In more recent automatic transmissions, the valves are managed by solenoids.[fifteen] These solenoids are Laptop-controlled, with the gear range made a decision by a devoted transmission control device (TCU) or from time to time this operate is built-in in the engine Command unit (ECU). Modern day designs have replaced the centrifugal governor with an electronic velocity sensor which is employed being an input on the TCU or ECU. Modern transmissions also factor in the quantity of load on an motor at any offered time, which is set from both the throttle situation or the amount of intake manifold vacuum.[15]
Whenever you've spent all of your driving everyday living driving the wheel of an automobile having a handbook transmission, an automatic may appear confusing.
