Transmission?
i was driving my 13 F150 XLT w/ 80K mikes this weekend when I noticed my Transmission fluid temperature gauge getting dangerously close to red. Checking the digital readout on the dash showed a temp of 242 degrees. I can't speak for miles 0-58k, but I have never used the truck for towing. Wondering what could cause this? No other symptoms like slipping, noises, or any other normal transmission issue. Anybody got any ideas? Thanks.

Likely a clog in the coolant lines or aux cooler. Can try disconnecting them on the side of the trans and running 10psi air through it. See if it comes out the other line. If it doesnt disconnect the lines from the cooler and radiator. Check lines individually. If nothing comes out you got a clog in the lines. If it does come out you likely have a clog in the aux cooler. Try 10psi there also.
That fluid is probably toast tho. Not a good idea to run burnt trans fluid. Drain pan, replace filter (normally comes w new rubber pan gasket) replace fluid
Be sure to hit the lines w PB Blaster before trying to break them loose, they love to seize up and break. Similar to brakelines.

Temp would get to around 240 and then fan would come on and stay there. That was on a long trip though. I have not let it get that high since my daily commute is only 5 miles round trip.
