I got lucky so far. March 2018 production date. Vehicle is kept outside and I do keep up with washing polishing etc. Still hanging in there. Fingers crosssed.

Wondering if all the time limits are out the window now because we are not in “normal” times. Pandemic/chip shortage. Also could the owner locate one himself say at a salvage yard and have it installed until a new part is available? At he would have his truck. But then again it’s probably costly. Heck what’s not these days. Sent from my iPhone using Tapatalk

The new update on my iPhone is crap. Constant crashes and logs out. I have deleted and installed. No luck. I’m going to call onstar and complain. Maybe I can get a few free months. Sent from my iPhone using Tapatalk

Did you just acquire the vehicle? Did you buy it new? If so did the shake just happen now? Sent from my iPhone using Tapatalk

That would be unknown. Are they still building with those lifters if the engine can’t perform cylinder deactivation? Sent from my iPhone using Tapatalk

Agreed. I just read some 2021’s are being built without afm due to parts shortage. Some lucky ones will scoop these up https://finance.yahoo.com/amphtml/news/gm-builds-2021-pickups-without-134828278.html Sent from my iPhone using Tapatalk

He turns the AFM system off so it’s full time V8. That has nothing to do with emissions. Sent from my iPhone using Tapatalk

Might be worth checking out. Free replacement if affected. https://static.nhtsa.gov/odi/rcl/2021/RMISC-21T001-5089.pdf Sent from my iPhone using Tapatalk

I have been using these filters and never had an issue. I always inspect before I install but anything mass produced will have defects. I’m also wondering if the gasket was stuck on the block from the previous filter and the tech didn’t realize it. I have seen them leak when that happens. Just a thought.

I also have a Lew tune. Nothing but a positive interaction with him. His communication is great and quick with replies. Very satisfied with tune. http://diablewtune.com/ Sent from my iPhone using Tapatalk

It’s the antenna amplifier located behind rear seat on passenger side above window. I chose to do it myself even though I am still under warranty. About 25 bucks from rockauto and 30 min of my time. I just didn’t feel like finding greasy fingerprints on my headliner Sent from my iPhone using Tapatalk

Had my 6L80 tuned when I went with a 93 tune from Diablew. My shifts are firm going up but no jerking on the downshifts. I used to have the same problem as others with the factory tune. It was annoying. I changed out factory fill at 24k miles to AMSOIL sig trans fluid. Now have 34k miles and no issues at all. Fluid still cherry red. Sent from my iPhone using Tapatalk

Had my Tahoe engine oil cooler lines replaced last month and they were covered under powertrain. The transmission oil cooler lines are not. Sent from my iPhone using Tapatalk
