“Mixes” with the charged air?! It doesn’t mix with anything. The intake air gets pressurized in the compressor side of the turbo and heats up. The colder it is going in, the colder it is going out. You’re asking more from your intercooler with hotter intake temps, leading to quicker heatsoaking...
You think each tire is exactly the same diameter and they’re all spinning at the exact same speed? Even going in a straight line, 4H on dry pavement is unnecessary and causing stress on your driveline.
Metal contracts when it’s cold and expands as it warms up. It seems as though cold temperatures contract a part/parts enough to cause a tolerance issue and initially expose the sound being heard. That’s my guess at least.
Mine started doing this with 8k miles now that it’s starting to get below freezing. Noise stops once pressure is put on 6th gear or it’s in 6th gear. I’m waiting for an actual resolution to come out, rather than replace it with another transmission with bad bearings.
Did you get the mid package? I have a 22 Badlands with Mid. Does your door handle have a little bump you can touch that’s supposed to lock the truck?
