A method comprising the steps of: in response to determining that a gear ratio shift is to be initiated while a vehicle is in motion reducing pressure exerted between a first rotating body and a second rotating body, wherein the first rotating body is rotatably driven by a drive mechanism, and wherein the second rotating body is caused to spin due to friction between it and the first rotating body and comprises part of a linkage for transferring torque to an output portion for propelling the vehicle; implementing a gear ratio shift in a gear arrangement of the linkage; and restoring the pressure exerted between the first rotating body and the second rotating body. |
