Due to gear multiplication, the 650 lb-ft Cummins with the G56 is actually putting down considerably more torque than a SRW 900 lb-ft Cummins with the Aisin in first and second gear. In third, the G56 is still putting down more torque, but not much more. The Aisin is only putting down slightly more torque in fourth through sixth.

Your forgetting about the torque multiplication factor of the torque converter. This will be around 2.0 to 2.5 depending. The auto will kill a row boat tranny off of the line because of the torque multiplication factor.
