Please allow me to apologoze for asking this question. I've searched hundreds of articles and forums on the internet. And there all up in arms over what is the reccomended fluid? Myself I'm looking at some Amsoil. But I'm confused as to whether its supposed to be filled with gear oil or Atf? My hanes manual states 92 and earlier 4 speed transmissons use sae 80w gear lube while 1993 and later 4 and 5 speeds use Mercon.. which confuses me even more because I have an 90' 5 speed... Any suggestions? Or facts for that matter?

M5OD uses regular old Dex/Merc ATF. Takes a little over 3 quarts if I recall correctly.

The owners manual for my 91 says to use Motorcraft MERCON automatic transmission fluid, for the 5 speed overdrive transmission (Mazda-R2).

You would really think they would use something a little bit thicker than automatic transmission fluid, but they don't. I would have asked the same question when the time comes for me to change my transmission fluid

I know.. Everything I read says somthing different. The recommendation from amsoil says to use there torque drive transmission fluid

Would I use motorcraft friction modifier with mercon v also is in the m5od r2?

I highly doubt it.

I use Royal Purple ATF and it works great!

No. The friction modifier is for differentials with a limited slip.
