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...

IF it hurts MPG it would be so small as to be nearly undetectable.
At cruising speed the torque converter would be locked whether in T/H or not. The RPMs would be the same. The shift points wouldn't matter because it's not shifting.
When stopping, starting, accelerating, etc. T/H off may give the mentioned nearly undetectable increase but that's not the point. T/H mode is the proper mode according to the designer of the vehicle for the situation. It provides better acceleration/deceleration and less mechanical wear on the vehicle. I wouldn't sacrifice vehicle control and longevity for .1 MPG.
described perfectly!!!
