NO!!!!! I almost made this same mistake myself a while back. I had some left over from my '68El camino. The mtx-75 used in these cars REQUIRES an
ATF type fluid. A lot of us [myself included] drained the factory stuff out for a "synthetic ATF/friction modifier" blend. I don't recall how many ounces of the modifier to add. Try doing a search for, "the cocktail", in the general, or problems forums, it should be there someplace.
