Good to know. Like I said, they replaced with a new one (so they say) and it still happens. But it’s still only for like a quick second. That’s the least of my worries. Sent from my iPhone using Tapatalk
Any one know why the U bolts are coming torqued 50% less than factory says they should be?? Makes no sense. I posted a video several pages back of the water bottle shaking in the center console. Took to the dealership and they ran the pico scope on the steering wheel and driving up to 78 mph (they say) and it was all in range. Couple spikes up to 20 that they attributed to the road, but all what GM believes is acceptable. They’re not smooth in southeast Michigan). My truck is bad in the 78-83ish range. And i only have 13k miles on the ‘16. 90 mph is completely smooth. Just came back from Green Bay this weekend (1000 miles total) and the shake was bad even on smooth asphalt roads with no grooved pavements. So much so that just by having your arm resting up on it and you take a pic, it’s blurry. So a lot of people suggest after market shocks and tighten U bolts? Sent from my iPhone using Tapatalk
Have an appointment Monday morning and the service manager wants to go for a test drive (of course). Hopefully the significant shake will be enough to warrant a new trans flush, and Murphy's law doesn't go into effect. Fingers crossed! Will let yall know what they say. I have few things they need to work on. Oil change, hopefully a trans reflash for the shifting issue, vibration issue, and now a rough noise when ignition turns from a cold start. Yay -_____-
I have a 6 speed and it still happens when I have my afm disabler in. Shifting is a little better too. Its a toss up for me for which i rather have an issue with over the other. haha. I'd like both to be fixed since its a $45k truck. Not normal!!
Yeah I thought about that. Just seems hit or miss on here. Some people don't have the issues, and/or shake, other have it. When I first bought the truck and maybe up to about 5k miles I didn't notice it. But now its very noticeable. And its not just the center, you can feel the vibration all over. I can hear the zippers on my bag rattle in the backseat too. It's just these $45k trucks shouldn't have these "normal" issues.
Dmf10e replied to ct_corey's topic in 2014-2018 Silverado & Sierra TroubleshootingI have a 2016 silverado double cab 4x4 v6 that has the same shake as yours at highway speeds. I posted my video going 75 mph. So annoying and very unacceptable. I have yet to take it in, but on another thread here they refer to the TSB Bulletin 16-NA-175 that seems to fix a lot of the shake issues. I will be trying to get that done hopefully in the next month or so when I get my oil change. IMG_0511.MOV TSB Link: https://www.revbase.com/BBBMotor/TSb/DownloadPdf?id=201234
The first video, I'm idling (Slight vibration). The second is going down the interstate at 75 mph (Being agitated considerably). I heard the TSB #16-NA-175 addresses this issue, but i have a V6, which isnt listed on the bulletin but its the same transmission. Hopefully the dealer still will cover doing this bulletin. Regardless it's not normal! IMG_0506.MOV IMG_0511.MOV
I agree. Supposedly it's normal, including the words from the dealer. I have a 4.3 6 speed, but will wait until the warranty ends before I tune. As far as the shim, can you post a pic of where to put the shim? Tried to look the other day, but couldn't figure out where to place it.
Is this something that works for a 6 speed as well? I understand I'm in an 8 speed forum but I'm having the same issues. Would the fluid be the same? And the dealer wouldn't have a problem putting this fluid in? I own a 2016 Silverado v6 6 speed.
