Sterling Truck Corp. announced availability of the Eaton Fuller UltraShift Highway Value (HV) 6-speed transmission as an option for all Sterling Acterra trucks.

A fully automated transmission system for Class 6-7 vehicles, the UltraShift HV combines the reliability and durability of a manual Fuller 6-speed transmission with automated shifting logic. The transmission is suited for pickup and delivery, service, utility and recovery applications, and is capable of handling torque capabilities up to 660 pounds per foot and loads up to 33,000 pounds gross vehicle weight.

The transmission's Hill Assist feature automatically minimizes rollback and roll-forward on grades ranging from 3 percent to 10 percent while the driver transitions from brake pedal to throttle.

In a study conducted by an independent, third party firm, the UltraShift HV results in urban fuel economy that is 6 percent to 19 percent more efficient than the leading conventional automatic transmission, depending on the duty cycle, according to the company.

The transmission also offers life-cycle cost savings, with no scheduled maintenance for 500,000 miles, including filter and lube changes, and doesn't require an external transmission cooler.
