The thread was from 2005, so present isn't exactly correct.

I just got off the phone with ZF and here's what they told me:
The following years and engines use the "Standard Torque" version:
2002- present Ford 5.4L, and 6.8L
1999 - 2003 7.3L Diesel
2002 - present GM (6.0L) , 8.1L and 6.6L Diesel
All these transmissions have the same internal components minus input shaft differences for 4x2, 4x4, diesel/gas, bell patterns etc... which are rated at 520 Ft./Lbs.
The following uses the "High Torque" version:
2003 1/2 to present Ford 6.0L diesels that is rated at 570 Ft/Lbs.
The difference isn't in the actual component size or design but in the tooth cutting/finishing method used on the High Torque versions which yields a higher torque rating. So the gear set has a "smaller" torque rating on the Standard-Torque version than the gear set on the High-Torque version.
Your friend with the Duramax has the exact same internals as your 2005 V10, minus of course the ATF cooling pump and circuit. (GM doesn't use that feature.) You still have differences in bell patterns, which is integral on these units and you may have differences in input/output shaft dimensions too.
PS: As a matter of course, ZF does not recommend that you exceed 520 ft/lbs for the "standard-torque" S6-650 and 570 ft./lbs for the "high-torque" S6-650...
PS #2: You should have bought a diesel. Real men use diesel...

there are a lot of guy's making a lot more power then what you have on a hand shaker and there still rolling along..i didnt see fuel mod's listed in your sig...spend your $$$ on a good full fuel system (tank to injectors then back to the tank) to keep them injectors alive...every time the PSI drops your loosing power and adding wear to the injectors..
