Kenworth is expanding availability of its Paccar TX-12 PRO automated manual transmission, bringing it to several models within the company’s medium-duty line.
The vocational transmission is now available on the Kenworth T380 and T480, when matched with the Paccar PX-9 engine.
“Versatility and durability are what the Kenworth T380 and T480 are all about,” says Kevin Haygood, Kenworth’s assistant general manager for sales and marketing. “For customers who prefer an AMT over an automatic option, the TX-12 PRO is the solution. It gives customers great performance and toughness when they use the T380 or T480 in demanding vocational applications.”

The Paccar PX-9, with one of the highest power-to-weight ratios in the industry, can be spec’d with peak horsepower ranging between 260- and 380 for on-highway and vocational use; up to 450 hp with 1,250 lb.-ft. of torque for fire service vehicles, Kenworth says.
The Paccar TX-12 PRO was designed for rugged service and low-end drive performance applications like dump truck, snowplow or in chassis-mounted tanker configuration. Additionally, Kenworth states the TX-12 PRO features an Extreme Duty clutch for low-speed maneuvering, and Rock Free mode to help trucks get unstuck in mud or sand. Plus, it has an off-highway calibration tuned for changing soil conditions. The 12-speed gear set provides wide ratio coverage, the company adds, allowing for excellent maneuverability without sacrificing fuel economy at highway speeds.
Additionally, for those applications requiring a PTO, The TX-12 PRO is available with dual openings — a bottom mount 8-bolt and 4-bolt rear mount for a combined 95 hp capacity.

And to monitor performance and to ensure long-life, Kenworth says the transmission and clutch are both equipped with internal oil temperature sensors. Their temperatures can be displayed on the in-cab 7-in., digital display and can provide driver notifications in situations causing excessive temperatures.
Oil maintenance intervals for the TX-12 PRO are 250,000 miles, and the clutch is maintenance-free, Kenworth adds.
