I actually tried to talk the inspection guys out of dyno testing my truck for smog a few years ago (just cause I didn't trust that they knew what they were doing...didn't want to carry my driveshaft home in a basket). Anyway, I mentioned how I have the autotrak and they said "no problem, we won't take it out of 2HI"...I guess they were a little smarter than they looked

Know that I think about it, auto-trac on a dyno is a big liability. If you accidentally hit the 4hi button, The truck will try to rip itself from the dyno when you lift off the throtttle.

I was browsing the show room at the time of buying my GMC truck and i seen the sticker on the AWD Denali's only. The Denali and most AWD GM vheicles has no transfe-case control in the cab. Its all done "automatic". So i can see the reason for the sticker. But on just a 4x4 pickup, should be no prob dynoing.

Manuals are shift on the fly. I prefer the manual over the electronic shift.
