Allison Transmission’s new TC10 tractor transmission is now being offered on two International models. The ProStar and TranStar with MaxxForce 13 engines are available with the transmission. Navistar began accepting orders on Oct. 15 and expects initial deliveries to occur in the first quarter of 2014.

“The Allison TC10 is an innovative and efficient option that demonstrates our commitment to our International Truck customers,” said Nadine Haupt, director of alternative fuels and heavy duty on highway product marketing, Navistar. “Fleets that rely on the TranStar and ProStar models will find that spec’ing them with an Allison TC10 will further their fuel savings and operational goals.”

According to Allison test fleet users saw an average 5% fuel economy improvement with the TC10 over their current manual and automated manual transmissions. The TC10 is specifically designed for both city and highway tractor duty cycles and provides a blended architecture with full power shifts, a torque converter and a twin countershaft gear box. It is fully automatic and offers seamless shifting through 10 ranges.

“We have a long history of successful initiatives with Navistar and this launch of the TC10 into the tractor market furthers that model,” said Jim Wanaselja, vice president of North America marketing, sales and service for Allison Transmission. “The TC10’s cutting edge transmission technology, paired with Navistar’s offerings, will allow fleets the ability to save fuel while enjoying the performance, durability and reduced maintenance that the industry has come to expect from Allison Automatics.”

Rated up to 600 hp. and 1,700 lbs.-ft. of torque at launch, the TC10 is designed with 10 forward speeds and two reverse. It comes equipped with Allison’s newest generation of electronic controls which provide superior fuel economy features, prognostics to eliminate unnecessary oil and filter changes, and enhanced shift selector functionality.

 A five-year or 750,000 mile warranty is also included.
