I would think that the stock tranmission should be the 4R100, which is the heavy duty Ford overdrive automatic. However, they may have used the light duty 4R70W with a 4.6 engine.

The 4R100 is internally similar to the Ford C-6 (used with high HP engines in the 60s and 70s), but the 4R100 includes overdrive and is computer controlled.

The 4R100 was used with the supercharged F150 Lightning, so it should hold up to the HP of the Cobra engine.
