Graham and Suzanne O’Donnell, of Phoenix, own this 2006 Peterbilt 379, powered by a Cummins ISX. Though the truck is all stock now, the couple plans to add a bull bar, 7-in. straight pipes and other chrome.
Affected tractors are equipped with an automated Eaton UltraShift Plus or Eaton Advantage Transmission with right hand stalk shifter. In the affected trucks, the display on the instrument panel can indicate “N” when the shifter is set into “D” or “R,” causing the truck not to move.
