The Allison 1000 transmission that is used with the Duramax is probably one of the best heavy duty transmissions ever made and unmatched in any other brand truck,
While it may have been underrated and extremely reliable at its rating it is no secret that the Allison 1000 held GM's tow rating back for several years. GM finally had to scrap it and build a new transmission to stay competitive with the competition's tow ratings.
I have an Allison in my motorhome on a Freightliner chassis. It is only rated to pull 5,000lbs because of the rating on the Allison. I have often wished that they had put a stronger transmission in it.
