A method, system, and computing system for governing a speed of a vehicle equipped with a torque convertor includes determining 316, by a controller, that an enable condition is present; determining 304, by the controller, an effort request for a turbine of the torque convertor based on a target speed for the vehicle, the effort request indicative of a change in turbine output power relative to the target speed for the vehicle; determining 308, by the controller, a target speed for an engine of the vehicle based on the effort request and on a relationship between the speed of the engine and the speed of the input shaft of the transmission of the vehicle; and commanding 318, by the controller, a change in the speed of the engine based on the determined target speed for the engine.
