My 04 silverado 2500 w/6.0 did something funny the other day while pulling a trailer. I was pulling an 8 foot trailer with brush on it through my field and had to put it in 4 high. Well I left it idling for a few minutes while I jumped out to throw some more on the trailer and all the sudden my trans temp gauge and reg temp gauge spiked and the DIC told me coolant was overheating. It's never done this and all my fluids are level. I have pulled heavier loads than that with no problems either. I took it out of 4 high and let it sit for a while and then in went back to normal and has been ever since. Any thoughts as to way it would have done that while in 4wd?

Your trans fluid also passes thru the side of the radiator. It uses it to heat the trans faster in cold weather.
What I suspect is that maybe the thermostat stuck causes the coolant to get hot thus heating the trans fluid rapidly with it.

When my thermostat stuck on my truck it did the same thing. (i have no trans gauge) but when i let my truck idle it would overheat the coolant.

Correct it only did it in 4wd. I haven't tried it again without a trailer but I will do it ASAP to see if I get the same results.
