Yes! My truck started doing this at around 24k. I took it in, and they have a permanent fix for this. I wish I knew what they did, but it was in the drive line/drive shaft.
Also, when I got the truck back, I had the dreaded shudder in first and second gear. And it was BAD! I took the truck back, and the service ticket said "Re-align drive shaft".
My truck has never been this smooth ever. It always has had a little shudder when accelerating briskly, but now, even that is gone. Take your truck to the dealer if under warranty and get this fixed. If they act stupid, find another dealer. This can be fixed!!!

I have had a few other wierd things happen with my trans. (2011 Eco-screw ).
1. From park, the trans would SLAM into gear when shifting from park into drive. It only did this a few times when it was brand new. It has not done it since.
2. To this day, the trans will shift really hard from 3 to 4 when just barely giving it throttle, only in city/side streets. It does this maybe once a month. Dealer cannot duplicate obviously. No ill effects that I can tell.
3. This next thing is what caused my clunk to start at 24k when coming to a dead stop/leaving from a dead stop. I needed to pass a slower car, but i was in heavy traffic (I call these people big gappers and they drive me nuts). I don't need you to be bumper to bumper, but anything over 100 yards and you are impeding traffic LOL. Anyway, I am going slow, maybe 20 mph so that means probably 4th gear, maybe 3rd i can't remember. I get on the throttle a bunch, but not floored. The guy decides to not let me pass, and pulls right in front of me in the center lane. I lift off the throttle completely, but the trans is now confused and did not find a gear yet, and is in limbo. The engine is reving at about 4k with me not giving it any gas, and then SLAMS into gear. I mean HARD. I was like holy crap I just effed up something.
It started doing the clunk thing right after that. The very next complete stop I did, it would feel like i had been bumped in the back when I would accelerate away from the stop. But the dealer fixed it under warranty about a week later. It has not done that since, and is really smooth now.
Also, It STILL shudder's ever so slightly in first and second when I"m towing about 6500 pounds. But, my Chevy Silverado (2007 Classic) also would shudder from a dead stop when towing my trailer. My new truck was doing the shudder thing ALOT worse before they did the driveline repair/re-alignment thing. It is very very slight in my truck now, so I don't plan on taking it back in for it. When not towing, no amount of throttle from a dead stop, even power braking and spooling the turbos, will cause a shudder anymore. My truck used to shudder just a little when hot rodding it from a dead stop, but not anymore.
