Type F/FA is the old Ford tranny fluid specification.

Mercon is the new (1987+) fluid specs for Ford tranny fluid. The newest being Mercon V.

So no, Dexron does not equal Mercon. They are not the same. They can not always be used interchangeably. So please, please, please, don't offer wrong advice.
Why does Mobil of all companies sell one that does both and not one for each type?
