In Toyota/Lexus U760E/F transmissions, the B1 brake clutch is applied in 2nd and 6th Gears. The B1 apply control valve redirects line pressure to the brake clutch. Wear at the valve and/or boost valve and sleeve can cause improper valve function, and in extreme cases, reduction in line pressure. Reconditioning the bore and installing Sonnax oversized B1 apply control valve kit 47740-44K will control line pressure losses and 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
Properly calibrated spring to match OE pressures
