I've used Red Line and Mobil 1 synthetic with success. Any good syn ATF should be fine. Buy 6 quarts and use a little less than that.

Ford says to change the fluid at 50k.Thats when I changed mine.The old fluid looked new,but I changed it anyway.My truck is 4wd ,so I changed the tranfer case fluid also. I'm glad I did because the fluid in the transfer case looked worse than the fluid in the tranny.Use the same fluid in the transfer case (2 quarts).
