My 99 runs 195-200 on daily use. I've seen it go 215 on long freeway inclines.
I added a small additional trans cooler in line with the factory trans cooler. I mounted it in front of the factory oil cooler. This was due to my aftermarket front bumper partially blocking airflow to the oe cooler.
I'm thinking about getting a third core added to my factory radiator.

That's exactly what my 3.5 sport runs...factory gauge seems to run high which freaks me out on occasions.

My gauge never goes past, just below half way mark.

I think I run a bit cooler, in the 190 range.... the last trip you and I were on, climbing up the east side to Cerro Gordo, and climbing up to Lee Flat I was hitting near 220, the gauge did go up, but didn't go past 3/4. I think I was low on coolant at the time which probably contributed to it. I could hear my coolant boiling in the radiator.
When I did a trip out to WY and back last summer pulling a small pop-up camper, going up some of the big inclines, when the engine would be 4k RPM to keep me moving up the hill, I would see the temp gauge go up... but it goes up to a certain point and stops there... as soon as the RPMs come down, so does the temp.
I do like the idea of adding a 2nd trans cooler... I find that if I'm motoring around in the mountains, if I don't shift to "L" my trans temp warning light will come on. because at low speeds the friction in the torque converter heats up the fluid... shifting to L seems to lower the stall speed on the converter causing less slip which creates less friction which creates less heat.
Adding an extra cooler + an electrically controlled fan seems like a big (and fairly easy) win for low speed desert driving
