Kenworth announced that the new PACCAR TX-18 and PACCAR TX-18 Pro automated transmissions for Class-8, heavy on-highway and select off-highway vocational applications are now available for order. Both 18-speed transmissions build upon the efficiency of the PACCAR TX-12. The PACCAR TX-18 offers additional capability for heavy on-highway use for applications, such as heavy-haul transport. The PACCAR TX-18 Pro adds enhanced capabilities and unique features for extreme-duty vocational and other select off-highway applications. The new TX-18 and TX-18 Pro transmissions support maximums of 510 horsepower, 1,850 pound-feet of torque capacity and 140,000 pounds of gross combination vehicle weight.
The transmissions are equipped with an internal oil temperature sensor. The sensor shows transmission temperatures on the in-cab, 15-inch digital display. It also provides driver notifications in situations causing excessive temperatures.
The TX-18 and TX-18 Pro are standard with Kenworth’s column-mounted, right-hand shifter. The shifter places gear selection and engine brake controls at the driver’s fingertips for enhanced ergonomics, comfort and overall performance.
