I have a 23 Silverado, 12000 miles, with the 3.0 doing the same thing so mine cannot be AFM.  I get a slight vibration or shutter when maintaining speed at around 1700-2000 rpm.  Do you remember back when you drove a clutch and you shift too early and it would bog and shutter until the rpms got up, that is what I feel. Seems like torque converter shutter.  I took it to my local Chevy dealer and they said they cannot replicate it.  I plan to take it back in and have them ride with me to help them see the error in their ways.

We regret to hear of this vibration and shutter concern in your 2023 Silverado and would like to help investigate further. Please send us an email to [email protected]. Be sure to include your Username and Forum name in the subject line with further information. We look forward to your email.

I have 2023 Sierra 1500, 5.3, 10 speed, low milage 10K, and noticed the same vibration at low speed. I thought I was a bit too picky but started to search and found very interesting posts. I also believe it's the transmission related to DFM. I had a Sierra 2021 and no such vibration problem at all! I was told by GM dealer in 2021, there was an association between GM and Toyota regarding 10-speed transmissions configuration so I guess that association was no longer effective in 2023. Pure extrapolation. I didn't search for that. The thing is; I found a video on youtube saying you can manually shift transmission speed to 1 lower speed, for example L9 if you have 10-speed transmission and it will deactivate DFM. 😲 I plan to try this out and see if the vibration will be there still. Keep you posted. 

 

I see GM is contacting people in this post. That's very appreciated. I would also like to be contacted by GM. Does anyone have any feedback about those private conversations with GM? Thanks!

My dealership said that could not replicate the issue and it bugs the hell out of me.

Usually at about 43/44 mph and just lightly on the pedel my truck starts vibrating like your chugging a standard transmission. 
I think they are hiding something 

2023 Elavation 5.3 10 speed

My 23 Silverado High Country 5.3 with 10spd does the same thing from 0-75mph.

it only has 200 miles on it!

there A service bulletin 22-NA-015

I’ve been chasing this same problem in my 2020 elevation for years now.  Valve body replaced (issue disappeared for a few thousand miles then came back), torque converter replaced (same thing issue disappeared for a few thousand miles then came back), cam shaft actuator magnet replaced (seemed to make the vibrations worse).  I’ve ran through about 8 dealers and they have got to the point of charging me a diagnostic fee as soon as I walk in the door in an attempt to keep me from coming back.  That GM social media email is pretty useless, they’ll make an appointment for you and that’s about it.  I hate to say it but I don’t think that issue will ever be fixed.  Seems like L9 makes the vibrations disappear for me as well.  It’s seems like the DFM makes the transmission shudder.

We should be given the opportunity to seek

the Aftermarket 5.3’s with their transmission recommendations!

2023 sierra slt 16000 miles having the same problem with vibration. Took it to the dealership and they keep it for a week and said GM said to try this and that and they did and still the problem hasn’t been fixed another 4 days later with them saying they are wanting for a response from GM engineers and still nothing. This is crazy with the amount you pay for vehicles these days

I hate to say it but I think you get a good truck or a bad truck with GM in the last 10 years, It's sad that GM used to be the most reliable or least for me and my family. I had a new Escalade in 2017 and it had terrible vibration dealership kept a total of 12-14 weeks from July 5 to December 12. They absolutely tore that truck to pieces 

 

-2 pico vibration analysis test
-Road forced balanced the wheels 3 times
-Replaced 8 tires
-Replaced transmission valve body
-Tranmission fluid flush
-Replaced torq converter
-Replaced ring and pinion
-Replaced drive shaft

-Replaced steering wheel mounts

-Checked all body mounts, rotors, etc

 

What got me was when the service manager called me and said the tire was moving on the rim when I was going down the road causing balance to get off. I had 2 separate cases with GM headquarters and that is an absolute joke, to say the least. They care nothing about you or the trouble you're having with your car, I ended up taking a huge hit on that truck and sold it to get out from underneath it. Hate you are going through this but good luck with your journey and hope you do get it fixed.

I am having the exact same issue as others here with low speed vibration/shudder around 1200-1500 rpm.  I also took it back to the dealer, twice in the first 10000km and, just like the others, the tech said they could not replicate the problem.  Also like the others, it’s a 2023 Sierra Elevation 5.3. I also described the issue to the tech as similar to driving a standard transmission and shifting too early, resulting in a shudder.  Considering the number of people with the exact same problem getting the exact same response, I am in agreement that they are fully aware of this issue and just not addressing it.  

Otherwise, the truck is amazing on the highway, has no issues under higher speeds, even at the same rpm, but this low speed shudder is driving me nuts to the point where I’m wondering what kind of loss I would take selling a less-than-year old truck with 11000km on it.

Hello,

my new 2023 shakes from 5-80 mph! Same deal it goes to the dealer and the same remains shaking vibrations that make it unlivable! GM fix these trucks!! There’s a Service Bulletin on the issue. I have driven several other 1500’s GMC and Chevrolet that are smooth and enjoyable!

