ws6firebirdta00 started following TCM Location 2018 A8 Sierra?, Torque specs - rear diff cover and transmission pan, Transfer Case Fluid and and 4 others
ws6firebirdta00 posted a topic in 2014-2019 Engine, Driveline, & ExhaustI was hoping someone could tell me the torque spec for the rear diff cover (9.5”) and transmission pan bolts (8 speed). Thanks!
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.
ws6firebirdta00 replied to Sharp780's topic in 2014 - 2018 Chevy Silverado & GMC SierraMain 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.
ws6firebirdta00 replied to Sharp780's topic in 2014 - 2018 Chevy Silverado & GMC SierraAny 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.
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.
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.
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?
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.
