MARSHALL, Mich. — Eaton Corp. unveiled a new automated transmission for Classes 6-7 medium-duty trucks that company officials said will boost fuel economy 8% to 10% over torque-converter automatics.
The dual-clutch Procision debuted at Eaton’s proving grounds and test track Sept. 4. Reporters took drives in Classes 6 and 7 trucks around a track and up and down varying grades.
“Small businesses rely on their Class 6 and 7 trucks to deliver goods and perform tough jobs on a daily basis,” said John Beering, senior vice president and general manager for Eaton Commercial Vehicle Transmission.
The product is scheduled for release in July.
Eaton said it employed the dual-clutch technology for more efficient acceleration from a stopped position and to optimize shift points to move efficiently to the highest gear. Gear changes are made by swapping engine torque between clutches, with the next gear preselected.
