Peterbilt recently introduced Off-Road Calibration and Rock-Free Mode for the Paccar TX-18 PRO transmission, which is designed to perform in a variety of vocational applications, including heavy haul, dump trucks, and wreckers.
The TX-18 PRO transmission is available in Peterbilt models 579, 567, 589, 389, 367, and 365. It’s exclusively paired with Paccar MX-11 and MX-13 engines, Peterbilt said. The powertrain combination provides up to 1,850 lb.-ft. of torque and is rated up to 140,000 lbs.
“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,” Jake Montero, Peterbilt assistant general manager for sales and marketing, said in a news release.

Users can engage Rock-Free Mode, which now comes standard on the TX-18 PRO, when off-road conditions impact maneuverability. Once engaged, the transmission can quickly shift between drive and reverse to rock-free, fully enabling the truck, before automatically returning to its default setting, the manufacturer said.
