Yeah if it doesn't say allison, it doesn't have it. They use that as a selling point as much as they can. And for good reason, the Allison is a very very good transmission. The best automatic transmission out there for light duty and even medium duty trucks imo

My 2004 2500 HD had the Allison and it was great. I am getting a 2016 and wondered what model # the heavy duty transmission is.

Then you had a diesel or a big block cause they didn't put the Allison 1000 behind a 6.0 gasser in a pickup

They did in a stepvan like Workhorse use to make where a PTO was required.
