Abstract
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 includes disengaging a relatively higher transmission gear, and inhibiting re-engagement of the higher transmission gear responsive to an overspeed protection action signal. An electronic controller for the machine is configured to generate an overspeed protection action signal responsive to an engine speed limit and requested transmission gear ratio.
