Wear can occur in Gen. 1 and Gen. 2 Ford 6F35 clutch control valve bores. This wear allows critical clutch apply pressure and oil loss which can cause shifting issues and a burnt clutch. Reconditioning the bore and installing Sonnax oversized low reverse/overdrive (4-5-6) clutch regulator valve kit 144740-43K restores correct pressure regulation.

New spring matches OE calibration
Hardcoat anodized aluminum valve combats premature wear
Annular grooves help center valve in bore to reduce future side-load wear
O-Ringed end plug provides positive sealing
