Ford's factory rating for the 1994-1995 Mustang GT's goes like this.
215hp, 285lb/ft for the auto.
225hp, 300lb/ft for the manual.
While the tranny should not affect engine hp, the computer calibrations will. I don't know why Ford would calibrate an auto computer that poorly though, especially considering the manual computer is SEVERELY detuned already.
My best guess is that in the real world, the auto and manual cars make the same power, Ford just wanted to cover up for the blatently obvious shitbox of a tranny they stuck into the auto cars. The AOD is the laughing stock of just about every manufacturer outside Ford in the performance world. Sickly inefficient, it cost's the engine about 22% of the power made, compared to 17% by the T-5, and 19% on the C-4. Furthermore, the AOD's shifting is slow, and soft with little responsiveness. Add in a crappy torque converter and you have a recipe for performance nightmares.
Dispite that, the AOD can be made into a performance tranny. All it requires is a new torque converter, a shift kit, and some low *** gears to compensate for it's inefficientcy.
