KIRKLAND, Wash., Dec. 19, 2017 – Kenworth announced today that, beginning in January, the 12-speed PACCAR Automated Transmission and right-hand column-mounted shifter will be standard equipment on linehaul and regional haul applications of Kenworth’s on-highway flagship T680. The action completes the Kenworth T680’s transition to the PACCAR proprietary standard powertrain of engine, transmission and tandem rear axle to maximize efficiency and driveability.
“The seamless integration of the proprietary PACCAR Transmission with the MX-13 engine and tandem rear axles in the Kenworth T680 provides new levels of fuel economy and weight savings performance, and a powertrain second to none providing benefits to both fleets and individual truck operators,” said Kurt Swihart, Kenworth marketing director. “In 2017, approximately 70 percent of our linehaul customers purchased automated transmissions, up from about 30 percent in 2013. We’ve received a very positive response from fleets involved in the PACCAR transmission’s testing and validation program.”
Kenworth’s new column-mounted shifter for the PACCAR Transmission places gear selection and engine brake controls at the driver’s fingertips for better ergonomics, comfort and overall performance. With the shifter right there on the steering column, the driver does not have to reach for it. This placement also frees up dash space by eliminating engine brake control switches.
The PACCAR Transmission is ideal for linehaul and regional haul applications up to 110,000 lbs. gross vehicle weight. The PACCAR MX-13 engine is available with ratings up to 510 hp and 1,850 lb.-ft. of torque. The transmission is up to 105 lbs. lighter than comparable transmissions, allowing for greater payloads. The PACCAR Transmission also offers the best overall gear ratio coverage and provides excellent low-speed maneuverability.
The new PACCAR Transmission provides a 750,000-mile oil change interval that is the longest available for linehaul applications. Other features include a maintenance-free clutch, and an internally routed electrical system that minimizes exposure to the elements. The fluid pressure detection system protects the gears from low fluid conditions.
