Vehicles equipped with Toyota/Lexus U660E/F or U760E/F transmissions may exhibit problems related to the B2 brake clutch. These include a delayed or harsh reverse engagement or a double bump when the B3 brake clutch applies before the B2 brake clutch.
These concerns can be traced to a worn and/or sticking B2 control valve and plug valve. Sonnax offers oversized B2 control valve kit 47740-35K, which renews valve function to restore normal Reverse operation.
