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.

• Oversized, hard-coat anodized valve is manufactured to extremely tight tolerances and resists wear
• Salvages previously non-repairable worn valve bodies and avoids expensive valve body replacement castings
