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.
I've never seen a bottle of Mercon or a bottle of Dexron, separately. The only thing I have ever seen is "Dexron/Mercon" followed by a roman numeral, depending on what the latest formula is and I've ran it in every transmission I've ever owned (all GM) up until I got my hands on a 4T60E, where I switched to Mobil 1. If it's available in some other way, then that's news to me. Type FA has been for fords as long as I have known. If there's something new, then that, too is news to me. I can't say I know a whole lot about the ford since I'm not on their team, so I won't debate you.

Are you saying you can purchase a bottle of "Dexron" or a bottle of "Mercon" - either one you want? Maybe I misunderstand you. The last case of ATF I bought was Dexron/Mercon IV, I believe. I run it in my 4L80E and my 4T60E. My 4L60E gets Mobil 1 ATF only.
