Update I got my truck back today after the dealership performed a new flush with the Mobil 1 ATF. On the drive home notice a huge difference right away much smoother shift damn near flawless. Hopefully it holds up. I’ll be sure to keep you’ll updated.

So I'm having the same issue with my 16 Denali took it in back in Nov of 18 damn car was shaking as it a pitbull had it by the roof. It was the torque converter they did a flush and reprogram and sent me about my way said something about I had to drive it 500 miles to get the fluid throughout the transmission.

March of 19 came the same issues seem to come back I take it in the dealership said the vehicle is performing as normal. I take it to another dealership and they also mentioned the same performing as normal.

Take the vehicle in this past Friday for brakes get the vehicle back drive about 10 miles truck stalls torque converter again after I freaking told them I had issues. Truck currently has 58k on it so still a little left on the warranty but I'm thinking their going to do another half ass fix and I'll be out of the warranty.

I swear call me crazy I'm so ready to go back to Acura
My 2016 Yukon Denali had torque converter shudder on the highway (felt like square tires) at 32,000 miles. The issue is the 8 speed transmission - Pure junk. I turned it in for a 2019 with the 10 speed and so far it's awesome.
