In Newer automatic transmissions, the valves are managed by solenoids. These solenoids are Computer system-managed, Along with the equipment selection determined by a committed transmission Handle device (TCU) or occasionally this function is integrated in to the motor Regulate unit (ECU). Modern-day styles have changed the centrifugal governor with an electronic pace sensor that is definitely applied being an enter into the TCU or ECU. Fashionable transmissions also factor in the quantity of load on an motor at any presented time, which is decided from either the throttle placement or the quantity of consumption manifold vacuum.
