TBC Fault??

My 2005 has towcommand and this fault is addressed in the owners manual..It only flashed on my dash 6 different times during the coldest of weather (-15f). I was not towing anything, just driving to work. There did not seem to be any lasting problem after the cold weather broke. Of course the truck is under warrantee but I have not had a chance to get it in. Any one else have this TBC fault notice when you weren't towing? Once tax season is over I will get my baby in for its first look-see at the dealers.

TBC fAULT

Well i have the same problem with my 2005 f350. The message center started showing tbc fault. I took it in to the dealer and they said it had to do with a 2 amp fuse under the hood. So they fixed it and i took it home.
Well when i drove it the next morning and it flashed TBC Fault again so back to the dealer the next day. They have had the truck for two days and still havent fixed it. I broght it home for the weekend and will gave it back to the dealer on tuesday. Anyone kmow the the fix for this. ???

Thanks
