If you're working on an older Ford, Lincoln, or Mercury with an AOD or AODE transmission, this extension housing gasket is exactly what you need for a proper seal!
This TEV-012041 part fits a huge range of vehicles from 1980-1995 including Broncos, Crown Vics, Cougars, Continentals, and all those Econoline vans that are still running strong. The compatibility list is massive - we're talking everything from 4.9L straight-six engines up to the big 7.5L V8s. When that extension housing gasket starts leaking, you'll know it from the transmission fluid spots on your driveway and that distinct burning oil smell after driving. Replacement is pretty straightforward if you're comfortable with transmission work - just drop the driveshaft, remove the extension housing, clean both surfaces really well, and install this new gasket with proper torque specs. The quality matches OEM standards, so you don't have to worry about it failing prematurely and causing the same leak issues all over again. We always recommend double-checking your specific vehicle year and engine size before ordering, since Ford used these transmissions across so many different models.
Having a good seal here prevents fluid loss that can lead to transmission damage and expensive repairs down the road. Seriously, if you're seeing transmission fluid leaks from the back of your older Ford product, this gasket is likely the solution you need to get it sealed up properly and keep that transmission running smoothly for years to come.
