In more recent automatic transmissions, the valves are controlled by solenoids.[15] These solenoids are computer-managed, Together with the gear range determined by a devoted transmission Management device (TCU) or occasionally this purpose is built-in into the engine Manage unit (ECU). Modern designs have changed the centrifugal governor by having an electronic velocity sensor that is certainly applied being an input into the TCU or ECU. Modern-day transmissions also Consider the quantity of load on an engine at any supplied time, which is decided from both the throttle placement or the amount of ingestion manifold vacuum.[fifteen]
The first DCT to reach manufacturing was the Easidrive automatic transmission launched on the 1961 Hillman Minx mid-sizing car.
