Detailed Description

National 3622 is an oil seal engineered for the transmission output shaft area where accurate sealing is critical. The 1.654-inch inside diameter, 2.524-inch outside diameter, and 0.394-inch width support a precise fit in the housing bore, while the flanged outside diameter measures 2.805 inches. This seal is specified for a broad range of Ford Taurus, Ford Escort, Ford Windstar, Mercury Sable, Mercury Cougar, Lincoln Continental, Mazda 626, Mazda Tribute, and Ford Freestar applications, including vehicles equipped with Ford CD4E, AX4S, AXOD-E, AXOD, ATX, MTX-II, MTX-III, MTX-IV, and 4F50N transmissions.

National has supplied sealing solutions for more than 75 years, and this part reflects that focus on transmission sealing accuracy and material selection. National 3622 is a direct-fit style replacement for service work on Ford Taurus, Mercury Sable, and related front-wheel-drive transmission platforms where output shaft sealing is required.

What This Seal Helps Address

• Transmission fluid leaking from the output shaft area
• Fluid seepage around the transmission housing bore
• Seal wear from age, heat, and normal drivetrain operation
• Loss of sealing integrity on Ford CD4E, AX4S, AXOD-E, and related transmissions
• Service replacement needs on Ford Taurus, Mercury Sable, and Mazda 626 applications
