Just add it to all the other stuff that never made sense.
Not trying to dog pile on the OP but it was natural for most to come to the conclusion he messed something up the way he conveyed the problem as he wrote it. He has to own that regardless if the case.
This is the latest gasket and the one you want:

The 2020 and until about mid 2021 models came with different metal plate gasket with a thin rubber perimeter seal and are more prone to leaking.
That is ok, they can still get to pay $500 for a plumber to come over for a toilet that will not flush right to only fish out 4 or 5 Hot Wheel toy cars stuck in the S Trap with a 5 year old that has no clue how that happened.
Here is the special tool for removing the pulley:

You can find the replacement pulley in the aftermarket. MOPAR does not officially sell a OEM replacement pulley and wants to sell the whole alternator with attached pulley.
AI is still having a hard time discerning speculation from fact a lot of times. Reminds me of my 5 year old grandson that will pick up some random bit of minutia information and spin it into some story that took a right turn at Albuquerque but he truly believes it.
Went to a pretty small rural High School where many of the teachers had been students there in years past and came back to teach.
Remember one time in a math class and during some down time between lessons, was mentioning to another student how the wood planer in shop class had a messed up...
Someone with more knowledge of hydraulics would have to chime in as my damage statement "if any" is speculative on my part. I know fluid incompatibility that are not like chemistry miscible can cause problems with seal that may not be compatible and cause mixed fluids to either become acidic or...
You are pissing up a rope, especially trying to mix the pre PUG Pentastars from the JK and prior.
I get it, any engine should go 300K in an ideal world but we do not live in that and is why there is warranties. There is no warranty for the warranty.
If you want a feel for such things, look up...
You got anything besides copy paste of Amsoil study data that was done almost 20 years ago and we have had 4 revisions of API since?
Reads like ChatGPT has written most of this for you rather than a personal articulation of understood fact.
Full flush is ideal, but if not possible, I would just turkey baster suck out,refill with correct fluid, run awhile and refill a couple of more times with the correct stuff and call it good. Damage if any has already been done and would not get too paranoid about it.
With MS-13340 coming onboard mainly for Turbo applications, a lot of the major brands are no longer testing to retain official MS-6395 certification but still recommending their oils for it. About the only major brand still showing MS-6395 licensed compliance is SOPUS products like Pennzoil...
Without a bypass cable, you are going to need a high level scan tool like Launch, Autel or similar that supports having a paid ($60) yearly subscription to Auto Authority that can tunnel through the SGW.
Way cheaper to just get Jscan and a bypass cable to do the clearing. That fault code will...
Probably all of them until the sixth row out and then the Ford and GM rebadging blurs it.
The convertible Mustang and the IROC-Z Camaro look to be about the newest and puts if squarely in the mid 1980's.