Has anyone had any luck on this issue, I got mine back from the Dealership yesterday and they said we recognize your concerns, but the GM says it is just the way that some of the trucks ride.  We drove one 2024 Sierra Denali 2500 Ultimate that had zero issues and rode smooth as butter, and then another 2500 AT4 and it has the same issue as mine and all of yours!  Dealership said until GM tell them what to do, they have no idea what to fix or change, this is madness to me!

 

Legit told me to just drive faster, so I dont end up in the spot where the shutter or bad ride starts because as many of you state it seems to only happen in certain driving conditions.

 

Happens the most to me around 1000-1400 RPMs, and 40MPH.

This is the exact parameters on my path to work, so I get it daily and it is so annoying!

 

anyone have a solution?? :-(

    • Did have to make 1 modification because of the WeatherTech rear mud flaps and that was needing 3 longer screws than what came with the install package. 😄
    • Picked up the liners yesterday. Installed passenger side WITHOUT any modifications. All mounting holes lined up perfectly. Rain is interfering today with drivers side. Very Happy! Will add pics when finished
    • As a matter of amusement I’ll leave this conversation with this. Do you beat the government average fuel estimate? Statistics are a guide to me. Not a rule. Someone once said I have to have the last word. If true and possible may be. I’ll blame that on working in a family business.
    • That is a fair point, and I agree that trying to log “everything in the truck” would be the wrong direction.   There are a lot of modules and a lot of traffic. If the product became a full-truck datalogger, the amount of data would get huge very quickly, and most owners would never use it.   I think the first useful version would need to be narrow: - powertrain-side event evidence - selected high-value parameters - communication / voltage / reset events - pre/post event window - short report first, raw log only as backup   One distinction I should make is between active OBD/PID polling and passive bus capture. If you are polling PIDs through OBD, then yes: the more parameters you request, the lower the effective sample rate becomes, and you are adding diagnostic traffic to a vehicle that is already busy running itself. With passive CAN capture, the recorder is not asking all the modules for data. It is listening to traffic that is already on the bus. So it does not consume vehicle bus bandwidth in the same way that a scan tool polling hundreds of PIDs would. But your point still applies in a different way.   Even if passive capture does not add bus traffic, the recorder still has limits: - processing rate - storage rate - timestamp accuracy - decoder workload - event filtering - report size - user attention span   So the answer cannot be “log everything and let the user figure it out.” The product would need to store enough raw evidence to be useful, but only decode, graph, and present the important parts around the event.   A practical report should probably show: - what triggered the capture - how much pre/post data was preserved - which selected parameters changed - how those values compared to baseline - whether the same pattern happened before - whether any voltage, reset, bus-off, lost-message, or communication fault occurred - selected graphs around the event - raw data only as supporting evidence   So I agree with you. More data is not automatically better. The real product is the reduction from raw data into a useful event report.
    • That makes sense, and I agree with most of that.   I think the product would need both: 1. a default powertrain template, so it is useful out of the box; 2. user-selected priority parameters, so the owner or shop can choose what they want to see first.   Different users are going to care about different things. One owner may care about oil pressure and voltage. Another may care about misfire trend, AFM/DFM behavior, or U-codes. A shop may want communication events and repeatability first. Your baseline point is probably the most important one. Raw data is not very useful unless the report can show what normal looked like for that vehicle under similar conditions.   The way I would think about it is: - start with a basic known-good baseline - learn normal behavior for that specific vehicle over time - allow the event to be overlaid against baseline - show whether the event was a one-time spike or a repeatable pattern - provide a simple severity level, but with clear limits on what that severity means   For example, early severity could be something like: - Info: event captured, no obvious abnormal pattern - Watch: value moved outside baseline, but not repeated - Warning: repeatable abnormal pattern under similar conditions - Critical: communication loss, voltage drop, bus-off, reset, or severe repeated event   I would not want the first version to say “replace this part.” That would be overclaiming unless there is repair-confirmed data behind it. It would be more honest to say “this pattern deserves inspection.”   On the OBD port question, I think OBD absolutely has a role. OBD is probably the right place for: - DTCs - freeze frame - VIN - calibration information - normal scan-tool parameters - Mode 6 / enhanced diagnostic data if available The reason I am still looking at an ECM-side recorder is that the failure may happen before anyone connects a scan tool. If the owner plugs in a scanner after the event, the pre-event evidence may already be gone unless the ECU happened to save it. So I do not see this as “OBD versus ECM-side.” I see it more like: - ECM-side recorder: always armed, rolling buffer, event evidence - OBD/DLC companion: DTCs, freeze frame, VIN, calibration, normal scan data - phone/cloud: status, notes, upload, report generation, notifications   I agree that phone connection and push notifications would be useful. I just would not want the phone or cloud connection to be required for capture. The recorder should save the event locally even if the phone is not connected. The phone should help with event marking, download, notes, upload, alerts, and report viewing.   For a default GM V8 event report, would this list make sense? - RPM - calculated load / MAP - throttle position - vehicle speed - gear / torque converter state if available - coolant temperature - oil pressure - oil temperature if available - battery voltage - commanded AFM/DFM state if available - actual AFM/DFM state if available - misfire counters / roughness by cylinder if available - fuel trims - relevant U-codes / communication events - bus-off / lost periodic message / module reset / voltage drop events Which of those would you remove, and what would you add?
