From my limited knowledge it's programmed differently and has a different torque converter. Mustang's are tuned to operate differently than an F150, for obvious reasons.
The problem with the 6R80 is that it began it's life as a 4R70 4 speed. They used the same case, but they made everything a lot smaller to jam 6 drive gears and all the associated mechanicals in it. There are already known issues with them having to replaced the intermediate clutches from a 6pad to 8pad design to help reduce down-shift bumping and shuddering.
Now I'm going to wait for all the Mustang people to chime in with their "but but but the 6R80 can take over 500hp". Potato's |= tomato's.
