A system includes an agricultural vehicle, including an engine; a transmission with multiple gear ratios driven by the engine, and a controller. The controller is configured to receive a requested wheel speed input by an operator, calculate a desired engine speed, command a gear upshift if a current engine speed is more than the desired engine speed and if upshifting will locate the current engine speed closer to the desired engine speed, and command a gear downshift if the current engine speed is less than the desired engine speed and if downshifting will locate the current engine speed closer to the desired engine speed.
