    Buddy at work is looking at an 01 DMAX 2500HD,,,,,he was searching around trying to find if it has an Allison in it, but wasn't sure. Told him I know just the place to find out, hehe. So, I know the Alli was intro'd in 2001 but was it standard, an option, standard with the DMAX only etc etc any help is appreciated, thanks guys.

    It is standard behind the Dmax since 01. The 4L80E wouldnt be able to handle what the Dmax can do. Plus look under it, that Allison trans is much much bigger than the 80E

    If he was to crawl under the truck, he would also see it says Allison right on it.

    An Allison is the ONLY auto behind a Duramax in a pickup. 4L80 in the vans
