Tow haul button
I have a 04.5 duramax 3500 and I'm not sure when to use the tow/haul button on my gear shift also using this will it help my MPG? Thanks.

On another note this was the first time my truck has ever actually worked since I have owned it! It was a different feeling to have the Duramax do anything other than move me along while basically just idling. (I have had my Duramax just about a year). I really love the power and the controlled engine breaking!
The Duramax/Allison is a great package. After towing with it for a few years, no way I'd even go back to a manual transmission. Good luck!
