Peterbilt on Wednesday announced the availability of Paccar TX-12 automated transmissions with Paccar PX-9 engines for Peterbilt medium-duty Models 548, 537 and 536.
According to Peterbilt, both the standard PaccarTX-12 and TX-12 PRO versions seamlessly integrate with the PX-9 offering efficient operation and superior drivability.
“Together, the TX-12 transmissions and PX-9 engine, create an exceptional combination of efficiency and reliability,” says Jake Montero, assistant general manager, sales and marketing for Peterbilt. “Our medium-duty customers can spec confidently knowing this new powertrain configuration delivers increased productivity and an excellent driving experience.”
Peterbilt made the transmission available for its heavy-duty tractors earlier this year.
