Early 99 F250 4x4 auto 7.3
Engine Oil: Any CJ-4 motor oil
Tranny Fluid: Mercon or according to FoMoCo Mercon V (it is been debated what will happen to your trans since when the 4R100 first came out Ford didn't spec Mercon V but now it says its ok to run it) Do a search for Mercon V, lots and lots of threads on it.
Transfer Case Fluid: Dex/Merc ATF
Rear End Fluid: Synthetic 75w-140 for SRW, 75w-90 for DRW
Front End Fluid: 75w-90, doesn't spec synthetic but it is not a bad idea
Power Steering Fluid: Mercon ATF
Brake Fluid: DOT 3
Washer Fluid: (lol, no, not really)
Thanks In advance,
