PACCAR TX-12 Pro automated transmission introduced in Kenworth trucks

The new transmission will get its start in the Kenworth T680 and T880 trucks.

PACCAR has introduced the new TX-12 Pro automated transmission for Class 6-7 and light Class 8 vocational applications. The company says it builds upon the existing PACCAR TX-12 transmission.

Currently, the new transmission is available with select Kenworth Class 8 models, including the T680 and T880 equipped with the PACCAR MX-11 or PACCAR PX-9 engines. Later this year, the transmission will be available in Kenworth Class 6-8 medium duty models, including the T280, T380, and T480 equipped with the PACCAR PX-9 engine.

The company says the PACCAR TX-12 Pro is engineered to operate with all MX-11 and PX-9 engine ratings—up to 445 HP, 1,700 lb.-ft. of torque and 70,000 lbs. of gross combination vehicle weight (GCVW).

PACCAR says the TX-12 Pro features many of the TX-18 Pro’s enhanced capabilities for vocational and off-highway applications, including PACCAR’s Extreme Duty clutch for improved low-speed maneuvering, Rock Free mode to help trucks get unstuck in mud or sand, an off-highway calibration tuned for changing soil conditions and more. The company says the 12-speed gear set provides wide ratio coverage to improve maneuverability around job sites.

“The new TX-12 Pro transmission is a welcomed addition to the PACCAR transmission family and will be an excellent powertrain component for our vocational medium-duty customers and customers operating Class 8 trucks that are in light vocational applications which don’t require the power of the TX-18 Pro,” said Jim Walenczak, Kenworth general manager and PACCAR vice president. “The TX-12 Pro builds off the proven technology of the TX-12 and TX-18 Pro to be an efficient and durable product for on and off-highway applications.”

Kenworth adds that the TX-12 Pro offers dual PTO openings – a bottom mount 8-bolt and 4-bolt rear mount for a combined 95 HP capacity. The transmission is equipped with an internal oil temperature sensor, which displays data on the in-cab 15-inch digital screen, and provides driver notifications in situations causing excessive temperatures. The company adds that the PACCAR TX-12 Pro follows suit with the TX-12 and TX-18 transmission models, keeping the column-mounted, right-hand shifter.
