So then how hot is too hot? My tranny in normal driving/towing runs just under 200 degrees, like 196/198 and has since it was new. I take that as the normal operating temp. Going up some hills it has been up to 210, not a big jump up off of normal. I have a '14 Silverado with the 6 speed electronic trans.
The only Ford I have owned was an old Courier, small pick up with a manual tranny and I don't even remember the model year. I started hearing a whine come from the trans and knew it was a bearing going out, took the trans out myself and took it into a small service shop. He told me it was a good thing I got it in to him 'cuz it was ready to go and would have destroyed the rest of the gears if it had happened while driving. Put it back in and drove that truck for 2 more years. Lesson is to know your vehicle and its sounds and how things feel, pay attention and don't drive like a fool and expect things not to break.
