This Explorer came in with a transmission leak. When I inspected it, I found that the transmission tailshaft seal had slipped out of the back of the trans extension housing. This video shows what I did to replace the seal & keep the problem from happening again.

  • Hey please respond to my comment, I have a 1984 lincoln towncar and it has a leaky transmission,would this be the same as a rear main seal? And the same process to replace it basically?

  • @The18Jake The rear main is in the back of the engine. It usually requires transmission removal. That would be an engine oil leak, not ATF.

  • @roadragecustoms Well I was hoping I was right...lol. Does the tranny need to be completely disengaged from the engine? Or just scooted back with the drive-shaft removed? Do you think that could work? Any tips or tricks on replacing one?

  • @The18Jake Yes, complete removal is best.

  • you make it look so easy. iv been trying to do the seals on my 89 cavalier for almost a month now. i just cant get them in straight. how would i do it?

  • @rsteveball I have an output shaft seal installer kit from Snap-On that helps on most front wheel drive vehicles.
