A method of controlling driveshaft speed includes generating an overspeed protection action signal if an engine speed limit and a requested transmission gear ratio correspond to a driveshaft overspeed condition. An operating method for a machine (10) includes disengaging a relatively higher transmission (14) gear, and inhibiting re-engagement of the higher transmission gear responsive to an overspeed protection action signal. An electronic controller (30, 40) for the machine (10) is configured to generate an overspeed protection action signal responsive to an engine speed limit and requested transmission gear ratio. |
