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.

There is no real manual mode on these transmissions. All they do is limit the top gear the transmission uses. They still shift automatically up to that gear. If selected, the tow haul program is still functioning even with the transmission in "manual" mode.
That is one huge advantage that Ford has, true manual shift control. It locks the TC and will not upshift unless told, and will not downshift unless rpm goes prohibitively low.
I use it all the time in tandem with cruise control to keep things smooth, quiet, and efficient.
