In all truth and honesty, most of the current highly-frictioned modified ATFs "work well enough" in any application.
At the elemental analysis level, and at the viscosity level, a Mercon V looks pretty much like the 3309 used in Aisin automatics, like the SP III in Hyundai/Mitsubishi/Kia, like the ZF LT 71141, and so on.
The Chrysler stuff seems to have big dose of Calcium which shows up in an elemental analysis, but Exxon Mobil recommends its Mobil 1 synthetic ATF - which looks like the Mercon V - for Chrysler applications.
Once they're out of warranty, you can pretty use anything you want.

How do you know....

As said before on this forum many times...using a fluid not spec'd by the mfgr can over time cause problems with the clutch composite material. usually not noticable right away and in some cases it doesn't happen but the cost of a trans versus fluid is definitely not worth it. I would shop for the dealer fluid instead. JMO
Well, I'll put it this way - the XJR I had with the Mercedes W5A580 transmission specified an LT 71141 fluid in the owner's manual as the service fill. Long ago, I dug around that number on the internet to see compatible fluids, since the Jag stuff was nearly $30/L. Enough sources listed the LT 71141 fluid as the stuff Mercedes used (for the same transmissions in their cars), with all the M-B/Audi/BMW/Dodge/Chrysler OE part numbers that I concluded the Mopar ATF+4 was the same fluid, and the least costly. Plus it smelled the same, which anybody who's smelled the stuff will agree the FM package in that fluid has a distinct odor. It was good enough for my logic, and my car never suffered any mechanical failures...

It's not even the same chemistry!

""smelled the stuff""
Whitewolf this is a new ASTM test routine. LOL

I would consider a flush and fill with ATF+4 good practice.
Seems to work for perfume.
