Kenworth has introduced the Paccar TX-12 Pro automated transmission for its Class 6-8 medium duty models, including the T280, T380, and T480 equipped with the Paccar PX-9 engine.

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

“The new TX-12 PRO transmission 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, VP and general manager. "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.”

The transmission is equipped with an internal oil temperature sensor. The sensor shows transmission temperatures on the in-cab 15-inch digital display and provides driver notifications in situations causing excessive temperatures. 

The TX-12 PRO is standard with Kenworth’s column-mounted, right-hand shifter. The shifter places gear selection and engine brake controls at the driver’s finger tips, providing enhanced ergonomics and comfort.
