Mercon ATF

I had my wife's '00 Taurus in to the dealership for a Tranny flush 2 days ago and was told that Ford recently issued a statement telling the dealerships to us Mercon V - exclusively! That is; to use it in place of Mercon and Mercon III in all applications. Does this sound right? Has anyone else heard this? My Expy calls for Mercon III, so should I use Mercon V?

It's true, and according to Ford, yes, you should use Mercon V. I'll try and find a link to the TSB and post back.

On second thought, Please refer to the chart in the TSB linked here:

The TSB at the V8SHO site has specifically been superceded by the now one.

projectSHO89, thanks so much for the information that you provide. I stole the link from the thread that you mentioned. Hopefully this will come in handy for somebody:

This is interesting development. I remember reading about members in this forum panicking and demanding from dealership service shops to flush Mercon V out of their trannies upon learning that V was used when the dipstick and manual calls for just plain Mercon. And there were lots of talk regarding this subject in this forum, how V can mess up your tranny, yadiyadiya. So what now? Should I go V or use Mobil 1 synthetic (which is Mercon) as I planned next time I flush my tranny, since my dipstick and my manual call for Mercon

Thanks for the info guys! The TSB says you can now use dual use fluid (MERCON/MERCON V), even though the manual says: "Using the dual use fluid will cause a hail of hell-fire to rain upon you" (or something like that). It sounds like a go-ahead to use Amsoil, Mobil I or whatever to me...
