Mine has been to the dealership four times with a shudder. (3 different dealers)   They say it's normal.  This is my last GM product. I can't stand driving my new truck

Take it to the dealer again and tell them there is a TSB 19-NA-121 out for TCC shutter this as it flushes and changes the trans fluid to the new type of Mobile 1 blue label fluid, I had this done about a year ago and all is fine.

@nichos I think I’ve been having the same problem on my 2019 Silverado 1500 5.3L V8- getting worse/more frequent the last month or two.
 

Did you get the Trans fluid flush done and have any benefit? 
 

Hoping I can get away with just the TSB that @Silverado4x4 mentions there.

 

thanks in advance!

@Garystruder I think it did for a while but the problem came back. I took it in at the start of the year since I knew my 60k powertrain was expiring. The dealer said it would be covered and GM would rebuild it for free.

 

I was fortunate though, the dealer included a 100k warranty when I bought the truck and I was able to get a new transmission (see this thread: https://www.gm-trucks.com/forums/topic/263709-2020-chevrolet-silverado-1500-8-speed-shudder/#comment-2647696 )

 

Anyway, I have the new transmission, I wouldn't say it's smooth, but the shudder is definitely gone. Still had shift when she's cold.

 

Good luck!

I experience the same thing a high frequency vibration. It’s not at a severe level yet I was concerned. I took my truck into the local Chevy garage. The service manager said it was due the torque converter. He wanted to replace the fluid in the transmission. He said that might help. $675 later with new fluid the high frequency vibration comes and goes as before. 
I’m planning a 2,000+ mile trip over Christmas. I’m concerned regarding possible transmission failure on the trip. The truck is a 4 door with a 5.3 liter engine - 4x4 of course. The truck has 130,000 plus miles on it.

Same deal.  2019 with 5.3L at 44k miles and started to experience a slight shudder at about 25mph with gradual acceleration.  I use a Range device to disable DFM.  Brought it in and had the Tranny flush....seems to have made a difference.  Do not have any symptoms afterwards and keeping fingers crossed.   Dealership was quick to point out either the Tech Bulletin for Tranny Flush or TC issue.

I have been having this problem for the longest time! I have had several dials ran on it and nothing. Came across this thread and it looks like there is a TSB?! I thought GM service centers were supposed to check these when you bring your truck in for service?! I’m shocked at this discovery. I could have some serious damage happening to my truck and GM has failed to send me ANY letter of any sort stating there is a TSB! GM, please reach out to me to help come to an amicable resolution for both of us. I love my truck, 2019 Silverado Z71 RST, affectionately named “A10 Warthog”.

Just brought my truck in to another service shop. Shudder is so bad…they recommend an entire transmission swap!!! How on earth can that be?! GM…if you’re reading this, would love to hear how we can work together to resolve this without lawyers.

    • Monthly payment is only part of the equation. With today's prices and interest rates, I'd look at the total monthly cost: payment, insurance, registration, fuel, maintenance, and expected repairs. A vehicle that fits comfortably into your budget is usually the better choice than stretching for a higher trim. I've also kept my vehicles longer over the past few years. New cars have gotten expensive enough that driving one for 10+ years, while staying on top of maintenance, often ends up being the most cost-effective approach.
    • 10 Ford and Chevy engines proven to reach 300,000 miles   You may note a common 3K OCI on this list of gas motors. I skipped over the diesels. Dh'O. 
    • Thanks newdude!  By the time manual selection is needed, I'm probably too much of a control-freak to depend on the transmission sensing braking to activate automatic downshifting.  I would be anticipating the situation and already be manually downshifting.   This truck replaced a 2004.5 LLY diesel with the Allison 5-speed.  Putting it in T/H made noticeable differences (when the torque converter locked, upshift points, downshift behavior).  On this 2024 gasser with the 10L1000 I haven't been able to detect much, if any, difference.  Ok, I can never tell now when the torque converter locks up.  But I also don't notice differences in shifting.  For downhills, I've probably already manually downshifted by then anyway.  Since it's also more awkward (than the 2004.5) to engage/disengage I don't even bother.  Or maybe it doesn't really matter with just a 3k lb. camper in the bed?   Thanks also for the list of reasons the charging system might select various voltages.  However, what I am seeing doesn't fall into any of those categories.  It very definitely, and very consistently, rises after coasting/braking.  Maybe not immediately, but not very long after coasting/braking.  Very consistently drops voltage when no longer coasting/braking.  It might also be interacting with the camper battery charging (I might disconnect the camper and see if it changes the charging behavior).  I also need to recheck turning on headlights for when I want to force it to charge the camper.   Another JR, in June I converted the camper to LiFePO4.  Since it's not a good idea to try to charge lithiums directly using truck, I installed a Victron Orion XS DC-DC charger (which BTW is AMAZING!!).  Being cheap, I only had to buy that one item (besides the battery, of course) to do the conversion.  The camper OEM 120v battery charger (only 19 years old and works perfectly) and the truck feed the input to the DC-DC charger (not at the same time).  But I didn't want the camper charger feeding back to the truck so I kept the old separator.  I considered replacing the separator with a 30amp diode but that means more work and might add another 1/2 volt drop.  One thing that surprised me was the voltage drop over the long 10awg wire run, so I can only charge smoothly at 8 amps (because the DC-DC charger is completely configurable).  Another reason I don't want an added voltage drop with the diode.  I might also be a little lazy but all this work is being done under the sink with a small cabinet opening.    
    • apparently CA smog is (or at least was)  checking that the vehicle is using the oem and/or a ca smog approved tune, so I expect you'll fail inspection doing it.
    • yes, leaking exhaust will mess up o2 sensor readings, which in turn messes up fuel trims.
