Had to do a repair up in the mountains today. Took the F550 service truck. I was always told to keep an automatic transmission below 200F and that above 200F transmissions won't last very long. I do not beat on the truck.
I'm actually trying to get it's average mpg up. I guess ford knows more than I do about transmission temps.
It stayed this hot and even hit 230 for a moment.no bells or whistles came on and the trans temp gauge stayed in the middle range. It took a good 20 minutes to cool back down to 200-205 on flat ground.
