I recently bought a used 2016 Sierra Denali 5.3L 4x4 in March with 48k miles. Truck has been great until yesterday (now 52k miles) when I ease into the gas it shudders and shakes like crazy until i punch it. The tach is bouncing up and down and it doesn't matter if it's in v8 or v4. It almost feels like it's a misfire but it's weird that it only does it when I'm easing into the throttle or going uphill. The truck has the 8 speed transmission. Has anyone else ran into something like this and would the manufacturer warranty cover the fix for this?

I have the 4.3 V6 and it does the same exact thing. I know a guy with a brand new 2017 with 18k miles and it does the same as well. C'mon Chevy ! Been makin trucks for decades and you mean to tell me you can't make a truck that doesn't do things like this?

Use the search and put in "gas pedal flex solution". There is a long thread on symptoms and solutions. Easy fix.

I checked it out but unfortunately that doesn't seem to be the issue with mine.

Take it to a dealer to get it checked. You should have some power train warranty left at 52k.

Sorry I dont have the exact details right now for you because Im at work, but there is a bulletin for the transmission to be flushed 3 times and be refilled with synthetic.  Had the same symptoms (always around 14-1600 rpms) and this was a temporary fix for about 10,000 miles.  Thats my guess if you have the 8 speed.


Wow i havent been on this site in a long time.  My sig pic is waaaay outdated.  I have a 2015 Denali 6.2L now

You are experiencing the torque converter shudder, pretty common apparently, my 16 has or had it and the only fix they will do is change the fluid in the trans once and that is it for now. For me I felt like I was running over rumble strips when I lightly accelerated. Mine hasn't come back as of now. Apparently there is a more permanent fix coming first quarter 2019.

UPDATE: took it to the dealer and they said it is a pretty common issue with the type of ATF fluid that GM used in these trucks causing the torque converter to shudder. They changed the transmission fluid and it seems to have fixed the problem.

I actually have the same issue. Always and only when either accelerating LIGHTLY or going uphill with low power. As soon as I gun it and it it winds up to higher gears it goes away. Has never happened while not accelerating so I know it's not my 22s being unbalanced or anything like that.

 

And it actually comes and goes. Some days I don't notice it. Other days it shudders and the steering wheel shakes like I'm driving over rumble strips while trying to drive lightly (driving slower to conserve MPG)

Dropped mine at the GMC dealers.

They flushed the Transmission and the Torque converter.  

Replaced fluid with Mobile 1  ATF Transmission fluid. 

The shuttering went away and truck now drives perfect.

Just want to check back in. I did the same thing with my truck. It now drives like new again. Make sure you tell the tech you believe it may be TCC -- the service rep tried to write it up as a steering issue becuase i mentioned that the wheel shakes like rumble strips when it happens.

 

The dealer definitely knew about the issue, but didn't verbally address it directly with me. He breezed over it "we've been having some tranny hiccups..." 

 

Make sure they follow the bulletin and hopefully others with this issue will have it resolved.

Hey guys I got the same problem with my 2016 1/2 ton Chevy LTZ with almost 60.000 miles on her.But I had the problem with the transmission shifting from 1st to 2nd and I was thinking it was the 6.2 tight,wrongful thinking.But later on it got to shuddering bad.Took it in they changed the transmission fluid .Did good for a while then the shudder can back.It only does it when it wants to.Took it to the dealer they said if it is not doing it when they test drive it,they can not do anything for me.So today I drove it 45 miles and it did it the hold time .And this is the 8 speed transmission,and I’m am told at the dealership that some of the 10 speed does it too.So I,m in NC and I file a complaint with bbb and let’s see what gm will do.They need to replace my truck or buy me out,had enough.

I'm experiencing the same issue with my new (used) 2015 Silverado. I'm going to go get the transmission flushed and replaced with the synth; HOWEVER, my question is this: is there any way to get this covered under warranty???

      My 2015 1500 LTZ Silverado suddenly won't go into 4 x 4 low. It will go into 4 x 4 high.

      Transmission Woes :-(

      By asilverblazer · Posted

      Yep, just a quick reference point.    My main point being I’d do a thousand other things before I’d pay 10k for a transmission.    Speaking in ignorance cause I don’t look at these trucks, what is it worth? 20k?

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      I think users are going to want to pick their monitored parameters, which parameters they want to see first.    It should probably start with baseline at a minimum and adjust to learned, but be able to overlay baseline for comparison.   A simple severity level would be able to determine what type of alerting is appropriate or user selectable.    Why not use the OBD port though?   I think a phone connection would be a good idea, push notifications type deal.   Number 1 issue is having data is useless if you don’t know what the data should be under normal conditions.

      summer road trips in the 2026 2500HD

      I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that.

      Ac not keeping up

      By Aimatdeer · Posted

      Monday looks like a good day for the dealer to test an ac issue. Hopefully it all turns out good.
