Seems more and more likely GM is dusting off the smaller displacement version of the Duramax. A friend of mine owns a company that makes gears and other small components for transmissions. Aside from having recently bid on parts for a new ZF 9 speed automatic to be used behind small displacement 4 cylinder turbos to be released for the 2014 or 2015 model years.
He also just bid on some parts for an Allison 7 speed auto with a design limit of 550 lb-ft of torque. Said to be used with a small displacement V8 light duty turbodiesel with approximately 325hp and 475 lb-ft of torque. Volume levels he was given would seem to indicate use as an option in 1/2 ton pickups and full size SUV's.
