Toyota/Lexus U660E/F and U760E/F transmissions may exhibit delayed/slipping Reverse or no Reverse operation at all due to wear in the B2 apply control bore. The B2 apply control valve train regulates reverse clutch apply and release. If reverse slippage is not corrected in time, burnt B2 clutches can result. Sonnax oversized B2 apply control valve kit 47740-27K restores the necessary hydraulic clearances required for proper valve function, eliminating reverse apply issues.
Spring included in this kit is used in all U660E/F and U760E applications regardless of OE spring color.
Sonnax valve body layouts provide a detailed overview of individual units making it quick and easy to determine what’s available for the specific valve body you’re working on. See all Sonnax valve body layouts.
