I'm not the one with the Fusion, but some of these posts are 3 years old.
If it was me, I would contact Ford directly, not the dealers, and see what
their offices have to say. As for my Escape: I drag raced a V10 Toureg
yesterday and kept up with him for awhile. :-) Smooth shifting all the way
with my synthetic BG (car calls for Mercon ONLY).
Then use what they say. The post started with Mercon, which Ford claims
they don't make anymore. So, that's why the Net is bombarded with questions
about Mercon vs. Mercon V. What do you do when your owner's manual and dip
stick say to "ONLY" use Mercon, NOT Mercon V? Hence, the mysterious service
bulletin that's so hard to find. If they sill make FNR5 ATF that's what I
would use, unless I could find a substitute that meets or exceeds it from a
reputable company, and after a short search I can't find anything as a
substitute. At least you can find what the car calls for.
Actully the post started out with Mercon V being used in a transmission that
Ford says requires FNR5 (apparently the same as Mazda M5 ATF). The Mercon V
for Mercon debacle, while of interest to many, is not directly related to
the orignal post. The 4 cylinder Fusions use a Mazda sourced automatic
which uses a different ATF than other Fords.
The whole ATF thing is way out of hand. I have a 6 cylinder Fusion that has
a Aisin 6 speed automatic that uses one type of ATF not used by other Fords.
It is claimed to be the same as some Toyota ATF, but Ford calls it "Premium
Automatic Transmission Fluid." My F150 has a ZF sourced 6 speed automatic
that uses what Ford calls Mercon LV. Ford still sells new vehicles that use
Mercon V. And finally the new Fiesta uses a special fluid called "Dual
Clutch Transmission Fluid" in the computer shifted dual clutch automatic
transmission they have as an option.
It is not just Ford that is pulling this stuff. Toyota has at least two
different ATFs depending on the year and model of transmission. And my old
Nissan Frontier called for a very specific ATF that was not readily
I no longer trusts shops to get the right ATF. I go to the dealer and buy
the right stuff and take it with me to the shop doing the fluid change. And
surprisingly, it is not always easy to get the dealership to come up with
the right stuff. When I had the fluid changed in my F150 it took a week for
the dealer to get the correct fluid (the Mercon LV). They said they never
used that - they always used Mercon V.....scary coming from a dealer.
I do wonder about the Mercon V for Mercon recommendation since for years
Ford said to not use Mercon V in a transmission that called for Mercon.
