PACCAR launches 12-speed automated transmission

Aug. 29, 2017

PACCAR has introduced the new PACCAR Automated Transmission, the lightest heavy-duty transmission for on-highway commercial vehicles, PACCAR officials said August 22 during a press conference at the PACCAR Technical Center.

The PACCAR transmission is designed to complement the superior performance of PACCAR MX engines and PACCAR axles. Kenworth and Peterbilt will begin offering the PACCAR automated transmission to North American customers in October.

“The PACCAR Automated Transmission is engineered to work seamlessly with PACCAR MX engines and PACCAR axles and provide industry-leading performance,” said Landon Sproull, PACCAR vice-president. “Together, PACCAR Powertrain components deliver superior fuel economy, uptime, and driver satisfaction--top priorities for our customers.”

The PACCAR Automated Transmission is designed for linehaul applications up to 110,000 pounds gross vehicle weight. It is available for engine ratings up to 510 horsepower and 1,850 lb-ft of torque and features tightly integrated electronic communications with the PACCAR MX engine.

The PACCAR Automated Transmission offers the best overall gear ratio coverage available providing excellent low-speed maneuverability and the transmission is up to 105 pounds lighter than comparable transmissions, savings that customers can use to haul more payload. The 750,000-mile oil change interval is the longest available for linehaul applications, which reduces maintenance costs and increases uptime.

The transmission includes a differentiated fluid pressure detection system that protects the gears and shafts from low fluid conditions and allows PACCAR to offer industry-leading warranty coverage. Other features include a maintenance-free clutch and an internally routed electrical system to maximize durability. PACCAR’s new column-mounted shifter puts gear selection and engine brake controls at the driver’s fingertips for better ergonomics and improved performance.
