yes, back in late 2000 or early 2001 Ford changed the spec from ATF to the XT-M5-QS which is what is commonly referred to as Ford Honey (due to its color). this is really the best choice but its also quite expensive at about 20$+ a quart usually.According to my chart @ work .. mtx75 1995-2011, XT-M5-QS (Full synthetic MTX fluid)
What kind (brand) of fluid should i be looking for? Also what thickness?ATF works just fine. I have nothing but ATF in every MTX75 i have had and have almost 600K miles (249K, 225K, 125K) combined on them without a single issue. the supposed issue according to Terry Haines is that ATF swells the bushings in the shift forks, but the bushings are metal (or on the later 1/2 fork its got ball bearings in it) and its just not possible for a fluid to swell a metal.
