Brock Childress drives this 2014 Kenworth W900L owned by Smitty’s Heavy Hauling in Texas. The rig is powered by a 650-horsepower Cummins with an Eaton 18-speed and 46,000-pound rear axles. The truck is used to haul heavy equipment in south Texas.
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.
