The only trans to watch out for is the 6R75E.

 

Well it looks like i wont be staying with all of you in the 2007+ forum. Just wanted to give an update. We purchased a very babied 2005 lincoln navigator ultimate. Folders of maintence records, garage kept , top to bottom pro detail every six months...its beautiful. Seller is still calling to check on his truck. One might think he misses it. Anyhow, thanks for all the advice!
