Update - I picked up the truck today. They found the gears 4-6 clutch hub was broken. The hub was replaced, along with the fluid, filter, pump seal, and it as flushed. They did mention that it was weird no check engine light or codes were saved. They forwarded this to GM for review. It drives okay. Same as before just works now. I'm still on edge as this is just 12,500 miles in... What else is going to break? I guess I just have to drive it. This will just be in the back of my mind. I have to say the dealer I brought it to was not the one I use for regular service, they were great. They have a dedicated in house transmission tech. Super quick turn around. Gave me a loaner on the spot without reservation... Someone called for a loaner when I brought the truck in and they were turned down.

Hey guys just want to share my transmission adventure with everyone. I have a 2016 Silverado LT with 12500 miles, 5.3 with 3.42 gears. I've always had a slight vibration at higher speeds. 65-80 mph but nothing extreme and clunky shifting. Dealer of course said it was normal. Occasionally would get a good clunk on downshifts under a load. My house is on a steep hill so usually when going up then slowing down at the top of the hill I would feel it. About 5000 miles ago it began clunking when in stop and go traffic on up and downshifts. Again dealer said it was normal. Lately it was clunking between 30-50 mph usually when merging into traffic, up shifting. Had all "computer" recalls done at the dealership. This morning while on the highway in the third lane going around 50, it felt as if I hit a large pothole, but there was none and the engine just revved. It just popped out of gear. I pulled over and tried to go. It would shift fine from 1-3 gear then it revs and would not catch 4th. I pulled over again and tried it in manual mode. Same thing, would not engage 4-6th gear. I called the dealership they told me to turn it off and on, open and close the door to reset the transmission computer. Same thing would not go past 4th gear. So its in the shop now. I'll let you guys know what the deal is. I'm very disappointed as this is my first Chevy and first pickup truck. I know I bought a truck but this thing lacks any finesse and new car feel. The vibration, transmission issues, and shitty idle make it feel like a POS. I know this is an unfair comparison and their quality has gone down in the last few years, but my wife and I have always leased Toyota SUV's. From day one to the vehicles return they never had an issues and felt new. My father has a Tacoma, again not a apples to apples comparison, and he has had other issues like rust. But his trucks motor and transmission have been bullet proof, I've pulled a 18 foot cuddy cabin with his truck for years and never a hiccup. The only issues came when he put "off-road" tires, then he complained about vibration but that was expected.
