these problems and restore full hydraulic control.

  • Annular grooves on the valve help center it in the bore reducing future side-load wear
  • Wear-resistant aluminum boost sleeve
  • Dual-ratio reverse boost valve assembly can be used with either OE ratio
