Abstract
A system and method involves a machine that powertrain including a continuously variable transmission (CVT) and a machine speed sensor to determine a measured machine speed. The machine also includes a controller in communication with the CVT and the speed sensor. The controller may include a table relating the measured machine speed to a plurality of virtual gear ratios associated with the CVT. The controller is configured to determine a calculated virtual gear ratio using the table and, if desired, may display the calculated virtual gear ratio on a visual display.
