  1. just got a new 21 dmax and still learning about this engine. is it possible that it is stuck in regen mode and cant complete it because of the cold weather
  2. will be picking up a 2021 gmc denali 3500 dually today. just a question on break in. this truck is going to be pulling a 6 horse trailer, should i put some easy miles on it first or is it safe to just put it to work
  3. look for something that loose, may look like flicking but could be light is vibrating
  4. same as you, hopefully Phil from harnessdoctor will see this post and make a suggestion
  5. 55577568 Part:Drain Plug
  6. i have the same problem, hope someone has a suggestion
  7. https://www.hoonigan.com/collections/all/products/superchips-flashpaq-f5-tuner-chevy-silverado-4-3l-v6-2006-2018?variant=31887275458645 This will let you turn off dod and correct your tire size. check ebay for refurbished units, it will be half price
  8. that is a strange one, google gm drive cycle and try that
  9. it is to prevent the plastic from rattling against the windshield , not a seal
  10. start by replacing the oil pressure sending unit, it is just below the throttle body.
  11. towed a tandem axle enclosed trailer last night temp got to 122, will see what it gets to loaded today
  12. you need to get the codes read and post them, there are few different things that can cause that problem
  13. if you can just lean your summer tire against the side of your truck and see if you can relearn them, if you can then you know you have bad sensors in the winter tires
  14. the temps here in ontario have been 20 to 30 degrees and my tranny runs at 104, in the summer when it was 80 degrees it ran 160
  15. as dumb as it sounds , i read another post on this problem of using aftermarket cats and the solution was to put oem cats on and the problem was fixed
  16. vcx nano for gm is the cheapest way to go. it is sometimes a pain in the a%% to get it to connect , but works really well. i use mine a lot
  17. lots of videos out there to watch, i just flipped the inside parts. i have 130k miles on my truck
  18. it is been stated many times, until 2014 every gm truck ran without the thermostat with no problems. i live in canada and removed mine, dont notice any difference in how the transmission works
  19. would help to know what year it is, but if it is 99 to 2006 some were known to rub through the wires for tow haul mode. take the plastic cover off the steering column and look at the wires going to the switch
  20. dont know how to really describe it, moan, groan or drone. it only happens between 1600 and 1800 rpms. does not matter what the temperature is when it does this. the rpm's hold steady. i only hear the noise when accelerating , every gear the noise starts at that rpm range. anything above or below and the noise is gone.
  21. sounds like high pressure pump ticking
  22. need a better scan done, need to see the freeze frame data of when the cel was triggered. your symptoms point to an injector problem, but you need to have a full scan done first
  23. did you replace the screen type filter, remove the oil pressure sensor again and then remove the filter in behind it
