Eaton UltraShift PLUS Now Available in Western Star Trucks

FORT MILL, S.C. — Western Star Truck Sales, Inc. today announced the availability of the Eaton UltraShift® PLUS automated transmission for all Detroit Diesel DD13®-equipped Western Star® 4900 day-cab configuration truck models.

The UltraShift PLUS – available in six transmission models – suits the needs of both on-highway and vocational applications, and features maximum power capacity, superior acceleration and low-speed maneuverability.

Featuring a fully automated design, the UltraShift PLUS uses an Electronic Clutch Actuator to engage and disengage the clutch, resulting in faster shifting, smoother engagement and improved maneuverability. The intelligent shift selection software employs grade sensing, weight computation and driver throttle commands to make shift decisions.

In addition, a Hill Start Aid prevents roll-back on steep grades, while maximum engine braking also adds greater traction without the weight and cost of a retarder.

“The Eaton UltraShift PLUS not only increases efficiency and performance, but also allows our customers the ability to tailor their transmission to meet the unique needs of any on-highway or vocational application,” said Ann Demitruk, director of marketing, Western Star.

Eaton UltraShift PLUS is now available to order for all DD13-equipped Western Star 4900 day-cab trucks, and will be available for DD13 and Cummins ISL-equipped Western Star 4700 trucks in January 2012.
