i do have both trans and oil cooler
I just went through this on my 2007. All of those only have a 1" thick core but your factory radiator has a 1.3" thick core. Summit Racing has the correct replacement for a Denali. Looks for the OEM unit with the core that's thicker than an inch. I'll see if I can find a link...

Interesting, why is this half the price of this one which says fits the 6.2?

I was just going to post this.
This part number has both coolant and oil cooler included and was a direct replacement.
Fit like a glove and their service was actually very good. I had an issue with the first one and they had a new one out the next day no questions.
