The TX-12 Pro automated transmission delivers enhanced performance for plows, dumps, tankers, and more.
The Paccar TX-12 Pro automated transmission is now available with the Paccar MX-13 engine for Kenworth’s T680, T880, and W990 models.
This transmission is designed to optimize performance for both on- and off-highway applications such as dumps, plows, tankers, and more. The TX-12 Pro builds upon the standard TX-12 on-highway automated transmission.
“The TX-12 Pro transmission’s integration with the MX-13 engine is a welcomed addition for our Class 8 customers that operate in vocational applications,” said Kevin Haygood, Kenworth’s assistant general manager for sales and marketing, in a news release.
The TX-12 Pro is optimally engineered to operate with:
- MX-11 and PX-9 engine ratings up to 445 horsepower and 1,700 lb.-ft. of torque
- MX-13 engine ratings up to 455 hp and 1,650 lb.-ft. of torque, and 70,000 pounds of gross combination vehicle weight (GCVW).
The Paccar TX-12 Pro features many of the TX-18 Pro enhanced capabilities for vocational and select off-highway applications, including:
- Paccar’s Extreme Duty clutch for improved low-speed maneuvering
- Rock Free mode to help trucks get unstuck in mud or sand
- An off-highway calibration tuned for changing soil conditions
The 12-speed gear set provides wide ratio coverage, allowing for excellent maneuverability around job sites, according to Kenworth.
The transmission also offers dual PTO openings — a bottom-mount 8-bolt and a 4-bolt rear mount — for a combined 95 horsepower capacity.
The transmission is equipped with an internal oil temperature sensor. The sensor shows transmission temperatures on the in-cab 15-inch digital display and provides driver notifications in situations causing excessive temperatures.
As with all Paccar TX-12 and TX-18 transmission models, the TX-12 Pro is standard with Kenworth’s driver-friendly column-mounted, right-hand stalk shifter. The shifter places gear selection and engine brake controls at the driver’s fingertips for enhanced ergonomics, comfort, and overall performance.
Oil maintenance intervals for the TX-12 PRO are 250,000 miles, and the clutch is maintenance-free.
