Kenworth Expands PACCAR TX-12 PRO Automated Transmission Availability for PACCAR MX-13 Engines

Kenworth today announced its PACCAR TX-12 PRO automated transmission is now available with the PACCAR MX-13 engine for Kenworth’s T680, T880, and W990. The PACCAR TX-12 PRO is designed to optimize performance for both on and off-highway applications such as dump, plow, tankers, and more. The TX-12 PRO builds upon the standard TX-12, one of the most efficient on-highway automated transmissions.

“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.

The TX-12 PRO is optimally engineered to operate with all MX-11 and PX-9 engine ratings – up to 445 hp, 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, and more. The 12-speed gear set provides wide ratio coverage, allowing for excellent maneuverability around job sites.

The TX-12 PRO offers dual PTO openings – a bottom mount 8-bolt and 4-bolt rear mount for a combined 95 hp 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 finger tips 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.
