I've only driven it on pavement since I got the trans temp part, and the outside high temps are in the thirties around here. But, given that, it pretty much stays at 152 degrees and climbing a long hill it goes up to 164. This is all at 45-65 mph.
Summer time and slow crawling in the dirt will tell the tale.

I have the X-Monitor to keep track of the most important criteria while towing, and the ScanGuage primarily for the fuel usage/economy information.
Ditto on the X-Monitor and Scangauge (1.0).
My trans temp generally runs in the 150's but I've hit 200 on long uphills. My trans alarm goes off at 190 (I read somewhere that the trans is good through 225) so I was a little nervous and I let it idle a while after parking to bring the temps down and not cook the fluid.

The diesel guru that I once to my SMB to, said to set the alarm at 230. Personally, I'm more concerned about EGTs than trans temp when getting ready to shut the engine down. High EGTs can cook the oil in the turbo bearings. Of course, then there's the debate about at what EGT to shut down the engine.
