Paccar updated its MX-11 and MX-13 engines this year, shedding weight and extending oil drains in the process. But it was the company's automated transmission - developed through the new Eaton-Cummins Automated Transmission Technologies - that garnered the most attention during recent product launches.
MT VERNON, WA - Paccar has unveiled a 12-speed automated transmission, rounding out a proprietary powertrain with the promise of better fuel economy and smoother shifts along the way. Developed over three years in a partnership with Eaton, the transmission will be released into the market this October. "The Paccar automated transmission is engineered to work seamlessly with Paccar MX engines and Paccar axles," says Landon Sproull, Paccar vice president. It will support linehaul applications with Gross Vehicle Weights up to 110,000 pounds, and engines delivering up to 510 horsepower and 1,850 lb-ft of torque. The first units will be an option with MX-13 engines.
