I tow my boat alot. Tow/haul mode it inept to say the least. I was pulling a few weeks ago and noticed that the engine was at 1500 rpm in 8th gear..WTH is that! I use tow/haul in "L" now and keep it in 7th to keep it in a better power band pulling and less stress on the tranny. Pulling a 2.5k lb boat.
Using as designed IMHO. I use M/L depending on driving conditions. It's like the first GM engineer programs the trans for correct operation, then the epa/mpg engineer comes along and fubars it.
