4-wheeling

[Dewi2005]

If you did not have the TC2 button on then the traction control (as OrangeCrush stated) would have taken over and applied brake pressure to the spinning tire(s) thus it would seem to 'crawl'.

Next time use either 4H lock, or 4L lock and select TC2 button..

Here's a question, I went out to a mud hill, (pretty steep) about 30 feet long from bottom to top, I put it in 4 high and gunned it, about half way up the Hummer really started to bog down, I expected a rooster tail of mud to be shooting out the rear, I eventually crawed to the top which no other 4 wheeler could but I expected more power, of all the button options would of there been a better one to go up a mud hill? (4 low, lock the rear end?) like I said it really bogged down.

I already had it in 4 high and just gunned it, have stock bfg's on it. the question I have is does the tranny system on the Hummer keep the wheels from spinning somehow, so it would seem to bog down since I was in mud?

Nice bro! These trucks are the real deal. Did you have the locker on?
