Allison Transmission in a Dodge

Does anyone out there have an allison transmission in there truck or know anyone that does. And if so how is it working? I've always thought that a Cummins with an Allison transmission would be bulit proof.

48RE's to be exact. You do have a point though, Allison 1000 is way over rated and extremely expensive to build.

An Allison is about the same cost to build as a Dodge trans, even cheaper. Fact.
An Allison has larger shafts and can go to ~7-800hp or so on stock shafts. Fact.
Dodge trannies really aren't that common of a swap in Duramaxes. Fact.
The Allison can hold well north of 1000hp built. Fact.
The ones you see are usually 47re's with 48 internals. Fact.

Let's not BS ourselves, pretty much a wash IMO. Stick with the Dodge tranny
