sounds like a killer truck... I'd chose std tranny over auto anyday.
What if you could have the medium duty Aisin? Its supposed to be stronger than the Allison. I have been looking for information on weather it would work in my 05 Dodge. Then there is the wait to find a crashed truck to buy one out of. My auto has worked fine pulling heavy loads and been through the mountains with it but when the time comes and it will I would like to go back in with the Aisin.
