I would not be too sure of that, I had fits simply finding a correct specced fluid that worked on my '11 Versa normal ATX not a CVT not 4 months ago. I found plenty of fluids all right, just none with the correct spec listed, all listed the previous one but not the one I needed. That's death with ATX clutchpacks if you happen to be unlucky. There can be multiple spec sets now in only one manufacturer, look at Nissan; they have at least 5 now by themselves.
What I meant about that Mercon issue I mentioned above. Ford ate thousands of torn up ATX when they said the later V fluid interchanged in with the earlier non-V..............then it didn't. Then they sh-t bricks for a year sending out warnings to all the dealers, the fluid had to be all yanked and completely reformulated. Then and ONLY then did it truly interchange, and some aftermarket makers had the bad stuff on the shelves (since they had copied the original 'bad' Ford spec too) for a couple more years as they refused to yank it all. So, lots of transmissions out there died way ahead of time and the owner no wiser.
The difference in Mercon III and V was in clutchpack material only, the V was needed with the new 'high energy' clutch materials and if III used the trans tore up, the move made in the middle of like '98 and tore up more of them. Some confusion though as the fluid flipped to synthetic too. I rebuilt a trans around '07 that used the old clutches previously and had to upgrade to the new fluid with the new clutches, it worked well, trans is still running fine today.
I found that the super expensive 'superfluids' that claimed to run in anything often caused problems, people were constantly bitching about them when I was in parts. My view is past a certain point you can have additive clash there.
And now some are even changing the basic viscosity which has been 10 weight since like the '50s, that alone can easily tilt your shift strategies wonky as the VB
control orifices are based on that weight. So, if say a fluid says it fits the Ford spec both V and LV, well, you won't catch ME using that crap. Buyer beware I say.
Do what you will and what most usually do but don't cry if you get bit. ATX last short enough now as it is as compared to what they used to. I'm still used to 8-10 years or more use apiece and even on the ones I rebuild, I won't be giving up on that.
