Button on dash

Button on dash

Postby Sierrablackness2011 [OP] » Jun 13 2012, 12:29am

I'd like to start by saying I've been lurking here for a year since I bought my 2011 gmc crew cab 5.3 z71 with hd cooling and tow package.
Would anybody be kind enough to explain to me what exactly the diff button on the dash does exactly, and how my diff works...? The reason why I'm asking is cause I noticed that when I try to spin my tires in the rain, I can't spin them for long. What I mean is I step on the gas and they spin but soon after it's like the engine dies in revs and the tires gip. Is this normal? I tried with button on and off.
Thanks in advance for any explanation

Diff button? I know theres normally a traction control button.. And to fully deactivate you need to press and hold the button for a few seconds to disable tc and stabilitrac! Then it will spin :) but ide leave it on unless your off road!

Sorry. Yes that's exactly it. The button for the traction control.the on with the squirmy lines under the car. My truck doesn't have stabilitrack as far as I know..... When I push the button it gives me the option of traction control on or off. I still can't spin like I want. I just went out to try a brake stand... Wasn't able to do it. It was like the truck didn't have enough power to turn the wheels freely witch isn't the case with the 5.3 They had a hard time....I also turned a corner while Ste ing on it to spin the inner tire and I'm lucky if I put a 6 foot black mark on the pavement.....

Did you press and hold it for like 5 seconds? Also, with torque management built into these vehicles plus the drive by wire, power and torque at low speeds is computer controlled to eliminate stress on the tranny. But if you press and hold tc button for a few seconds, you should be able to spin!

You have to hold the button for quite a while to get the stabilitrak off.

It's actually more like ten seconds to get the thing off....and yes it will spin for days with the 5.3 if it's unrestricted, particularly with the torquey (is that a word) rear-gear you've probably got with an HD towing package (3.73 or 4.10?). I don't know what the difference is between plain TC and Stabillitrack, but you have to get them both off or the computer will over-ride your pedal inputs and modulate to stop the spinning (kill your throttle basically).

Have fun, just make sure you have cash lying around for new tires.

It's a nanny device. It's doing exactly what the engineers programmed it to do: Destroy your ability to drive how you want to!

Now where's that Trunk Monkey button?....
Marine because.

Thank you very much to all of you. I got the stabi and traction off. But still no spin :evil:
I took both settings off and came to a full stop. I then pressed the brake and stumped the gas and just the slowest of spinning to the point I think I'm forcing something. Now I must say that I have a leer cap on my truck and 265 65 18 bfg rugged terrain tires.. Would that stop me from spinning?? Other way I can explain the feeling would be like trying to spin 33 inch tires on a civic. Just feels so underpowered which I know the 5.3 isn't
