Is the trans behind the 6.6 an Allison?
No, only the Duramax gets the Allison. You wouldnt want to turn that trans with a small block gasser.
Duramax doesn’t have an Allison anymore either. It has the badge, but that’s about it.
Although I don’t follow your logic. Are you saying the Alli would rob too much power?
They used it behind the 8.1 successfully, which I think had less power than the new 6.6 gas.
