PACCAR Introduces 12-Speed Automated Transmission

| August 24, 2017

Automated Transmission

PACCAR is introducing the new PACCAR Automated Transmission, the lightest heavy-duty transmission for on-highway commercial vehicles.

The freshly unveiled PACCAR transmission is designed to complement the PACCAR MX engines and PACCAR axles. Kenworth and Peterbilt will begin offering the new PACCAR Automated Transmission to North American customers in October 2017.

The new Automated Transmission is primarily designed for line-haul applications up to 110,000 lbs. Gross Vehicle Weight. It is available for engine ratings up to 510 HP and 1,850 lb.-ft. of torque and features tightly integrated electronic communications with the PACCAR MX engine.

Equally significant, the improved automated transmission offers an impressive overall gear ratio, which in turn should provide improved low-speed maneuverability.  Plus, the transmission is up to 105 lbs. lighter than comparable transmissions. Adding to the value of the new transmission is that it boasts a 750,000-mile oil change interval, which is the longest available for line-haul applications, reducing maintenance costs and increasing uptime.

The transmission also 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. Additionally, PACCAR’s new column-mounted shifter puts gear selection and engine brake controls at the driver’s fingertips for better ergonomics and improved performance.
