FAG SS2561 Manual Transmission Seal - Rear

Manual Transmission Seal for OE-Style Service

The FAG SS2561 manual transmission seal is built for applications that need dependable sealing at the transmission or transfer case. With a nitrile sealing material, metal spring construction, and auxiliary lip design, it helps maintain a tight seal against contamination while retaining lubricant at the seal interface.

Compatible With select Ford, Jeep, Chevrolet, GMC, Lincoln, Mercury, and Dodge-era driveline applications, this seal is specified for many rear-position uses across manual transmission and transfer case service. The FAG SS2561 is a direct-fit service part for vehicles that require the listed bore and outside diameter dimensions.

Detailed Description

FAG SS2561 is engineered to meet vehicle-specific sealing requirements where the seal must protect internal components from dirt, dust, and moisture while helping prevent grease or fluid loss over time. The seal construction uses a metal case, spring tension, and auxiliary lip to support consistent contact at the sealing surface. This makes it a practical choice for service work on rear-position manual transmission and transfer case locations, including many Jeep Grand Cherokee, Jeep Cherokee, and Ford truck applications.

Fitment coverage includes 2000-2002 Jeep Grand Cherokee, rear; 2002 Jeep Liberty, N/A; 2000-2001 Jeep Cherokee, rear; 1990-1994 Ford F-150, rear; and 1983-1993 Ford Mustang, rear. The FAG SS2561 part number is also used across a wide range of classic Ford, Mercury, Chevrolet, and GMC driveline applications where the listed dimensions match the original seal specification.

What It Helps Solve

• Transmission or transfer case fluid seepage at the seal surface
• Contamination from road debris, dust, and moisture entering the sealed area
• Loss of lubricant that can accelerate wear on internal driveline components
• Service issues caused by a worn or hardened original seal
• Fitment problems when replacing a seal with the wrong diameter or width

Installation Notes and Tips

Verify bore diameter, outside diameter, and seal width before installation. This seal is listed for rear-position applications and many notes reference specific transmissions or transfer cases, including New Process 231, 242, and 249 units, Borg Warner transmissions, and Ford transmission variants. Confirm the vehicle year, make, model, position, and driveline notes against the original part before pressing the seal into place.

Quality Assurance

FAG designs seals using supplier-supported manufacturing standards and vehicle-specific specifications. The SS2561 follows the dimensional and material requirements needed for demanding driveline sealing applications, with construction intended to maintain sealing performance in service.
