Kenworth adds UltraShift Plus VAS for medium-duty trucks

May 12, 2015

Kenworth now offers the 10-speed Eaton UltraShift Plus VAS transmission for its T370, T440 and T470 equipped with the 8.9-liter Paccar PX-9 engine.

According to the company, the Eaton UltraShift Plus provides operators of select Kenworth medium duty trucks with an alternative to traditional manual or automatic transmissions while expanding available application use. Recommended for construction, refuse, municipal pickup and delivery and agricultural applications, the Eaton UltraShift Plus incorporates an electronic clutch actuation system that enables quick shifts and clutch engagement, regardless of engine RPM, the company said. 

“The system automatically selects an appropriate start gear and adapts shift decisions based on driving environment,” Kenworth said. “The transmission, which has a maximum torque rating to handle all medium duty engine ratings, provides better control of engine and transmission functions for smooth automated shifting and vehicle launches.”

 The Eaton UltraShift Plus VAS also features Hill Start Aid, creep modes, auto neutral, and engine and clutch over speed protection, Kenworth said.

“Kenworth has an excellent partnership with Eaton, and our medium-duty truck customers will benefit from the performance and value of the Eaton UltraShift PLUS VAS transmission option for the Kenworth T370, T440 and T470,” said Kurt Swihart, marketing director.
