I have a 2016 5.3 8 speed with about 9k miles. Headed to the dealer next week. I've loved my 8 speed thus far. Some minor issues, but nothing that bugs me. I've recently had two shudder events. Both accelerating our of a corner and the truck won't shift and starts shaking terribly. Roads were getting icy so I was running in Auto 4wd. At first I thought it was traction control, but no light and too violent. Anyone else have this type of shuddering upon acceleration? Feels almost like a manual transmission stuck in a high gear bogging down.
