i need more info on this...The Allison trans behind the Duramax is the 1000 series. Good thing about that is that the 2000 series internals will work in it. The 2000 series trans is much stouter. We have put 100's if not 1000's behind Cummins, Cat and MBE diesel engines at work. Up to 400hp and 1200 lb/ft torque. They are stout trannies.
