"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." Test fleet users achieved an average 5 percent fuel economy improvement with the Allison TC10 tractor transmission 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 smooth, seamless shifting through 10 ranges. This optimizes acceleration and fuel economy, making the transmission especially ideal for distribution applications where a tractor-trailer splits its work cycle between city and highway conditions. "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 horsepower and 1,700 pound-feet 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.
