What does it mean for an automatic car to start in reverse?

Normal starting of the engine means that the engine is driven by an electric starting motor, and then the engine transmits power to the automobile transmission system to make the automobile run normally. The reverse starting of the engine is just the opposite. By pushing the car, the wheels drive the transmission system of the car to rotate, and the transmission system drives the engine to rotate, so that the engine can be started through reverse power transmission. Often, when the battery power is insufficient or there is a problem with the starting motor system, the engine is temporarily started by reverse dragging. Only manual gear can start the engine by reverse towing, and automatic gear cannot be started by reverse towing. The method is to turn the car key to "ON", put it in third gear, step on the clutch and let people push the car. When there is a certain speed, the clutch is suddenly released, and the engine will start with a bang under the drive of the automobile transmission system. Press the clutch quickly at this time, and the engine will start successfully.
