Yes
Ford ATF will not have Dextron in it, for some reason they are out of step with everyone else, though Ford auto boxs are some of the best in existance.
Basically you are using ATF as a hydraulic oil, not for it's friction enhancing properties like an auto box does, so if it's red and oily it will do.
I'd recomend a DII or DIII though, but basically if you buy what your gearboc needs then you avoid any embarasing mistakes with that.
