When coming off of the highway and slowing down but not to a complete stop then accelerating again the truck will have a shuddering/bucking condition. Feels like when you don't downshift a manual transmission vehicle and try to accelerate. It did it once when about 3 weeks old and a few other times since. Had the solenoid recall done and thought that would've taken care of it but now it seems worse. Took a tech for a ride and of course it wouldn't do it. The reset the adaptives and it seemed better for about a week then I felt it again today. It's either not downshifting from 3rd to 2nd fast enough or the lock up converter isn't unlocking when it should. Doesn't matter hot or cold. I will have the shift indicator display active so I can see what gear it seems to be hanging up on.
