I posted about this somewhere, but the botom line is it has to have the SAE spec on the bottle, and if you look real close, none of the dual usage fluids do, they just say compatible with MERCON, even though the fine print will list a spec number that isn't. The only two things I would put in one are Motorcraft MERCON, or Mobil 1 Synthetic, but any name brand is prolly fine, fluid is pretty much a commodity, as long as the additives are compatible, but Highly Friction Modified fluid (Mercon V and such) are not, the HFM chemicals break down the soft parts over time. That's the reason Ford did not switch the 4R100 to HFM fluid in the first place, a good argument can be made that it's better fluid, it stops converter shudder most of the time, but it don't work in a 4R100. I can't think of any of the designer fluids (Royal Purple, REdline etc...) that are remotely worth the money, excpet to say that a synthetic fluid will hold up in high temps better as a general rule. I use Mobil 1 because it's provided to me for nothing, I wouldn't pay for it living here, maybe if I was in AZ or FL or someplace hot.
