Kenworth on Wednesday announced is was making the Paccar Automated Transmission available for order on its T680 equipped with the MX-11 engine.
Previously, the Eaton Cummins engineered transmission was available matched only to an MX-13.
Kurt Swihart, Kenworth marketing director, says the lightweight transmission, which is 105 pounds lighter than comparable models, is a good match for the MX-11, which is 400 pounds lighter than 13-liter engines.
“The proprietary Paccar Powertrain, which includes Paccar’s 10.8-liter MX-11 engine, 12-speed transmission and 40,000-pound tandem rear axle, provides outstanding performance through weight savings, increased fuel efficiency and enhanced driveability for Kenworth T680s operating in linehaul and regional haul applications,” he says.
The Paccar Transmission is paired with Kenworth’s new column-mounted shifter, putting gear selection and engine brake controls at the driver’s fingertips for better ergonomics and improved performance. The shifter position on the steering wheel column also frees up dash space by eliminating engine brake control switches.
