I’m not experiencing a shudder at speed, only when downshifting into first (when doing a stop and go). I notice it is much more apparent when I first turn the vehicle on after the powertrain has cooled down. My current “work around” is starting it up, putting it into Tow/Haul mode, and driving off. Because it forces to hold first longer and down shift faster, there isn’t a lag or shudder… but fuel economy suffers.
