I have to disagree totally. An AOD with 4.10 gears, shift kit, 2800 rpm plus stall converter, etc... will still lose to a 5 speed any day of the week.
The AOD sucks up major horsepower to operate, and is not efficient.
Are gears, converter and shift kit going to make up for the lost horsepower required to run the AOD. No way.
