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.

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.

Welcome to the forum. What year and what engine do you have?

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

Are you sure the shudder isn't your DFM kicking on and off?

[Frenchie604]

3.0 diesels don’t have cylinder deactivation as far as I know 

[TrueBlue]

Ah, sorry. Didn't notice you were running the diesel

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.
