It is more likely you are feeling cylinder deactivation than a trans problem.

This. I can’t tell you how many times I feel the “shudder” and hear the exhaust and they match with this perfectly. 2024 5.3 wt.

My 2023 2500 Silverado Diesel is sitting on a rack at my Chevy dealer for who knows how long due to a shift valve body that they can't tell me when they will ever see one. I'm outraged with GM! I see

Well it happened again.... As stated above, I dropped my truck off at the service dept. last Saturday, June 15th. I got a call Monday, June 24th that they repaired two wires that had shorts and u

Having similar issue but getting worse. Between 39-45 mph, foot off the gas a hair under 1000 rpm then into acceleration, the rear end locks up for about 1 second and will screech locked tires. This only happens when transmission fluid temp is above 150 degrees. Also rumbles and skips at times. Has happened at 63 mph before. Scares the crap out ya when you’re not expecting it. Waiting for loaner from dealership so they can fix. Fingers crossed.

Having same issues with my 2022 ZR2 with 6.2. Shudder around 35mph light throttle.  At times it feels like I’m pulling a boat anchor and then it goes normal. Has around 14K miles. Seems to be getting worse. Had it to selling dealer and two other dealers. No check engine or codes and they said couldn’t duplicate issue. They said normal and could be the DFM. I ran in L9 but can’t tell for sure if it’s makes a difference. 
 

I also mentioned a shifting driver seat track. Makes a clicking movement on turns. All three dealers couldn’t duplicate. I can’t get it to do it pushing on the seat. Read another owner who complained and the seat track was replaced. 
 

My factory bumper warrant expires beginning April. I do have an additional 12 months 12K GM certified. Since I bought it with 5K miles. Not sure if the GM certified is same as the factory 3 year 36K miles?

My 23 Denali 5.3 has the same shudder around the same speed. I'm thinking it has more to do with the DFM than the transmission. Try running it in L9 from the start. Drive it the same as you would in drive. No cylinder deactivation and no shudder. These trucks shouldn't deactivate cylinders at that low of a speed.

Have a brand new 2023 Silverado. Truck has been in the shop 7+ times with 10 check engine lights. I’m currently waiting to diagnose a P0087 code and also have developed a shudder. I’m beyond annoyed with this truck and GM. Have 30000km on the truck and I’m going to look into getting rid of it. Boo GM

Doesn't help you, but 46,000km on my '23 3.0 and zero issues so far.

So my 2023 transmission has had issues since I bought it with 6k on it. It has the same issue as described in this forum shuddering, harsh or erratic shifting and jerking. At time it not that bad at low speed but once 30-50mph it happens regularly although i can point to time at low speeds and high speeds. I have brought it to dealer twice. The first time they "checked the codes etc" and could find anything. The second time i drove it with manager and he drove and could not create it, although i also understand how to minimize it occurring. So the 3rd time brought in they "cleared the codes and could not find anything and when drove it it was fine"...... It is not fine and this weekend if final straw....I let me neighbor borrow the truck and about 30 minutes after using it I got a call and he asked me if the transmission was suppose to be "randomly shift and shaking, or did he have it in 4wd or was doing something wrong.....How can i get this resolved while still under warranty and why has there been no recall on this as there is forum on this site with same issues, and well as reddit and other locations......How can I get GMC to take responsibility and fix this issue?? Help???

Having the same problems with my 2023 GMC Sierra 1500.  The truck has only 24000 km's on it and the transmission control valve failed three weeks ago.  The dealership repaired it after two weeks then yesterday it happened again.  Check engine light came one, reduced acceleration message on the dash and no reverse.  Back in the dealership and of course no loaner truck to give me.  Paying $70K for a new truck to get peace of mind seemed like a good idea, I had a hell of a lot less problems with my 2005 Dodge Ram.

      5 Best Slide Down Gameplay Tips! 

      By lanaderay · Posted

      Are you playing Slide Down endlessly but your score is still low? Are you constantly crashing into obstacles as the game speed increases? Don't worry, this article will share 5 invaluable tips to help you master the race and impress your friends. Golden Rules 1. Look one step further. The mistake of 90% of new players is only staring at their character. The secret of experts is to look towards the top of the screen (where the slide is about to appear). This gives your brain an extra 0.5 - 1 second to process the situation and determine the direction of movement before the obstacle approaches. 2. Use gentle movements; don't swipe too hard. Slide Down is very sensitive. Moving your finger too forcefully or with excessive amplitude will cause your character to be thrown off course or crash into a wall. Practise moving your finger with small, decisive, and precise movements. 3. Don't be greedy for gold in dangerous locations. Gold coins are tempting for buying skins, but life is more important. If you see a gold coin right on the edge of a cliff or next to a spike trap, ignore it. Our goal is a High Score, and your score only increases if you survive. 4. Make the most of Power-ups. During the slide, you'll encounter items like Magnets (attract gold) or Shields (temporary invincibility). Never miss them! Especially the Shield, it's your "get out of jail free card" to help you get through those deadly fast sections. 5. Stay calm when speed peaks. When your score exceeds 500 or 1000, the game speed will be very fast. At this point, don't try to think logically; let your natural reflexes work. Take deep breaths and don't panic. Apply these 5 tips to your next game, and your leaderboard will surely improve dramatically. Good luck climbing the Slide Down leaderboard!

      Why I Recommend a Desiccant Air Dryer for Cleaner, Drier Compressed Air

      By lingyuair · Posted

      If you use compressed air regularly, one problem you cannot ignore is moisture. Water in the air line can cause rust, unstable air pressure, poor tool performance, and even damage to sensitive equipment. That is why I highly recommend using a desiccant air dryer. A desiccant air dryer is designed to remove moisture from compressed air by using drying materials such as activated alumina or molecular sieve. Compared with basic water separators, it can achieve much lower dew points, making it especially useful for applications that require dry and stable air. For workshops, painting systems, pneumatic tools, CNC machines, laser cutting equipment, and industrial production lines, a desiccant air dryer can make a big difference. It helps protect equipment, improve air quality, reduce maintenance costs, and extend the service life of the whole compressed air system. Another advantage is reliability. Many desiccant air dryers are built for continuous operation and can maintain stable drying performance even in demanding environments. For users who care about long-term efficiency and equipment protection, this is a smart investment. When choosing a desiccant air dryer, I suggest paying attention to air flow capacity, working pressure, dew point performance, regeneration method, and maintenance requirements. A good model should match your compressor system and actual air consumption. Overall, if moisture is causing problems in your compressed air system, a desiccant air dryer is definitely worth considering. It is practical, efficient, and highly useful for anyone who needs clean, dry, and reliable compressed air.

      I went another direction after losing a trailer tire, thanks to not being able to access air at ANY of the 5 gas stations and garages I stopped at prior, with a Toyota Tacoma onboard, 50 miles from the Canadian border. They were either out of order, access was blocked, or the hose a few feet too short and I couldn't get any closer without risking damage to someone's property.   https://postimg.cc/gallery/X5QJ55w

      I took a 12 second video on my iphone but the file is too big to upload. I will have to figure out how to extract the audio or just do another start with an audio recording.
