2018 2500HD traction control


Recommended Posts

Posted

Hello - New here and just bought 2018 2500HD. Not new to mechanics....just old school and not used to all this electronically controlled stuff.  So I believe I under stand TCS:  it comes on when it senses wheel spin and brakes work to stop spin along with computer dropping engine power.  You can turn it off with button on dash but every time you start truck up it will come back on.  So if you don't want it on you have to turn it off overtime you start truck up? It does not work when transmission is in first gear. Are all these statements above accurate ?  A lot of people have mentioned turning off TCS to do burn outs.  Not that my goal is to do burn outs but when I've turned traction control off it doesn't seem like my truck spins the tire any easier than when TCS is on. How does auto locking differential play into all of this.  I would think it would make it almost impossible to spin tires on dry pavement with stock 6.0 power and locking differential.  I'm sure someone here has more information on this whole situation and can explain and answer my questions.  

 

Thanks in advance!

There should be a button to turn TCS off... read the manual...

 

Yes everytime you start

TCS wors in all forward speeds to the best of my knowledge.

There are a lot of things working against tires spinning on these trucks.... like the lack of torque at low rpm and heavy weight of the truck are the biggest thing. Even if you are 90% of peak torque at 2000 rpm or whatever multiplied by the trans and rear end gears you are still fighting against a 7000+ lb pig of a truck with a bunch of torque limiters other than the traction control on the stock tuning. The gov lock will still operate regardless of the traction control but the traction control will kill power as it sees fit to control wheel speed.  

 

The traction control engages in all gears unless you deselect it with the dash button.  Pressing and holding the button for 5 seconds or whatever also shuts off the stability control however that will automatically re-engage above 35 mph.  4 low automatically disables stability and traction control but not so coincidentally you can't go over 35 mph in 4 low on the stock tune lol.  

 

I would not waste my time with trying brake stands.. you will not overpower the rear brakes.
