Eaton launches dual-clutch transmission for medium-duty trucks

Procision can cut fuel use up to 10% for work trucks.

September 5, 2014

Galesburg, Michigan – Eaton Corp. has introduced Procision, a new line of medium-duty dual clutch transmissions, that delivers 8% to 10% better fuel economy than a similarly equipped vehicle with a torque converter automatic.

Scheduled to be available in the North American market mid-year in 2015 and available globally in the future, the new 7-speed transmissions feature a dual clutch design and electronic shifting that uses grade, vehicle weight, and throttle input to provide optimal fuel efficiency and smooth, continuous delivery of torque to a vehicle’s wheels under all shift conditions.

“Small businesses rely on their class 6 and 7 medium-duty trucks to deliver goods and perform tough jobs on a daily basis,” said John Beering, senior vice president and general manager, Eaton Commercial Vehicle Transmission. “The all-new Eaton Procision is the first dual clutch transmission for class 6-7 in North America. Its smart features deliver more savings and driver confidence, and is the ideal transmission solution for medium-duty applications.”

The dual clutch module is fully contained within the transmission, hydraulically controlled, and oil cooled for extended life. A five-spring damper is used to control torsional vibrations and is fully sealed to eliminate contamination.

Features such as Eaton Dynamic Shifting allow the transmission to automatically switch between economy and performance shift schedules based on mass, grade, and driver demand. Base shift results are modified dynamically based on available torque, engine acceleration and grade.

Economy and performance shift tables can be adjusted to tune an overall calibration to meet any customer’s specific needs.

Procision has three standard power take-off (PTO) openings. PTO functionality can be enabled via the ServiceRanger software by dealerships after purchase. This flexibility is a competitive advantage for Procision and enhances value to both first owners and the secondary market.
