The Eaton Procision line of dual-clutch, automated-manual transmissions will be available on International DuraStar medium-duty trucks in late 2015, Navistar announced.

Through its partnership with Eaton, Navistar says it will be the first to market with the new transmission line which features a dual-clutch design and electronic shifting. The transmission takes into account grade, vehicle weight and throttle input to provide optimal efficiency and a continues delivery of torque.

"Customers told us that they wanted features that made their trucks easier to drive," said Jeff Carpenter, Eaton’s medium-duty Procision engineering manager. "So, we engineered a host of features that instill confidence and maximize efficiency for operators with routes on hilly, difficult terrain, or those who navigate tight turns and traffic as part of an urban route."

The dual-clutch technology allows for more efficient acceleration from a stopped postion and optimizes shift points to efficiently get to the highest gear. Gear changes are made by swapping the engine torque between clutches with the next gear preselected. The dual-clutch module is fully contained within the transmission and is hydraulically controlled and oil cooled.

The transmission features Eaton Dynamic Shifting which allows it to automatically switch between economy and performance shift schedules based on mass, grade and driver demand. Economy and performance shift tables can be adjusted to tune an overall calibration to meet a customer’s specific needs.

Eaton Procision transmissions use a synthetic transmission fluid that provides component protection while reducing maintenance costs as part of 150,000-mile or 4-year lube and filter change intervals. The transmission is backed by a 3-year, unlimited mile warranty which covers the complete system including dual-clutch module.
