I have the PACCAR drivetrain. So after a recent service and supposable computer updates I am now having an intermittent issue with getting a Transmission Fault. This happens when moving around to a dock at a shipper/receiver and going in forward to reverse. Cycling key a few times and fiddling with shift knob seems to make it go back to working. No codes remain on dash.
How worried should I be about this leaving me stranded?
