1. A method for operating a vehicle, comprising:
simulating gear shifting of a step gear ratio transmission in a powertrain that includes a continuously variable transmission and that does not include stepped gear ratios;
adjusting a propulsive effort request to change from a first value to a second value via a plurality of incremental changes while a propulsive effort pedal position is substantially constant in response to the simulated gear shifting; and
comparing the propulsive effort request to a second propulsive effort request, the second propulsive effort request based on the propulsive effort pedal position and vehicle speed.
