The advanced PACCAR Automated Transmission is available for order immediately on Peterbilt Models 579 and 567, the company announced.  The 12-speed automated transmission is the latest addition to the proprietary PACCAR Powertrain and introduces game-changing gains in efficiency, drive-ability and durability for the successful Peterbilt on-highway models.

“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 PACCAR Transmission, the proven PACCAR 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. Peterbilt trucks equipped with the PACCAR Powertrain deliver an unparalleled driver experience while positively impacting the bottom line of our fleet and owner operator customers.”

The PACCAR Transmission was purpose developed as an automated transmission for heavy-duty linehaul applications. The seamless integration with the PACCAR MX-13 allows the Peterbilt Models 579 and 567 to offer a new level of driver friendly performance, with class-leading low speed maneuverability and smooth, intuitive shifting. The PACCAR Transmission is able to select the starting gear and make shift decisions based on grade, vehicle weight, engine torque and throttle position.

The PACCAR Transmission was designed to maximize uptime and reduce the overall cost of ownership:  an industry-exclusive fluid pressure sensor provides advance warning of low oil situations while an oil-coalescing air filter protects the transmission from contamination. The PACCAR Transmission boasts a cooler-less design and extended maintenance intervals and is backed by a comprehensive five-year / 750,000 mile warranty.

The PACCAR Transmission is available for order immediately on MX-13 equipped Models 579 and 567 scheduled for production after October 16.  Availability of the PACCAR Transmission with the 10.9-liter PACCAR MX-11 Engine is scheduled for early 2018.
