Settle an argument for me, please!
My buddy and I have been arguing over this for a few weeks and I keep telling him that he is wrong about this. He says that I should not drive with the tow-haul on all the time because it hurts my MPG...

Using A Transmission with Tow/Haul Ignore the "Ignoring the Barking Dogs" article and skip right down to the towhaul article.
With the Duramax I used to just click it off and get in into 6th gear and then click the TH back on and it stayed in 6th gear. You can always speed up a little to get it into 6th and then back right down. I can't imagine that it would do much for mpgs. I do know that with the Duramax/Allison, the tranny would run a little cooler with the TH on when I towed my Montana 3474RL. I'm suspect the same with the TorqShift. I have done mostly all mountain driving so far and i'm getting a little over 6MPGs. Mountains are rough on MPGs!
