I worked in transmission engineering over 30 years ago. While 250F is pretty hot for non-synthetic oil, it is not "over the limit". IIRC, things got bad over 270F. The simple thing to do now is pull the dip stick. If the ATF is still bright cherry read and does not smell "burnt", ho harm !
If you are using synthetic or even blend you have a lot more room. I think all Motorcraft ATF is semi-synthetic now.
BTW, you did the right thing, backing off.
i finally did pull dipstick,, it is still pink and smells ok. i did notice the dipstick tube holder is quite loose and it was never like that before.
i am sure it is synthetic,,, i ran amsoil synthetic for years until last fluid change when the local shop put their brand synthetic in it.
