DENTON, Texas — The advanced PACCAR automated transmission is available for order immediately on Peterbilt Models 579 and 567, the OEM said Wednesday.

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, according to Kyle Quinn, Peterbilt general manager and PACCAR senior vice president.

In conjunction with the transmission announcement, Peterbilt said it had introduced a new, ergonomic column-mounted shifter on the Models 579 and 567. The new shifter will be standard on trucks equipped with the automated PACCAR Transmission as well as those equipped with Eaton Advantage and Ultra Shift AMTs.

“The PACCAR Transmission offers best-in-class performance, reliability and low cost of operation,” Quinn said. “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 purposely developed as an automated transmission for heavy-duty linehaul applications, Quinn said, adding that 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.

It 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 offers a cooler-less design and extended maintenance intervals and is backed by a comprehensive five-year, 750,000-mile warranty.

The 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.

The new shifter, located on the right-hand side of the steering column, features a multi-mode design and allows control of all transmission and engine brake functions, including gear selection, engine brake mode and manual shifting. The column-mounted shifter places controls at the driver’s finger tips, minimizing distractions and allowing an increased focus on road conditions and surrounding traffic.

“The column-mounted shifter takes the ergonomics of the Models 579 and 567 to a new level,” said Scott Newhouse, Peterbilt chief engineer. “The column-mounted shifter was designed based on in-depth studies of driver behavior and ergonomics. This new design also allowed us to improve on the usability of our dash by eliminating engine brake control switches.”

With the implementation of the column-mounted lever, a newly designed pinch valve located on the dash has replaced the traditional lever for trailer brake activation, greatly enhancing control during coupling and uncoupling maneuvers, company spokesmen stated.

The column-mounted shifter will be available on Models 579 and 567 ordered with automated transmissions beginning in October 2017.
