The Paccar TX-18 PRO transmission is designed around productivity, efficiency and uptime for on- and off-highway applications. It was made for a variety of vocational applications, including heavy-haul, dump truck, wreckers and cranes. The rock-free mode is now standard on the transmission. The transmission also features a new off-road calibration.
“The integration of these new features on the Paccar TX-18 PRO transmission enhances Peterbilt’s ability to provide the best-performing trucks in the industry and deliver productivity, efficiency and uptime to our customers,” said Jake Montero, assistant general manager of sales and marketing at Peterbilt.
The off-road calibration mode can be switched on using a stalk-mounted shifter. The system learns road terrain and surface conditions and responds automatically to minimize unnecessary shifting and maximize time in gear in challenging terrain. The rock-free mode can be engaged if off-road conditions impact maneuverability.
The Paccar TX-18 PRO is paired exclusively with the Paccar MX-11 and MX-13 engines for Peterbilt Models 579, 567, 589, 389, 367 and 365. Peterbilt said the new transmission provides up to 1,850 pound-feet of torque and is rated up to 140,000 pounds GCWR when paired with a Paccar MX engine.
