A hydraulically driven utility vehicle, such as a wheel loader or track loader, can automatically shift between two or more operating speed ranges based on prevailing operating conditions. The default condition may be a low speed range, and the vehicle may shift into a high speed range only if an output speed of the vehicle's hydraulic drive motor exceeds a designated threshold. The designated threshold may, for example, be a designated percentage of maximum speed. The machine may automatically shift back to the lower speed range if the output speed of the hydraulic drive motor drops beneath a second designated threshold that may lower than the first designated threshold. Other operating conditions, such as commanded speed, engine load and engine speed, may also be taken into account when determining whether to auto-shift.
