How to Bump-Start a Car with an Automatic Transmission
Before attempting to bump-start an automatic transmission car, ensure that the car’s battery is completely dead and the key is in the “off” position. Additionally, check if the parking brake is engaged and the transmission is in neutral.

1. Find a Slope
Locate a gentle slope that is long enough for the car to gain sufficient momentum. The slope should not be too steep, as this can make the process more difficult and potentially dangerous.

2. Have a Helper
You will need a helper to push the car. Instruct them to stand at the rear of the vehicle and apply even pressure to the bumper.

3. Turn the Ignition On
Once the car is on the slope, turn the ignition key to the “on” position. This will activate the car’s electrical system but will not start the engine.

4. Start Pushing
Instruct your helper to start pushing the car down the slope. As the car gains momentum, have them increase their pushing force.

5. Release the Brake
As the car begins to roll down the slope, gently release the parking brake. This will allow the wheels to turn freely.

6. Shift to Neutral
Once the car has gained enough speed, quickly shift the transmission to “neutral” to disengage the engine from the wheels.

7. Turn the Engine On
Immediately after shifting to neutral, try to start the engine by turning the key to the “start” position. If the engine starts, keep your foot on the brake to prevent the car from rolling backwards.

* If the engine does not start on the first attempt, repeat steps 4-7.
* Do not hold the starter motor for more than 10 seconds at a time, as this can damage the starter.
* If the car does not start after several attempts, there may be an underlying issue that requires professional attention.

Safety Precautions:

* Ensure that the parking brake is fully engaged before pushing the car.
* Do not stand behind the car while it is being pushed.
* Be aware of your surroundings and ensure it is safe to bump-start the car.
* If the car has a malfunctioning ignition switch, do not attempt to bump-start it.
* Do not attempt to bump-start a car with a damaged or worn-out timing belt or chain.


Bump-starting a car with an automatic transmission can be a useful skill in emergencies. However, it is important to follow the steps carefully and take necessary safety precautions. If you are uncomfortable or uncertain about any of the steps involved, it is always advisable to seek professional assistance.
