These solenoids are Computer system-controlled, Together with the gear variety made the decision by a devoted transmission Management device (TCU) or occasionally this operate is built-in into the motor Manage unit (ECU). Modern-day styles have replaced the centrifugal governor by having an electronic velocity sensor that may be made use of being an input into the TCU or ECU. Modern day transmissions also Think about the quantity of load on an motor at any presented time, which is determined from both the throttle situation or the amount of consumption manifold vacuum.
