Paccar Inc. is recalling approximately 1,938 2017-2018 Kenworth T680 and T880 trucks as well as Peterbilt 567 and 579 trucks equipped with an automated Eaton UltraShift Plus or Eaton Advantage transmission with a right-hand stalk shifter because the transmission gear display may display incorrectly.
For example, the display can indicate Neutral when the driver set the shifter into Drive or Reverse, which results in the failure of the truck to move. A vehicle that does not move as expected can increase the risk of an accident.
To rectify the problem, Paccar will notify owners and dealers will install a complimentary transmission software update. The recall is expected to begin on April 2. Truck owners can reach Kenworth customer service at (435) 828-5000 or Peterbilt customer service at (940) 591-4000. Paccar's reference number for the Kenworth recall is 18KWA; the manufacturer’s reference number for the Peterbilt recall is 118-A.
