I think you may overestimate the effect of wheelspin on acceleration times. The torque converter slip duplicates wheelspin to some degree. Also, wheelspin effects aren't relevant to actual daily driving.
Anybody seen the acceleration curves/data points compared between manual and auto?

From what I rmeber gears 1-4 are the same. 5 and 6 are taller. It is the taller final drive gearing that make it slower to accel a bit.
And for the other, the tranny was thought to be isf based but is actually is350 (edit: is250) based.
