Amazing how 2 different dealers can come up 2 completely different diagnoses. I will definitely reference your fix when completed and show my service dept. this fix. Thanks

Got my truck back today and referenced your video, the mechanic and shop lead person said it was normal, but noted it on my paperwork. Anxiously waiting what your local dealer is going to tell you lonewanderer812.

I have a 2022 Sierra SLT Texas Edition 4x4 with 5.3 and 10sp tranny doing the exact same thing. It’s currently at my dealer being diagnosed for that an a oil leak. Been there for several days and no info as of yet.
