This Transmission Valve Body Gasket Set is a high-quality replacement part designed specifically for repairing Ford and Mazda vehicles equipped with 4R44E, 4R55E, or 5R55E automatic transmissions from 1995 to 2012.

The set fits a range of popular models, including the Ford Ranger, Explorer, Mountaineer, and Mazda B-Series (e.g., B2300, B2500, B3000, B4000). This kit is an essential component for transmission valve body servicing, maintenance, or rebuilds, effectively helping to restore transmission seal integrity, prevent pressure loss, and ensure smooth, reliable shifting.
