7.3 PSD - Ford F350 with the 4R100 AutoTrannny.
Is it plausible / even common for a seized brake / caliper to cause a tranny to overheat? I've never had this occur previously on any vehicle, much less a vehicle like this one which is made to tow 20k lbs and has a rather beefy transmission.
After fixing the brake, I have seen normal tranny temps (70-100 degrees f. above ambient - not towing). The overheat (about 240 degrees) did occur while climbing a hill (again, not towing). Should I still suspect possible tranny issues and if so what exactly or is it more likely this was all caused by the brake seizing?
