Yes. Mine did not look like gooffeyguy's above. Cover is much thinner and has the 'washer' like above.

My pic was one I just quickly grabbed off the internet. Actually of a Corvette, not a truck, but basically the same thing.
You removed the line the wrong way. It doesn't unscrew, it snaps in and held in place by that spring clip

Do you think any damage is done? Could you explain the risk of coolant contaminating the ATF? That threaded inlet should be 100% attached to the transmission cooler and not interface with radiator coolant at all imo.

If this were my truck, I would change all of the transmission fluid now, before driving it too much. I would then probably flush the radiator and put fresh coolant in there, it's supposed to be done after 5 years or 150K miles anyway.
I almost did what you did once, only I kept reading a little more before doing! hehehe I bought this tool and used it the first time the other day: https://www.amazon.com/gp/product/B00AZW8PDC/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1
I still am not understanding how there’s any path for interaction or mixing of the fluids. How is there a *********** of the radiator water barrier here?If this were my truck, I would change all of the transmission fluid now, before driving it too much.

If you unscrewed both of those fittings, the transmission cooler in the radiator tank would fall to the bottom of the radiator. When you took it out, you compromised the seal, allowing contamination. I've seen videos that illustrate this before, let me see if I can find them...
I know that .... I meant what physical design of the interface between the radiator and the transmission cooler and cooler lines risk cross contamination of the fluids?
But I was able to screw it back in ... nothing 'fell' .... do I need to inspect anything? No leaking fluids that I could see ....

Brian, the cooler didn't fall to the bottom because you only disconnected one line, right? Did you see the o-ring on the outside of the fitting? You will not see leaking fluid between the inside of the radiator tank and the internal transmission cooler, unless you cut it open.
You said the fluid looked "watery" right?, How about some photos for the fellas here to examine and give you their best opinion?
Well Brian, maybe I'm not looking at this right. Tom, Wes, Steve, Joe what do you guys think?
