Oil in coolant

[HSKR R/T]

He didn't specify what kind of fluid he added 5 quarts of. You assume oil, I assumed trans fluid. "As well" when taken in context could mean more than one thing. I took to mean they found trans fluid is leaking into the radiator, as well as what spilled onto the ground. Fun with English.

English is fun. Since the transmission leak wasn't mentioned until the end of his follow up post, and he was initially talking about engine oil, it's safer to "assume" the 5qts added was engine oil. His would have been complaining about severe transmission issues if his transmission was 5qts low

And that's the problem with assuming things. OP and most of us were assuming it was engine oil, but that was never confirmed. Then the shop said it was trans fluid. So why are you still stuck on engine oil at this point in the thread?

Jeeze guys. What is in a worse state this thread or OPs poor truck?

Shop said it was leaking trans fluid "as well". And as I already mentioned, if his transmission was 5qts low on fluid, he'd barely be able to drive it, but since no shifting issues were mentioned, it's pretty safe between he added engine oil. I'm not "stuck" on anything. You have just dismissed it without any confirmation.

It was 5 quarts of oil. They couldn’t determine if the oil was leaking as well because everything was soaked in fluid.
But here’s the attached findings they told me

Thanks for clarifying. So your truck leaked 5 quarts of oil onto the ground and also is leaking trans fluid into the cooling system? Damn, when it rains it pours. Would be good to know where the oil is leaking from.

That’s the confusion… idk where the oil is leaking too cause it’s all a pretty mixture coming out of the overflow for the radiator

It would be really inconvenient to add 5 quarts of transmission fluid, since there is no dipstick fill tube he'd have to crawl under or jack it up.

In any case, hope they found all the leaks and some good flush and refills get it back in service.

A failed inter-cooler?

Yeah inter cooler failed transmission cooler failed and radiator failed is the easiest way to sum it up but on the bright side they put a 36,000 mile warranty on it

For no other reason than being bored I decided to unscrew the radiator cap on my 2019 1500 Limited (5.7 Hemi, w/e torque) that I just bought about 2 weeks ago with 63k miles on the odo. Noticed the jam like textured gunk on the cap and residue of the same stuff on the expansion tank dip stick (but only on the mid to top part not the submerged bottom part). The coolant looks to be a brown/orange color, definitely not healthy looking.
Went to the dealer in my town today and asked about previous repairs and they said that transmission lines (fluid lines/coolant maybe, they didn't specify) were replaced under the previous owner's tenure.
I ended up buying 3 gal of concentrated Mopar coolant and about 10 gal of distilled water, planning on doing a flush tomorrow then a refill with the correct coolant/distilled water mixture and see what happens.
We're planning a 5k mile trip to the East Coast from interior AK in a few months and I'd like to get ahead of any possible issues.
Has anyone dealt with this particular issue? I have read here that a few oil-coolant heat exchangers on 2019-2021 YM have had issues but haven't seen what the contaminated coolant looked like in those cases. The transmission shifts fine btw so whatever issue they had there was probably fixed. I'll still do a partial flush on it with about 6qt of Mopar transmission fluid for the ZF 8&9 speed just for good measure.
