I am getting a re-manufactured transmission. I was told that everything but the shell is brand new. I believe it also comes with a new cooler. Ford backs it with a three year, unlimited mileage warranty. As for the fluid type, I will double check the paperwork. I do remember having a conversation with the service writer about using the correct fluid. I also had to convince her that the truck had a Torqueshift. She swore up and down that Ford never put the Torqueshift in a gas Superduty. She even called a mechanic over to prove her point. He climbed under the truck and announced that he didn't know what tranny he was looking at. I probably should have left at that point. I have never been back.
