  1. yes, not carpet but it sure looks like it.
  2. It's wants your On-Star/My GMC/MyChev password.
  3. While they released a DFM disable, it doesn't work on anything with the 10 speed trans yet. Jay
  4. At this point I would measure brake rotors to the frame. Seems to me the truck wouldn't drive straight if the axel was not aligned correctly with the frame. Maybe get someone to follow you and see if the truck is dog tracking. I think it's far more likely the box/cab are off center than the axel being off by an inch. Jay
  5. Does the box look like it’s lined up with the cab?
  6. If the HD you are referring to is the 2500/3500 then it's a 10L100 that has no relation to the 10 speed in the 1500s and was designed by GM & Allison. The 10 speed in the 1500s (at least gas engines) is the 10L80. There is also a 10L90 version in the Camaro and Corvette.
  7. There is a switch on the dash to shut it off. The only bad part is it resets when you shut the truck off. Jay

  9. You need a relearn tool. Changing tire pressure doesn't work on the newer trucks.
  10. I have no issues with my 2019 Denali connecting to my iPhone 11 pro or my Samsung S10E. I agree it's time for a dealer visit. Jay
  11. The TSB doesn't say anything about where the truck is assembled only where they are sold. As far as I know the 8L90 is only produced in Toledo, Ohio.
  12. March 1st 2019 is the cutoff date for the factory fill with new fluid. MC-10163241-9999.pdf
  13. It turns back on at 35mph no matter what. If you have a low range transfer case it may stay off but your speed would be limited. Jay
  14. Take it for a drive and get it above 40mph and then go home and try to learn the sensors to the truck. Jay
  15. The Range unit does both. The old non beta unit would work to disable AFM and the auto stop/start (most recent version). The new beta unit adds the DFM disable. When Range was still a small company based out of Colorado they had a unit meant for fleet use that would only disable the auto start/stop. Not sure if you can still gewt that after they were bought out at the end of last year. Jay
  16. TSB -> 19-NA-121 for 8L90 in T1 trucks. It only applies if your truck was built prior to March 1st 2019. After that date the trans already has the updated fluid. Jay MC-10163241-9999.pdf
  17. The only time I have an issue is when it's snowing and the roads are sloppy/slushy. It has something to do with ice coating or hanging on something. As soon as I get up to highway speed (stuff warms up) or all the stuff melts out from under the truck the issue is gone and the 4wd light is back to normal color. Unless the TCCM is somewhere it can get ice on it thats not the problem. Jay
  18. I agree with the sensor theory. I only have issues when there is a lot of road spay from the melting snow and temps below 25. Once I get up to highway speed the problem clears and the 4wd indicator goes back to white and the service 4wd goes out so ice buildup makes sense. Jay
  19. Before you do anything take the truck out on the highway and get it up to at least 60mph. The sensors are shipped from the factory in a sleeping state to preserve the batteries prior to use. Then put the truck in TPMS learn mode and try again with the tool. I had to do this with my 2019 when I put winter tire and new rims on my truck I got from Tire Rack. The info was given to me by a service manager friend from a Chevy dealer in Minnesota. He said it's a common problem with new sensors. Most of the time spin balancing will wake up the sensors but not always. Jay
  20. I have the most up to date version of Range (from previous company) that defeats DFM about 90% of the time as ls1wolf stated (also kills the auto stop/start). I think part of the delay is that the old Range stuff was produced by a small company based out of Colorado. The were sold or bought out by the same company that owns Edge based in Utah. I did beta testing for Edge a few years ago and would not hold my breath that there will be any DFM defeat anytime soon. Jay
  21. I tried this on my 19 Denali. Left the truck off and locked for 2 hrs. Reached in and opener still worked (key was in the house). My wife's 18 Traverse is the same way. Jay
