I went to the website and read the instructions. Is it really that easy and straight forward? I can do this in my driveway? Thanks newdude. I have read...countless numbers of your posts, all helpful. I appreciate what you put into this forum.
I have a 2018 with the 6.2l and 8 speed. I had the shudder issue pretty bad. Mine was mostly the "rumble strip" experience. If I was driving at a steady speed the transmission would "load" like it was going to shift up, then never shift, which would cause the truck to feel as if it was driving over a rumble strip. It did this every minute or so. It was terribly worse when towing. Would make the truck shake pretty good. I had the service done with 22621 on the odo on Jan 21 2020 and it worked like a champ. I have ZERO issues now. It was covered under warranty, so I paid $0 for this to be done. 100% worth it in my opinion.
I would check craigslist and get a feel for what people have OEM's up for. Here in Jacksonville, FL prices are all over the place. If you have a number set in mind, be prepared to hold onto them for a while. For this one I honestly don't know if he is selling one, or the set of 4. https://gainesville.craigslist.org/wto/d/gainesville-22-chevy-silverado-wheels/6753311470.html This set isn't 22", but its a 20" Denali HD wheel. Going for 1500. https://ocala.craigslist.org/wto/d/leesburg-2018-gmc-denali-wheels-and/6741357144.html Sort of comparing apples to oranges. Check around and see what the market is.
I don't have one on my GMC, but I had a Volant on a Nissan Frontier 4.0 V6 that I used to have. It made the V6 scream. Really opens up the airway. I paired it with an intake manifold spacer and it really made the engine sound better, even with a stock exhaust system.
I just bought a 2018 Denali and tried this to see what would happen. I pressed and held the power button and got the screen pictured. Only the outside temp and time was displayed on the screen. I turned the truck off, then after work turned it on and the same screen was on. I put the truck in reverse and the backup cam still works, but no radio sounds at all.
lol. Happens to the best of us.
