I added a 13x17 inch cooler to my 2002 power stroke van and saw a 20 degree drop on highway and more when pulling in the hills. My 2000 ford dually now has a custom built transmission and pulls our toy hauler at 165 to 175 degrees consistently without additional cooling. The custom built unit has Amsoil race fluid and the stock unit has regular fluid, no synthetic. I was told not to use synthetic in a stock 4R100.

Expensive on the frequent changes, but I have a stock Ford 4R100 with 156,000 trouble free miles behind a tuned 7.3 (knock on wood). I would change it any time it has been hot.
djtho1 - I tow a Flight 32BHDS with my 1999 7.3 Power Stroke. Recently upgraded my transmission cooler from the smallish stock 7.3L cooler to a much larger 6.0L cooler. Towed last weekend in the Hill Country and didn't get above 170 degrees (around town driving is around 150). Heading to Wyoming in July with family (Grand Tetons and Yellowstone NP). That'll be the real test.

On the 2000 dually I also changed out the 7.3 cooler for the 6.0 cooler. I pulled a 32 bhds with our 2002 4x4 van with the 7.3 with no problem on the highways and with some elevated temps on the hills when I had to climb slow, but the temps came down quickly. With the truck I am pulling a seismic 3712 (about 19,000 lbs) and have not yet seen temps above 190. On highway it stays consistently at 165, and that was from Ohio to California. That is with the custom built tranny though. My stock unit ran warmer than that. Safe travels!

Amazing! That toy-hauler is a beast!

I ran a scan gage on my 05 6.0 ford and I like to monitor coolant and oil temp. Usually a ten degree difference . This let me know of any failure in the system before anything burned up . They were known for EGR failure. Scan gage is a nice tool to have and can monitor a lot of engine functions

speaking of fluid swaps, on my old sprinter based class c, they recommended flush and service of transmission at 50k. The guys at sprinter source said that most of the rigs with transmission issues at 70k, had used the factory specified service interval. Wonder what the average tranny temp was on those rigs.

Glad I found this thread. My trans temp has been my biggest worry so far. On level ground and 60MPH, pulling about 7K, it averages 180ish. But when I slow down through towns, it creeps up to 190's to as high as 210 so far. But it's only been that high for 5 min and a few miles. My biggest fear is getting stuck in traffic due to construction or a wreck and having to creep for miles. My burb has the factory trans cooler installed, And I've only towed about 400 miles this year. Should I look at getting a larger trans cooler? Or am I good to go?

You should be ok. The temp will rise when there is no airflow over the cooler. You coolant temp also rises until your fan kicks on. As long As you are below 225 you're ok. If you are still worried though, instead of a cooler check and see if you can get a dedicated fan on your current cooler. Its all about the airflow. Oh and make sure the fins are clean on both side. Your temps sound right in line with what I see with my suburban.

That doesn't seem excessive to me, I came across a mountain last week with mine and I checked the temp at the top of a 7 mile grade and it was 209.
