I was doing a little reading regarding the attributes of paraffinic vs. naphthenic oils with respect to grease making and got to wondering, why not try soaping up an ATF? I think I'll initially try a cheapo Wally World brand, but which formulation? I believe there are some formulations that are friction modified and some that are not. Anyway, what does that mean? Do the manufacturers add components to increase friction or decrease it? I assume the manufacturers are playing with the shifting characteristics when they use "friction modifiers".
