Sonnax highlights oversized overdrive servo regulator valve kit

Sonnax highlights its oversized servo regulator valve kit (part no. 76948-59K) for Ford 4R70E/W and 4R75E/W transmissions. Sonnax says the kit can help users maintain critical tolerances that re-establish the hydraulic integrity of the overdrive servo circuit.

This kit features a hardcoat anodized aluminum valve that the company says combats premature wear and maintains proper clearance at all temperatures. It also includes a closely toleranced boost sleeve that Sonnax says improves sealing.
