Toyota A750E/F transmissions may exhibit poor shift quality due to wear in the clutch control bore. The clutch control valve controls clutch apply and release rates. The wear is typically visible upon inspection of the valve and bore. The Sonnax oversized clutch control valve kit 147741-22K allows the bore to be refurbished and the hydraulic integrity of the circuit to be restored.
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.
Either a wet air test (WAT) or a vacuum test in the locations shown result in leakage, or wear is evident at the valve and bore.
