Transmission Overheating - anyone else?

My transmission temperature raises when I drive a trail in 4HI slower than ~15mph. I have to use manual transmission mode or 4LO. In this case temperature stays in the middle of the gauge. To me this feels weird.
I have around 8400 miles on a 1958 model and it has 3 oil changes on it never a overheating issue
This is because the transmission is anticipating a gear change. The anticipation cause clutch and torque converter slippage which increases tranny temperature.
The 4lo just keeps the LC going slower with higher RPM. The LC isn’t anticipating as many gear changes which in turn keeps the tranny cooler.
Today we drove a fairly steep trail up to Cerro Gordo, about 4600 ft in a little under 8 miles. Lots of washboard and twists, but mostly just steep. In 4 Low the transmission temp gauge stayed right in the middle of the range. In 4 High it would trend up a little but never got to 3/4th of the scale. I mostly used 4 Low. On the way down I used mostly 4 High and hill descent control, nothing that had a gauge got very hot. I wondered about the brakes...
When its in 4LO, and you're driving parts of the trail that don't need it - do you leave it in 4LO? The RPMs shoot to the higher end, seems like that would overheat things no?
Anyplace that felt like I should be going over 15 MPH I used 4 High, but that wasn’t very much of the road. Nothing appeared to be overheating in 4 Low.
