Anybody else have further issues on this? I have a 2018 1500 5.3l 8-speed. I have never had the higher speed shutter (50-60 mph), but more of a jerking motion when the truck is almost coming to a stop but barely rolling forward. It also tends to have a solid clunk even when lightly applying the throttle after coasting for a few seconds at city speeds. I got the newest full syntheic ATF put in a couple weeks ago, and no change. I have the E-assist model (which I'm annoyed by the start/stop feature), but not sure if that changes anything. Has anybody had similar behavior? Maybe had the torque converter replaced? Maybe a 2019 transmission or torque converter installed being that they redesigned it for 2019? Taking it into the dealer again next week and they are going to try and diagnose further and compare it to other trucks. My dealer in Watsonville, CA has actually been working with me very well on this issue. Any input?
