Answer me this then. If the MTX-75 at one time was spec'd to run ATF. Then why run MTL? States on the back of an MTL bottle..."For transmissions recommending an ATF, Red Line D4 ATF should be used." So why are people using MTL
versus Redline D4 ATF?





Perhaps because Ford changed the spec from ATF to gear oil? That sounds to me like either one could be correct, but the gear oil would be preferred. After all, ATF was the spec for five model years.

About black residue when using Mercon. Has anyone paid attention to what NEW Mercon looks like? Pour a little in a manner that you can see light through the pour, and notice the BLACK that is in it. It gives Mercon a sort of a smokey color. That is part of the additive package and part of what makes Mercon (and Dexron) unique from other trans fluids. ATF+3 doesn't have that. It is optically clearer. Could part of the black residue you see left behind be that black additive?
