Toyota/Lexus U660E, U660F, U760E and U760F transmissions may exhibit 3-4 shift flares, slipping in 4-5-6, and burnt C2 clutches due to wear in the C2 apply control bore. Sonnax oversized C2 apply control valve kit 47740-63K restores the necessary hydraulic clearances required for proper valve function.

Hardcoat anodized aluminum valves combat premature wear
Future side-load wear is decreased by addition of annular grooves, which help center valves in bore
