Paccar launches lightest HD automated transmission for on-highway CVs

Paccar has announced a new 12-speed automated transmission (AT) and column-mounted shifter to improve fuel economy and driver ergonomics in Peterbilt and Kenworth models in North America beginning in October. The transmission and shifter were jointly developed to provide a superior shifting experience while reducing weight.

“The Paccar Transmission offers best-in-class performance, reliability and low cost of operation,” said Kyle Quinn, Peterbilt general manager and Paccar senior vice president. “With the availability of this innovative transmission, the proven MX-13 engine and the efficient Paccar Axle, the Peterbilt Models 579 and 567 can now be spec'd with the industry's most advanced proprietary drivetrain.”
