National 710486 Automatic Transmission Extension Housing Seal
Automatic Transmission Extension Housing Seal
National 710486 is an automatic transmission extension housing seal built for metric applications with a 39.000 mm shaft diameter and 72.240 mm outside diameter. It uses a fluoro-elastomer sealing material and a counter-clockwise spiral lip design to support a secure seal at the transmission extension housing.
Compatible With BMW, Chrysler, Dodge, Ford, Jaguar, Jeep, Maserati, Mercury, Lincoln, and Ram applications listed below, this seal is specified for a wide range of rear transmission output and extension housing service needs. The National 710486 part number is also referenced in OE-style replacement searches for BMW X5, Jeep Grand Cherokee, and Ram 1500 transmission repair.
Key Features
- National 710486 automatic transmission extension housing seal
- Metric dimensions: 39.000 mm inside diameter, 72.240 mm outside diameter, 8.000 mm width
- Fluoro-elastomer construction for sealing performance in transmission service
- Counter-clockwise spiral lip design
- Housing bore: 72.000 mm
- Part description: oil seal
- Series: 710400
Detailed Description
National 710486 is engineered as an extension housing oil seal for automatic transmissions that require a metric seal with a 39 mm shaft and 72 mm housing bore. The fluoro-elastomer material is selected for sealing durability in transmission environments, while the spiral lip design helps maintain contact at the rotating shaft interface. This part number is used across many late-model and earlier vehicles, including BMW X3, BMW X5, Jeep Grand Cherokee, Dodge Charger, and Ram 1500 applications.
This part cross-references Carlson 15324 for the same application.
What It Helps Address
- Transmission fluid seepage at the extension housing
- Leakage around the output shaft seal area
- Seal wear from age, heat, and fluid exposure
- Service replacement during transmission repair or rebuild
- Fitment-specific sealing needs on BMW, Jeep, Ram, Ford, and Chrysler vehicles
Installation Notes and Tips
Verify shaft diameter, housing bore, and seal width before installation. Clean the extension housing and shaft sealing surface thoroughly, and inspect for grooves, corrosion, or damage that could affect sealing. Confirm the transmission code and application notes, especially on BMW models with ZF 8HP-45X, ZF 8HP-70X, ZF 6HP-19X, ZF 6HP-26X, or ZF 6HP-28X transmissions. Fitment examples include Fits 2016-2019 BMW X5, N/A; Fits 2014-2019 Jeep Grand Cherokee, N/A; and Fits 2013-2019 Ram 1500, N/A.
Quality Assurance
National has supplied sealing solutions for more than 75 years and continues to develop transmission sealing components for modern vehicle platforms. Part number 710486 is built to the listed dimensions and material specification for service replacement use.
