Navistar Offering New Transmission Options

Posted on October 21, 2013

Navistar, Inc. announced it will go to the market with a portfolio of fully automatic and automated manual transmissions that will be available on International ProStar and International 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."

The company's portfolio of fully automatic and automated manual transmissions includes the Cummins Eaton Smart Advantage, the Eaton UltraShift Plus LSE and the Allison TC10 transmissions.

Available on the International ProStar, the Cummins Eaton Smart Advantage is a 10-speed automated manual transmission paired with the Cummins ISX15 engine. Cummins and Eaton estimate that drivers can achieve between 3 and 6% improved fuel economy. Navistar is the first to market with this product combination and it is available for order now.

Eaton's UltraShift Plus LSE transmission is designed exclusively for Navistar. The new 16-speed direct drive automated mechanical transmission maximizes fuel efficiency in linehaul applications and Eaton testing has validated drivers can achieve 6% improved fuel economy. Navistar said.

Allison’s TC10 transmission is available on International ProStar and International TranStar vehicles with MaxxForce 13 engines.

Rated up to 600 hp and 1700 lb.ft. of torque at launch, the TC10 has 10 forward speeds and two reverse and is equipped with Allison's newest generation of electronic controls. It will be available for delivery in early 2014.
