It looks like GM did just give us some confirmation that the Allison 1000 is the "weak link". From the article on the new 6500 coming out: "the new work truck will produce 350 horsepower and 700 pounds-feet of torque. The Allison transmission backing up the engine will be available in several versions; pairing depends on how much weight the chassis cab is rated to carry. Those transmissions will include the 1000 and 2000 vocational series along with several other stronger versions to accommodate the expected Class 6 loads that go all the way up to a 22,900-pound gross vehicle weight rating."
Previous versions also offered different versions of the 1000/2000 derivatives too. Other brands like Navistar that sell the Allison trans on trucks, spec the 2000 or 3000 series where appropriate.
