(P/N 23469809 – Qty 2) Note free under warranty read bulletin

 

Also you can read the Bulletin Helps understand where GM thinks the issues are. There are other bulletins for trans,converter, program(8speed) and also a rear shock recall.

Should apply for 17 also. It was just dated at the time for those years. Same body truck. Honestly print the bulletin and walk it in. They like to act like you the customer doesn't know. But parts are free and so is service so screw them make them fix it. Also depending on your issue there is a bulletin for undercoating spray above trans.

Yes as I stated there are other ways to fix depending on truck options and trims. The worst seems to be the 8speeds. Also the 2 degree can be too much. Then there is a bulletin for that, so I got that part coming also. 72190e5e1ca0509200f1238c8116d3b7.jpge17cf6260d4b152a5887a7f08256bbc8.jpg18aa24f8e3e7cb8e6e4ffb525d419753.jpg

787 pages of Shake and Vibration issues.

I traded off my 2 2014's and bought a Raptor and King Ranch back in April.

How often have they been in the shop for Warranty? NEVER

 

Chevy man for over 50 years but the new Government Motors is crap.

Yup....got sick of the shitty 8 speed,highway vibes,and multiple lifter n pushrod failures....dumped the POS and went back to Ford.

When a dealership shop admits the tranny wasn't right but Chev wouldn't touch it was the final straw....

GM can kiss my ass

Lots of folks believe the  pushrod/cam in block engine  is obsolete technology as compared to the DOHC engine.  Actually, both designs date back to the turn of the 20th century.  And, there are pros and cons for each.  The pros for the pushrod is it’s lighter (exempting the true hemi elephant) and has a lower center of gravity, generally creates more torque (push) due to a slower burn rate.  Pros for dohc is faster burn rate, more high rpm hp, no valve float to speak of, great for racing.  So, the debate about which concept is better depends on usage and preference.  Personally, for truck use I prefer the naturally aspirated pushroad.  Just my two bits 😊...

Smooth as glass....the ride and the tranny.

Hope the GM 10  speed is as good

I think the development of 10 spd tranny was a joint Ford/GM collaborative endeavor.  So, presumably it should function about the same for both.  Perhaps, some programming differences such as shift points, etc.  just guessing though...

So traded my '14 double cab. Decided to stick it out with GM and got an '18 Silverado Crew Cab regular bed. So the 153 wheelbase. 5.3 Z71 6 speed 3.42... Well it doesn't vibe much on the highway but a bit of a shudder on acceleration and deceleration. Having played the shim game on my last truck,  I rolled my eyes and looked underneath. I guess they are rolling them out with shims in them now. I was perfectly smooth till the 500 mile mark. I don't highway much. Prolly have them taken out. Funny part is, in Maine, when you buy a new Chevy, you get lemon law paperwork with your packet and owners manual. Once it's your fault. Twice it's mine...

They come with shims? Can you expand....

There are shims in between the leaf springs to change the angle between the drive shaft and rear axle assembly.

Ohhh.... I guess I missed a few pages.

Is that affected when guys level / lift trucks?

Obviously the shake is there from the factory on some of these trucks (my 2014 included) so ...

      I am a proud owner of a GMC Yukon 2016 Denali. Since these cars are not officially available in Europe, I imported a Yukon. Basically, I am very satisfied with the vehicle.
       
      But unfortunately, I have a problem with the vehicle, and nobody could help me so far: The car vibrates quite heavily and uncomfortably. The vibrations started when I stopped at the side of the road to let my wife get out. The engine lamp flashed, and the vehicle had hardly any power left. I drove about 1/4 mile, stopped again, and switched off the car. Afterward, I waited for over one minute and then restarted the car. The engine light stayed off, and so I was able to drive on. Also, the power was as usual again. But from there on I had vibrations which I didn't have before.
       
      So I went to a service station to read out any errors and get some help. But there were no errors detected. Since the vibrations did not disappear on the next miles, I went to the dealer again. They reprogrammed the ECU unit with the latest software and balanced the tires. Nothing has changed. So I went to another dealer, hoping that it could help me in a better way. They told me that my tires were worn out and that they could cause the vibrations. We changed all four tires. The handling was a bit better afterward, but the vibrations remained.
       
      Because in my country there are just about 10 GMC Yukon and a few Escalades driving around, no dealer has a clue and can solve my problem. Therefore I did a lot of research on the internet and on the paid platform of GM (ACDelco TDS) - unfortunately without success so far. 
       
      I am also familiar with the service bulletins for the 8-speed automatic transmission. But I can exclude these vibrations so far. I have some of these vibrations in my car. However, I have now imported the right oil from Texas by ship, and I will do the oil change within the next days.
       
      But the other vibrations are noticeable at any speed, even at only 1 or 2 mph or over 100 mph. Especially when I ride uphill or downhill, it vibrates a lot. As if I had no suspension in the back and the vehicle would bounce around. The vibrations are mainly felt in the seat. Very slightly also in the steering wheel. From the beginning, my car tends to steer slightly to the left. But I never paid much attention to this, because measuring the track showed that everything is ok.
       
      I am aware that a remote diagnosis is challenging. But perhaps you have any ideas where I should proceed with my further diagnosis? Is the suspension the right start, the drive shaft, or the wheel mounting? Or could it be the engine mounting? Or something completely different? What is the best way to proceed?

      Patient - 2019 1500 LD, 5.3, 6 sp, 7200 miles old, Covid-19 negative.  Symptoms - 2-3 second shutter / shake / rumble, during light acceleration, 30-40 MPH and low RPM.  Happens while both in V4 mode and while in v8 (manual w/ transmission set to L5).  I thinks its the torque converter, but surfing the forum I see this issue mainly referenced to 2015+/- K2s and I'm not sure if they changed the trans in the final years.  I'd appreciate either a TSB # or a link to another posting were I could find the TSB.  I'd like to be able to take to my dealer and say "HERE....READ....FIX" (politely).  Many thanks!

      Hi everyone, new to the forum but I’m at the end of my ropes here this is my Hail Mary. So I have a 2016 Silverado crew cab 6.5’ bed 5.3l 4WD 6 speed automatic transmission. The transmission was fully rebuilt at 75,000 The truck has 89,000 miles on it. I am complaining about a shake/vibration of course but I don’t feel as if mine is like most. Mine doesn’t seem as violent as others describe. I’m experiencing a vibration and a noise almost like driving over rumble strip in the road. This problem comes about when you are gentle on the throttle and at a lower rpm around 1200-1500. If you feather the throttle at 55 MPH you can easily replicate the issue. Next is issue number 2 I’m not sure if they are related but my gut is telling me they are, I recently noticed when stopped then slowly take off as in just letting the truck roll at idle of the line I feel like a small wobble/bounce as it kind of rocks you back and forth in your seat. Both issues go away once you give it more throttle. I’ve had the torque converter replaced first once the issue came back I then I’ve  changed the transmission fluid to the updated fluid, rotated the driveshaft 180 degrees and that has been the longest fix for 3 weeks. Any suggestions are helpful and appreciated and thanks in advance

      This truck is my first 4WD/4x4.  So a few weeks ago, I put my truck in 4HI, to drive in the snow, no issues.  Put it back into 2WD, when I got home, and haven't needed it since, until this afternoon.  When I put it in 4HI, it was grind/vibration central, but when I put it back in 4AUTO or 2WD, there is no issues.
