Kenworth has announced wider availability of the Paccar TX-12 Pro automated manual transmission paired with Paccar MX-13 engines.

The transmission can be mated to the MX-13 in Kenworth T680, T880, and W990 trucks, designed for optimum performance in both on- and off-highway applications, including dump, plow and tanker.

“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 designed 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 lb. of gross combination vehicle weight (GCVW).

The TX-12 Pro offers dual PTO openings – a bottom mount 8-bolt and 4-bolt rear mount for a combined 95 hp capacity, Kenworth announced.

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.

Oil maintenance intervals for the TX-12 Pro are 250,000 miles, and the clutch is maintenance-free.
