National 224464 Automatic Transmission Extension Housing Seal

Automatic Transmission Extension Housing Seal for Nissan and INFINITI

National 224464 is an automatic transmission extension housing seal built for metric applications that require a precise shaft-to-housing seal. It uses a polyacrylate construction and a counter-clockwise spiral lip design to help maintain sealing performance in the transmission tail housing area.

With dimensions of 1.732 in. inside diameter, 2.452 in. outside diameter, and 0.394 in. width, National 224464 is sized for specific Nissan and INFINITI automatic transmission applications. This seal is a direct-fit service part for many vehicles equipped with Jatco transmissions, including the Nissan Frontier, Nissan TITAN, and INFINITI Q50.

Detailed Description

National 224464 is part of the 220000 series and is engineered as an automatic transmission extension housing seal for select Nissan and INFINITI vehicles. The seal’s metric sizing and spiral lip profile are important for maintaining a consistent seal at the transmission extension housing, where fluid retention and contamination control are critical. This part number is commonly searched for Nissan Frontier transmission seal, Nissan TITAN extension housing seal, and INFINITI Q50 transmission oil seal applications.

This part cross-references Monroe Shocks & Struts (e.g., 17334A, NO-58) for the same application. National 224464 also appears in interchange listings under OE-style references used across Nissan and INFINITI transmission service.

What It Helps Address

• Transmission fluid seepage at the extension housing
• Oil leakage around the output shaft area
• Seal wear from age, heat, and fluid exposure
• Service replacement for damaged or hardened transmission seals
• Maintenance on Jatco-equipped Nissan and INFINITI drivetrains

Installation Notes and Fitment

Verify shaft and housing dimensions before installation. Clean the sealing surface and inspect the extension housing for scoring, corrosion, or debris that could affect seal performance. Proper alignment during installation helps prevent lip damage and premature leakage.
