Where have you seen that? All the data I've seen indicates that the only performance differential between the manual and the auto is due to final drive gearing. This would affect the torque output shown on a chassis dyno, so I suppose it could show a different in horsepower based on that, but it shouldn't really create a significant affect. The transmission itself accounts for only a small portion of drivetrain loss.
