What ATF should I use after I replace pan gaskit

one of the very best articles I ever read on torqueflites was in Chrysler Power magazine "Talking Torqueflites"-in which they suggested using the type F fluid-and I've used is since then and like it far better than Dex. If I was to do a pan drop and filter change in a vehicle that had Dex in it, I would drain the torque converter anyway( and not worry too much about the little bit in the lines) and go with type F. Just me...
