2017Darkness

If the cam lobe is wiped, it will usually make a high pitch squeal at idle. It's very quiet, but it will have an intermittent squeak or squeal when that lifter contacts the cam it the right spot.

If they would retest these vehicle with 10 or 15,000 miles on them it would be a different story. I've had a few 5.3's over the years and currently have a 6.2 that, even with 35's and a 4 inch lift, would dust any of the 5.3's I owned before by way more than a half a second. Not trying to argue, just speaking from experience.

I have only seen one 2018 that is included in this recall....Most are prior to 2018 model year. If your VIN is not on the list, it probably will not be added.

We have had one come in with this issue so far. Had to add some dumdum between the roof and spoiler bolts. Customer is very, very particular about his truck and have not heard back from him on the sound in over a month.

It is a "if you have a problem" fix, or special coverage if the issue occurs to your vehicle. Your signature shows a 2018, so you wouldn't be covered....

Is that the GM cold air intake that the dealer is supposed to update software when installed??

DAMMIT, now I might have to trade...

Have any of you tried a funnel like this? https://www.amazon.com/Assenmacher-Specialty-Tools-OFGMRD08-Engine/dp/B00JLZ9FDI/ref=pd_lpo_vtph_263_tr_t_2?_encoding=UTF8&psc=1&refRID=S6XAKKHMTJ5TDCRK1P2P it threads into the filler tube...most of my techs use it

Battery....It's got a bad cell. We see it all the time, a customer will hop in and drive to the store and it won't re-fire. Sometimes that cell will have a charge, sometimes it won't.

I did my fair share of car stereo installs back in the day, some competition, some sound quality, but I would be completely lost today...The technology has come a loooong way. Awesome setup

So you want the effort to be the same at 45 as it is at 70? There should be more effort at higher speed when you get outside of normal lane change maneuvers because you should have to overcome the system if want to make more than 5 degrees of steering at 70mph. Maybe I'm mistaken what you looking for.

Not true...Most occur early in life, usually while still under warranty.

They don't share that secret with us. It may be the manufacturing tolerances, it may be the compound mix in the converter clutch that day...do not have an answer for why.

You KNOW this won't fix the shudder issue?? I write service for and Chevy dealer and can assure you the flush takes care of 98% of the vibration issue. I had my 17 6.2 flushed in early December and have put 4,000 miles on it and the issue is gone. The dealer does not start with any procedures other than driving the truck with a PICO scope, no balancing tires, no measurements, none if that stuff. The issue is not the torque converter, it is the electronically controlled clutch actuating at a high rate and slipping because of the fluid. The only vehicles with this issue that were ever supposed to get converters replaced were 8-speed Colorados. GM allowed some dealers to replace the converters in some trucks, SUVs, Camaros and Corvettes because they were chasing there tail trying to find a fix. There is a new repair procedure out where even the Colorados do not get converter replacement. There is a new fluid from Mobil that is shipping out to the dealers and is expected in towards the end of this month or middle of next. There are some dealers who do have been doing the procedure wrong and that's where people get the idea of it being an ongoing issue. And this issue effects maybe 10% of GM vehicles with the 8-speed, it's not the epidemic people make it out to be.
