Paccar’s proprietary 12-speed transmission
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.
Twin Stick to mDRIVE
During a visit to the Mack Customer Center and Museum, I had a chance to compress almost 60 years of transmission history into a single day. If you think we have a driver shortage today, thank your lucky stars we aren't trying to coax new drivers into the industry with twin stick gearboxes!
