Abstract
A machine has a power train including a prime mover connected to a transmission having two or more selectable gear settings. The machine includes an electronic controller configured to receive and transmit signals indicative of machine parameters. The electronic controller contains computer executable instructions for determining a current value for at least one efficiency metric of the machine at a current gear setting of the transmission. Instructions for determining a first expected value for the efficiency metric at a first alternative gear setting, instructions for comparing the current value with the first expected value to determine an optimal gear setting as between the current gear setting and the first alternative gear setting at least partially based on engine speed, and instructions for indicating a gear shift recommendation and/or performing a gear shift to select the optimal gear setting are executed during operation.
