Cause:
Bore wear at the D1 or E clutch control valve allows pressure loss that causes driveability concerns.
Correction:
Renew clutch action and restore normal shift operation by reconditioning the bore and installing Sonnax oversized D1/E control valve kit.
Flare upshifts or downshift bind-ups are common problems in vehicles equipped with ZF6HP19/26/32 (Gen. 1) and Ford 6R60, 6R80 transmissions. These problems can be accompanied by a coastdown neutral condition or pressure control out of range codes. The clutch control valve controls clutch apply and release timing, and problems occur when the clutch control valve or bore wears. To fix these issues, Sonnax offers the oversized clutch D1/E control valve kit. Installing this kit will restore shift timing and vehicle drivability.
Can be used in either clutch D1 or clutch E location
Tighter fit to the bore than OE for better sealing
