Vehicles with Toyota/Lexus U660E and U660F transmissions may exhibit 2nd and 6th Gear shift complaints and burnt B1 clutches. This can be caused by wear at the valve and/or boost valve and sleeve which leads to improper valve function. Reconditioning the bore and installing the Sonnax oversized B1 apply control valve kit 47740-57K will restore valve function.

Sleeve manufactured from highly wear-resistant aluminum
Hardcoat anodized aluminum valves combat premature wear
Annular grooves help center valve to reduce side-load wear
Valve designed to reuse OE spring
