The aforementioned F150 has a gauge as well as a readout.  So far, it
runs about 195 F on a hot day just moving the truck.  At that
temperature, the needle sits comfortably in the middle of the gauge
range.  But it's not really a conventional automatic, as I understand
it.

In my dad's motor home, he would let it idle when the trans temp got over 250 F.

I suspect the properties of the ATF you use would give you some
insight on where you might need to ease off...
