    2018 Sierra SLT Crew Cab
  1. I was hoping someone could tell me the torque spec for the rear diff cover (9.5”) and transmission pan bolts (8 speed). Thanks!
  2. Transfer Case Fluid

    I am looking for the GM part number. Thanks for the reply though!
  3. Hi, I am looking for the right transfer case fluid for my Sierra with “auto” selection (if that matters). I know it needs Dexron VI, but I see a synthetic and what may be non synthetic. I was told it is part number 88865601, having a hard time confirming. That appears to be the one that does not say synthetic on it. Thanks in advance for any help.
  4. Main reason I ask is I feel mine was louder tonight when I got home. Anyone notice varying noises? The buzz was louder tonight, was also after fairly hard driving in traffic.
  5. Any other ideas? If this is like mine, it is inside the transmission and isn’t evap system. Lasts about 20 seconds, you hear a solenoid click and then it stops.
  6. 2015 8 speed transmission noise

    Digging up an old thread... Has anyone identified what in the transmission is making this noise? I heard mine tonight and it was a bit louder than I have hear before. I assume it is some sort of circulation or purge pump, but would really like to know. You can hear the solenoid click off after about 20 seconds.
  7. Guys, I’ve been hearing what I thought was an exhaust leak on the driver side of my truck. Turns out the manifold to converter bolts were loose. I was able to get a little bit of a turn but not a whole lot. I snug them up for now but I was hoping to find the torque specs for them and also understand the seal type. If it is a metal seal I feel better about retorquing and moving on. If it is not a metal seal I will likely replace it. I am hoping it is just a relaxed seal after some heat cycles and miles on the truck. Not trying to go to the dealership for a $10 part under warranty.
  8. I have been getting annoyed with my auto light setting. If I go through a shady spot the interior lights dim and outside lights come on. The biggest pain is the inside lights. It is sunny, so I have my sunglasses on and can barely see. I end up having to constantly adjust the level with the dial. Every other vehicle I have you can adjust the auto sensitivity, but I am struggling to find it in the truck. Is it adjustable?
  9. TCM Location 2018 A8 Sierra?

    Thanks, not sure how I couldn’t find that searching though lol
  10. TCM Location 2018 A8 Sierra?

    Do you have a link to that? I don’t see it anywhere. I thought they only modified one you sent in.
  11. TCM Location 2018 A8 Sierra?

  12. TCM Location 2018 A8 Sierra?

    Awesome, thanks! I like that answer, not looking to tear into this thing that much lol
  13. TCM Location 2018 A8 Sierra?

    Darn. Any info on how to get it out?
  14. I have not had much luck confirming the location of the 8 speed TCM for the 2018 Sierra. Does anyone have any descriptions or pictures? I have seen a few older threads stating it may be in the transmission, hoping wherever it is access ins't a pain. Thanks.
  15. Lower Door Sill Protection?

    Thanks guys. I have put on door edge films and bumper appliques so I feel good about the install. Looks like I will order some standard stuff and put it on.
