Navistar is adding a lightweight transmission option to its International ProStar tractor. The Tremec 10-speed manual transmission is now available on ProStar tractors with Navistar’s 13L engine.
Tremec offers a wide range of high torque-to-weight ratios designed for weight sensitive over-the-road and city applications, Navistar said.
“Tremec transmissions are not only known in the automotive industry for a wide variety of high-performance cars, but Tremec components are used in transmissions throughout the commercial transportation industry,” said Jodi Presswood, general manager, Heavy-Duty Truck Product Line, Navistar. “This lightweight transmission reduces the weight of the vehicle while also providing our customers with yet another choice.”
Navistar will offer four Tremec transmission options paired with the company’s 13L engine, available with horsepower ranges of 370 to 450 hp. and 1,350-1,700 lbs.-ft. torque for line haul and regional haul applications in the United States and Canada.
The company also offers Tremec transmissions as an option in its ProStar with Cummins ISX15.
