zieg, can't tell you if its the same however in 03 i ordered a 8.1l with manual six speed that hauled axx ,when driven hard the clutch would slip (bad) eventually 6k miles the clutch went and at that time there were no upgrades for it because the tranny had an intregal bellhouseing and there was no way to increase the clutch size to match the hp. Not sure how many ponies you are running but it may be a concern. Other than that its a great tranny. hope it works out for you!
