Classification: CPC F  B | IPC B  F

Claim 16:
17. A method of operating a transmission of a vehicle, the method comprising:
receiving, by a controller of a control system of the vehicle, input provided by a first input device of the control system that is indicative of a desired enablement of a boost mode of operation of the transmission;
receiving, by the controller, input provided by a second input device of the control system that is indicative of a desired application of one or more output torque limits at an output shaft of the transmission in the boost mode of operation;
receiving, by the controller, input from a sensor of the control system that is indicative of a grade of a surface on which the vehicle is positioned;
determining, by the controller, a calculated grade of the surface based at least partially on the input from the sensor;
determining, by the controller, whether the calculated grade of the surface exceeds a grade threshold; and
boosting, by the controller and in the boost mode of operation, one or more output torque limits applied at the output shaft of the transmission in use thereof from one or more baseline output torque limit values to one or more boosted output torque limit values in response to (i) receiving the input from the first input device, (ii) receiving the input from the second input device, and (iii) the determination that the calculated grade of the surface exceeds the grade threshold.
