Does the 1500 come with traction control?

[Lumpy]

I know the truck comes with a G80 locker on the rear so I'm not sure how stupid this question is but does anyone know if the refreshed '22 Sierra comes with traction control?

I am coming from a 2007 Honda Civic which is pretty bare bones. No TC. I am not familiar with modern vehicle stability control systems on cars and trucks.

But my Aprilia motorcycle has TC as so many modern motorcycles do now. It literally keeps the wheels that are getting power (rear wheel on a moto obviously) from slipping at all when dialed up or too much when turned to a lower setting. In the moto world this stuff is constantly being updated and improved with new better sensors, faster processors, more customization for the user etc.

I figured there was at least a rudimentary system in place at when driving in 2WD. However I have broken traction twice now on my truck while on the throttle. The first time was in snow the day after I picked it up. I put it down to being in a lower traction environment and me not being smooth on the pedal yet. There was no drama or loss of control, just rear tire spin.

But it happened a couple of days ago while merging onto a freeway as the rear axle got a little light. I was maybe 40-50% on the throttle at probably 25-30 mph. Rear tire began to spin but again in a straight line with no drama. I see there is a stability control button and assumed it had integrated into it a TC type function but is that not the case? There didn't seem to be any intervention from the truck.

I let off the throttle to get traction back so I am not sure if there is no TC, if I corrected it too quickly for intervention to take place, if intervention took place and it's so natural feeling I didn't notice, or if nothing happened because the truck didn't get out of shape so the stability control just let it go (like in a straight line it allows a certain amount of wheel spin before intervention).

So does anyone know if and how the TC works on a 2022 AT4?

Thanks.

Oh, there is traction control. Yes, it is way better than it used to be - by better, I mean not so aggressive. And also far more useable.

Let me explain better. On my trucks from probably 2008 on (could have been a bit earlier, don't remember exactly when GM trucks implemented traction control), traction control sucked the life out of a truck IMO. I believe it was implemented as much as a way to save transmission problems the car makers would have to address as much as with safety, early on.

I used to do whatever "trick" I could find online to disable traction control. Even my 2014 Sierra Z71, the traction control was so aggressive, even with it supposedly turned "off" with a long 3 second press of the traction control button, that it made me get stuck many times here in Montana, where we have 8 months of heavy winter weather/snow. I remember an old trick was simply to unplug one of the front brakes anti-lock brake sensor wires. That would completely disable all traction control, which meant the 350+ horsepower the 5.3 engine was making, could actually spin the tires without traction control kicking in.

Nowadays, traction control (and stability control) are much more refined. You can actual "mostly" turn off traction control with the traction control button. I say mostly, because it is not completely turned off. It will only allow limited spin. And stability control used to almost cause more problems than it helped with. I don't need a nanny driving for me. Stability control is a lot better now than it was in years past, also.

You have to get to low range 4x4 to have traction control completely off. I haven't totally tested this on my month old AT4X, but I think it is still the same on the X as the regular AT4. The X has full lockers front and back, but you have to be in 4x4 low to get to full lockers on both ends. Which then means not as fast of wheel spin in 4x4 low (wheel spin matters when stuck in snow at times). But the AT4X is the fist GMC half ton with full lockers on both ends for a long time (at least to my memory). Having full lockers is an advantage, obviously, but limited to 4x4 low range, for a reason.

So yes, these trucks have traction control and stability control. Both systems are far better than they were 8 years ago for example. Still hampers the full capability of the truck IMO, but also they are now both useful in a way that adds more safety now, than in the past.
