My wife's 17 Yukon Denali was experiencing some shutter last week while we were on vacation in the mountains. Seems to do it at around 30-35 mph. The truck has 21,000 miles and the 6.2/8 spd combo. I haven't taken it in to the dealer yet but I plan to. My 16 8 speed got traded at less than 8,000 miles due to this issue. I also have a 17 Sierra AT with the 6.2 and 8 speed. I would be lying if I said GM has me a concerned. At this point if they haven't found a decent resolution for the 8 speed they are not likey to, and since GM is abandoning the trans for the 10 spd why no option to upgrade to the 10 spd rather than so many shop visits? I don't see me buying more GM vehicles in the future. Pretty lousy for all that have had issues and continue to wait for a resolution. Trying to do a lemon law case is not fun, as I had a 13 Tahoe that went to the shop on a wrecker 6 times before it was 6 months old. GM did nothing but my dealer helped considerably.

I didn't mean to set you all off. I live in SW GA and every other truck locally has a Ranchhand front and rear bumper(seemingly). To the point of needs, I will just say that if you need a bumper because you hit things, maybe just don't hit things, haha. I have yet to run into anything in 25 years of driving. Some of the bumpers look great, but the Ranchhands mostly look homemade. Sent via Morse code

I don't get why get thinks that they need all these parts to gain 2". Seems like a huge waste. Anything with a Z71 on it should have that(offroad...). I would think that a name like trail boss would mean it was trail capable but I don't see that as the case. Sure they will go down a trail but no one buys a new GM because of the trail capability. Sad really. Sent via Morse code

I don't get the aftermarket bumper craze. They mostly look like something someone created in a barn, not to discount the talent that it takes to make them. I will keep my stock bumper and pass on the grille guard. Sent via Morse code

I will likey swap to 5w20 next time on my two 6.2 vehicles. 0w20 in the deep South is likely on the thin side. If 5w oil burns up an oil pump it was probably weak anyway. Sent via Morse code

Oh I thought that they had rectified the issues. Sad. Sad. Sent via Morse code

I am curious as to why they don't just swap out the 8 speed transmissions that are causing problems with the new 8 speeds. Seems like it would be cheaper for them in the long run. My 8 speed in my 16 was a joke and I traded it at 7500 miles but wasn't sure what was wrong until reading here. Dumb me I bought another 6.2 with 8 speed. I haven't had any trouble with it but I only have 4500 miles or so. My wife's 17 Yukon Denali has the 8 speed also and 20,000 miles but all seems ok. Sent via Morse code

Why the proclip cell phone holder when the truck has wireless charging and navigation. Just curious. Sent via Morse code

I would guess that you will be in trouble. I couldn't run a 295 on my 2017 with snowflakes and SS arms. I wish you the best of luck sir. Sent via Morse code

I live in GA. We take truck ownership seriously down here. Sent via Morse code
