LISLE, Ill. — Navistar has announced a complete line of automated and automatic transmissions for the International ProStar and TranStar vehicles.
“At Navistar we continue to evaluate technologies aimed at reducing the cost of operations for our customers, but the greatest variable today in fuel economy is the driver,” said Bill Kozek, president of North America Truck and Parts, Navistar. “Our portfolio of fully automated transmissions reduces the variance between expert drivers and first-timers by electronically monitoring vehicle speed, grade, weight and more to select the best gear for the engine. This not only improves efficiency, but it will extend the life of the driveline.”
Among the offerings are the Cummins Eaton Smart Advantage, the UltraShift Plus LSE and the Allison TC10. The Cummins/Eaton collaboration features a 10-speed automated manual transmission mated to the Cummins ISX15 engine. The engine/transmission combination have been optimized for maximum performance, the companies claim. Cummins and Eaton say fuel economy improvements of 3-6% can be achieved. The Smart Advantage is available for order now.
Also available is the UltraShift Plus LSE, which Eaton designed specifically for Navistar. The new 16-speed direct drive automated manual maximizes fuel efficiency in linehaul applications, with fuel savings of up to 6% possible, according to Eaton. A small 17% step allows for quick, precise gear changes.
The Allison TC10 is the first fully automatic transmission for the Class 8 market, and is available on International ProStar and TranStar trucks with MaxxForce 13 engines. Allison says its transmission can save fuel to the tune of 5%. International trucks with the TC10 will be available for delivery in early 2014, Navistar has announced.
