Peterbilt Motors recently added the PACCAR TX-18 and TX-18 Pro automated transmissions to the family of PACCAR TX transmissions.
The all-new TX-18 is available in Peterbilt Models 567, 389, and 579 equipped with PACCAR MX engines, the company said.
The TX-18 was built from the ground up to provide productivity, efficiency, and uptime for a superior driver experience. The TX-18 is designed to work exclusively with the MX-11 and MX-13 engines. It is a workhorse for a variety of vocational applications, including heavy haul, dump truck, and cranes. The combination of the TX-18 transmission and MX engine provides up to 1,850 pound-feet of torque and is rated up to 140,000 pounds GCWR.
The TX-18 features a high-pressure diecast aluminum casing, one-piece serviceable input shaft, helical gearing, precision lubrication system, extreme duty clutch, and an integrated clutch housing, Peterbilt said.
The TX-18 can be configured with an optional transmission cooler to help keep it operating efficiently with demanding workloads. The transmission features four application-specific calibrations and comes standard with two PTO openings capable of a combined 160 hp.
The TX-18 has good low-speed maneuverability with small, even gear steps through all 18 forward speeds to deliver a smooth driving experience. A high-speed reverse with up to six configurable speeds is available in the TX-18 Pro to increase productivity in demanding applications. An automotive-style, stalk-mounted shifter with drive, neutral, reverse and manual modes ensure the operation of the TX-18 is simple and intuitive.
“The integration of the new TX-18 and TX-18 Pro with PACCAR’s line of MX engines further enhances Peterbilt’s ability to provide our customers the lowest cost of ownership, best-performing trucks in the industry,” said Jacob Montero, Peterbilt general sales manager. “The gains in productivity, efficiency, uptime, and the ease of use for drivers make these transmissions a must-have.”
