Abstract: A work machine having a powertrain, an engine, a torque converter operably connected to the engine, a transmission, a selector interface, and a control system. The control system is configured to: receive a machine activation signal from the selector interface indicative of operation of the work machine; receive machine conditions to determine an optimal gear for next pass; and send a gear pass signal to command execution of a directional shift and a speed shift simultaneously when a gear ratio setting of the transmission is indicative of a second gear ratio.
