Allison Transmission Holdings Inc. announced that the new TC10 tractor transmission is now offered on Navistar's International ProStar and TranStar models with MaxxForce 13 engines with SCR. This is the first offering of the fully automatic TC10. Navistar began accepting orders on Oct. 15 and expects initial deliveries to occur in the first quarter of 2014.

Test fleet users achieved an average 5% 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.

Rated up to 600 horsepower and 1,700 pounds-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.
