Transmission Temp?
So my F-150 has a handy temp gauge that reads in degrees for the trans. temperature. While I realize heat damage to the fluid is a function of time (hot for a long time is almost as bad as super hot ...

Krikey. The 60's trans fluid temp chart that just won't go away.....
I used to run a scangauge, and now an OBD wifi dongle with apps on my iPhone.
The Ford gauge is dampened by software, it has nothing to do with resistors. There are 2 reasons the Ford gauges don't move around a lot. 1) Engineers determined you do not need to know the nuances of trans temp, only when it is rising (and it will register temp changes when it goes even 10 degrees above "normal")
2) Ford has a very thermally stable cooling setup in most of their vehicles, especially their trucks.
If the engine or trans starts to heat up, the temp gauge will increment up. I have found during hard pulls, the gauge will go from 4/10 to 5/10 to indicate that it is warmer than normal, but still fine. During one particularly hard climb at GCWR up a 12% grade @ 6000' asl, the gauges started to move, one increment at a time. Nothing acted up, boiled, leaked or even smelled bad. Peak temp I believe was 250ish when it went near hot. With the latest LV fluid, that is extremely heavy duty, and is rated as "lifetime" fluid, heat is much less destructive than it used to be.
Fords also have " envelope protection", whereby they reduce engine output as required to allow heat to be dissipated without harm, A message appears indicating " power reduced", and things get a little slower. My experience has been that my last 2 F150's were tough as nails, and way more durable than the 2 Toyotas, and 2 nissans that preceded them. That's progress!
