Need assist finding a shop manual... (2001 2500HD 8.1/Allison 5-spd)

For some reason, can't seem to find a shop manual (GM, Helm, even a Chiltons or Haynes...) that covers a 2001 2500HD with 8.1/Allison 5-spd drivetrain.
Any help appreciated.

The Transmission and transfer case manuals are usually separate from the service manuals.
The Helm part number is GMPT/01-TURM It's two volumes. I have them but not scanned yet...
Unfortunately the M74 Allison 1000 is not in that manual.
I'd get an ASTG manual for that transmission...
