Eaton announced Monday the company a re-calibration of its lineup of UltraShiftPLUS and Fuller Advantage automated manual transmissions to allow for quicker shifts on grades.

A new Aggressive Performance calibration is a software feature aimed at helping vocational fleets operating on construction sites.

Eaton’s Global Product Strategy Manager for Vocational and Performance Transmissions Chris Nielsen estimates the quicker shift times are about 200 to 300 milliseconds faster, allowing the engine to come in at higher RPMs resulting in powerful grade climbs.

Better start gear selection and improved offset have also been added to provide a stronger launch for ultimate control in challenging terrain.

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