I joined this board to discuss my Expedition, now we are talking about Trannies? I am pretty tolerant, just didn’t expect this.

Gosh, I didn't know Expeditions had transmissions!...I joined this board to discuss my Expedition, now we are talking about Trannies? I am pretty tolerant, just didn’t expect this.
Curious where you all hover on tranny oil temp in your expys. I have a 2017 that seems (in my opinion) to run pretty hot all the time. I hit 238 while towing a few weeks back (~5500# on flat hwy) which had me very concerned, so I recently installed the OEM transmission oil cooler.
I haven't had the trailer out since I installed that, but did some highway driving today and was hovering in the high 190's. (Overcast/rainy day, moderate traffic, air temps low 70's, less than 30 min drive). To me that still seems high.
In a couple weeks we'll be towing up some moderate climbs (Charlotte to Gatlinburg) and I know that'll be a true test. So just overall curious what you all seeing and if this is just normal for these trucks.
Thanks!
dramaticMy 4X4 2016 Platinum Expedition EL (Enigma) has all the HD tow stuff on it, most of the stuff behind the front bumper and grille replaced a year ago thanks to a drunk driver. I have never towed anything with it, but since it seats 8 adults comfortably, 12 in a pinch, done that a lot! 62,000+ miles on it before the accident transmission temp 195 - 205 at 90 MPH or below. Water temp 198 - 201 at 90 MPH or below. After the accident with a new radiator, intercoolers, oil cooler, transmission cooler, electric fans, entire front end, hood, and some titanium brace thing only on the Platinum versions of these vehicles that takes Ford Motor Corporation almost two months to produce! No difference. However, these things hate, loath, and despise slow, sluggish, bumper to bumper, stop, and go driving! In temps over 95 degrees! Even with one soul on board, it's not unusual to see 215 - 225 on the transmission temp and 210 - 215 on the water temp. Like everyone else, and as the second owner of this vehicle, I found this all alarming! Did some digging and found a temp on the transmission in temps beyond 95 degrees in mountainous country with the vehicle maxed out towing a trailer, 330 deg is just skippy! Personally, If that happens to me, I am pulling over! Fer sure to remove the tuna off the seat I would have most likely pooped out cause it actually got that hot! The water temp is a bit different, its a concern at 230+
