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.
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.
Vacuum testing at the port(s) indicated fails to hold the recommended minimum in-Hg, or if wear is visually detected.
