  1. It was 32 or 33 when I started. I'm located in British Columbia, but have family in Wisconsin. I was last in GB and visited Lambeau in the 2019 off-season.
  2. Update from me.... truck hasn't moved in 24 hours. it was 36F this afternoon and I knew I had to go out this evening, so I plugged the truck in to see what would happen. Truck plugged in three hours, coolant temp is 73F on startup. No engine fans!! Truck built January 2020, latest ECM calibration installed late May 2020 when I purchased. No idea if GM has actually made a fix for the engine fans in the software or if it's just coincidence, but I'm happy. ?
  3. Interesting. Seems rather short-sighted to eliminate the thermostat when GM knows there will be problems plugging in above 0F/-18C. I wonder if you could just get a block heater cord with the thermostat and let that take the guess work out?
  4. I didn't mean to mislead anyone. The Techlink article itself said "available shortly" back in 2019. We're now 14 months past that article and most people would agree that is well beyond "available shortly". This is my sixth GM vehicle with a thermostat in the block heater cord and none of them had an issue with fans coming on when plugged in at too warm of a temperature. If the software engineers can't fix that in 14 months, maybe they should hire new ones.
  5. "If this condition is found, clear the DTC and return the vehicle to the customer. Do not perform any further diagnosis or replace any related components. An updated calibration will be available shortly." That was December 2019.
  6. I'm curious to hear what you find out. My truck was built in January 2020 and not sure if I have the latest ECM programming the Techlink article mentions. Thanks for digging!
  7. I have a Sierra AT4 with the 3.0L Duramax and it is also stamped 9.76 on the rear diff.
  8. This truck is a 2020 with less than 150 miles. I just haven't updated my profile yet. ?
  9. It's a warranty claim, and it's the GM dealer who wants to use the Ford fluid. I will make sure they document that Mercon fluid was added in case anything happens down the road. I have 6 year bumper to bumper.
  10. My 10 speed had an o-ring fail and needs transmission fluid. The GM dealer has no Dexron ULV, but the Ford dealer across the street has Mercon ULV. Are they the same fluid? Both fluids recommended for each respective 10 speed.
  11. Thank you! That seems quick considering the front half shafts get replaced.
  12. Does anyone know the labor time to install this kit? On the accessories website, it recommends to have installed by your dealer. Thanks! https://accessories.chevrolet.com/product/lift-suspension-upgrade-system-for-4wd-vehicles-84768243?year=2020&make=Chevrolet&model=Silverado 1500&modelId=491&body=Extended Cab Pickup&bodyId=18&wheel=Standard Box&wheelId=651&trim=LT&trimId=430&drive=4WD&driveId=8&engine=3.0L L6 DIESEL&engineId=17881&bodyNumDoors=5&categoryId=98004
  13. I have a 2015 5.3L Sierra. On a warm start (truck shut down for an hour or so), the RPM's will often start around 1100, then briefly rise to 1400 before slowing dropping to normal idle speed. Everyone else the same or should I take it in? Thanks!
  14. Bought an Airaid intake, now I just need to install it. Thanks for all the "welcome" replies everyone!
