hey guys I finally found a new trans and I am installing it in my car tomorrow. The only confusion I have had is that I cant find a straight answer of type of fluid it takes. Mercon, I,II,IV? I just want to put the ford recommended fluid back in so I dont have any problems.

That's not the Ford recommended fluid. Tremec in the past has recommened against it in the T-5 due to potential incompatiblity with the synchro blocker ring linings. Of course, many people run the fluid with no issue.
