I had same issue I just turn off the truck wait until screen go completely off and turn on again, also few days ago I went to Peterbilt and replace the transmission shifter and works good now.
Try putting it in neutral as you are driving down the road. If I do that and coast for several hundred yards it goes away. There is a recall on the stalks but no stalks available at this time....go figure! This will be the 4th new stalks in this tractor and it's only a year and a half old....Pete 579
@@quoshon100 not exactly, but I have a theory. It may have been because I tried to shift and switch between gears at the same time without realizing. It would cause the computer to glitch and force me to stop. But that doesn't solve all the instances. I did notice that it would not happen if If I shifted down while below 63 MPH.
