transmission temperature
#11
Over the years I have run a number of semi tractors with lots of gauges including both rear axles and tranny temp. None of them were anywhere close to 300*. It's been quite some time since I drove one with full gauges and the current rig I drive occasionally has minimal. So I can't recall where the red line is but I can say fairly confidently I would not be running it very far if I were seeing that type of trans or rear axle temps.

Tranny temps should run 60-80* above ambient air temps...
If its 100 out you should expect to see 160-180*... Towing heavy with the TC unlocked you could see 200-220*
Nothing to get excited about up to about 225* or so, then and only then would I worry about pulling over and leaving the truck running to cool it down (in N or park)
Winter, I will rarely see over 130, Summer I will regularly see 180-190*.
Yes, you can have your tranny too cold and run into issues.

OOOO boy you guys are only getting around 180 degrees on your tranny temp?? Im pushing 200* sometimes. I mean then again I am in cali where it gets pretty hot and pulling a 26ft weekend warrior through some pretty steep grades out towards Glamis. do any of you have any good tips on driving with a load?

Cooler now
I run a 22 foot Weekend Warrior with ATV, Dirt Bike, 110 gallons of fresh water, along with more junk than three families need. It's only about 9k lbs but on a 90 degree day my tranny temps were on the higher end of 200 degrees-F. Last year I pulled the stock cooler and put in a 6.0 cooler (almost 3 times larger). The stock cooler was only slightly bigger than my power steering cooler...I couldn't believe it. Anyway, I pulled my trailer on a 90 Plus day (with A/C running for the wife) and the warmest temperature I saw was 130 to 137 degrees-F. Granted, I wasn't on a big hill but there was an upward grade for a long pull. The extra cooling made a huge difference.
