Simplified: The governor dumps presssure, when then centrifical force swings the weights out the valve is pushed in blocking off fluid exhaust passages. This causes fluid pressure to "back up" and puts pressure against the shift valves in the valve body and they shuttle against their respective spring pressures thus opening passages for fluid to apply the various clutches and band. You can makes some changes with the governor but with limitations.
Once the gov. valve is 100% in the control action shifts to the valve body.
