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.

Hardcoat anodized aluminum valves combat premature wear
Future side-load wear is decreased by addition of annular grooves, which help center valves in bore
Proper reverse operation depends on a correctly functioning B2 accumulator; if problems are found with B2 accumulator piston or bore, Sonnax offers B2 accumulator piston kit 47740-11K
