I think if it is Mercon rated you will be fine. Ford used to not recommend Mercon V but they now say that it is acceptable....go figure. Hopefully Mark Kovalsky will chime in. He is THE tranny Guru.

Next time, why don't you try flushing the tranny...it takes 20 quarts to do.

Ford stopped licensing MERCON and changed MERCON V to be compatible with older transmissions. MERCON V is now the right fluid.

Your trans was designed to run on MERCON, so using MERCON isn't going to hurt it at all.
