Wayne Byrd of Monticello, Miss., makes oil field and natural gas runs in his 2011 International Lonestar, usually in Texas and Oklahoma. Byrd’s business, Catfish Cruisers Inc., is leased to Kentucky-based TMT Inc. The truck sports a few engine mods and a custom paint job by Bictor’s Tint and Graphics of McComb, Miss., and it’s powered by a 550-hp Cummins engine and 18-speed transmission.
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.
