To borrow a few graphics:


I would probably go ask a Ford mechanic who is familiar with this decades's transmissions and get an authorative answer. Heat kills transmissions quickly, and even with materials design, ATF is still ATF, and will cook/coke at high temperatures.
If you are continually seeing those temps, I wonder if a transmission cooler upgrade is in order. It might be wise to see about replacing it, if the factory cooler is the same tiny size as pictured on this link:

(Bottom cooler is for the trucks, top for Econoline models.)
