Why on the automatic tranny shift handle, do you not see a tow haul mode button like the one on the 2500/3500?

not 100% sure, but I would bet the programming is beefed up to not need the cushy mode that we have. It's in tow/haul more or less all the time.

my '03 is the same way...no tow/haul button. I just assumed it was always in that mode.
