Eaton has created a new Aggressive Performance calibration for the company’s lineup of UltraShift Plus and Fuller Advantage automated manual transmissions aimed at vocational fleets.

The new software feature will help vocational fleets with quicker shift times to improve performance on steep grade climbs by allowing the engine to come in at higher RPMs. Better start gear selection and improved offset have also been added to provide a stronger launch, improving control in challenging terrain.

Compared to the previous Performance calibration, the new Aggressive Performance calibration improves acceleration by up to 2.9 seconds faster to 25 miles per hour and up to 5.4 seconds faster to 55 miles per hour, according to Eaton. The new shift improvements have also resulted in better deceleration rates with raised downshift points and improved skip shifting on level ground.

“Fleets have been asking us for better performance on grades and quicker acceleration,” said Chris Nielsen, manager, global product strategy, vocational and performance transmissions, Eaton Vehicle Group. “Eaton values customer feedback whenever it comes to improving our products, and we have responded with the new Aggressive Performance calibration that is ideal for fleets that are more performance-minded.”
