Automatic Transmission Extension Housing Gasket

ATP Parts FG-154 is an automatic transmission extension housing gasket made for exact-fit replacement service. It is built for Ford, Mazda, and Mercury applications where a precise seal at the transmission extension housing is needed to help maintain proper fluid control.

Key Features

  • Exact-fit replacement gasket for automatic transmission extension housing service
  • Paraphrases ATP’s sealing focus: built to match the original application without compromise
  • Fits a wide range of Ford Ranger, Ford Explorer, and Mazda B-Series applications
  • Also listed for Ford Mustang, Ford Bronco II, Ford Aerostar, and related Mercury models
  • Part number FG-154 for catalog and cross-reference lookup

Detailed Description

ATP Parts FG-154 is an automatic transmission extension housing gasket for vehicles including the Ford Ranger, Ford Explorer, Mazda B2300, Mazda B3000, Mazda B4000, and Mercury Mountaineer. It is also listed for additional Ford and Mercury applications such as the Mustang, Bronco II, Thunderbird, Capri, Marquis, Zephyr, Cougar, Pinto, and Bobcat. This part cross-references Four Seasons 45006 for the same application.

Use FG-154 when servicing the transmission tail housing area and you need a replacement gasket that matches the original fitment profile. The broad vehicle coverage makes it a practical choice for long-running Ford and Mazda platforms, including 1974-2006 applications.

What It Is Used For

  • Replacing a leaking extension housing gasket
  • Restoring a proper seal at the transmission tail housing
  • Addressing fluid seepage around the rear of the automatic transmission
  • Supporting transmission service on Ford Ranger and Ford Explorer platforms
  • Servicing compatible Mazda B-Series and Mercury applications

Installation Notes and Tips

Clean both mating surfaces thoroughly before installation and inspect the housing for damage, warpage, or old sealant residue. Verify transmission application details carefully, especially for the 1974 Ford Pinto listing, which notes C3-only fitment. Confirm the vehicle year, make, model, and transmission configuration before ordering FG-154.

Quality Assurance

ATP Transmission Seals and Gaskets are positioned as exact-fit replacement parts for transmission sealing service. FG-154 is cataloged for direct application matching across the listed Ford, Mazda, and Mercury vehicles.
