As an automotive expert with years of experience in the field, I can tell you that the process of pushing an automatic car to start it with a dead battery is not as straightforward as it is with a manual transmission vehicle. The reason for this lies in the fundamental differences between the two types of transmissions.
In a manual car, you can push the vehicle to a certain speed and then manually engage the clutch, which will allow the engine to start turning and potentially start the engine. This is because the clutch can be disengaged, allowing the wheels to spin the engine without the transmission engaging.
However, in an automatic car, the transmission is designed to prevent the car from rolling unless the brake pedal is pressed. This is a safety feature to prevent the car from moving when it is not in gear. Additionally, the clutch in an automatic transmission, known as a torque converter, is not manually disengageable like in a manual transmission. The torque converter is designed to multiply the engine's torque when starting from a stop, but it requires the engine to be running to function properly.
When the battery is dead, the engine won't start because there won't be enough electrical power to turn the starter motor and crank the engine over. Without the engine running, the torque converter cannot engage, and the transmission will not allow the car to move.
So, to address the question, you cannot push start an automatic car with a dead battery in the traditional sense. The vehicle needs to be jump-started using jumper cables or a portable jump starter. Here are the steps you can take if you find yourself with a dead battery in an automatic car:
1. Ensure Safety: First and foremost, make sure the vehicle is in a safe location where it will not pose a risk to traffic or pedestrians.
2. Prepare for Jump-Starting: Gather your jump start cables and another vehicle with a working battery. It's also a good idea to have a set of jump start cables in your trunk for such situations.
3. Attach the Cables: Connect the red clamp of the jumper cable to the positive (+) terminal of the dead battery, and the other end to the positive terminal of the working battery. Then, attach the black clamp to the negative (-) terminal of the working battery and the other end to an unpainted metal part of the car's engine block away from the battery to avoid a short circuit.
4. Start the Working Car: Start the engine of the vehicle with the working battery and let it run for a few minutes to charge the dead battery.
5. Start the Dead Battery Car: Attempt to start the car with the dead battery. If it starts, let it run for a while to ensure the battery charges sufficiently.
6. Remove the Cables: Once the car with the dead battery is running, carefully remove the jumper cables in the reverse order that they were attached.
7.
Check the Battery: After jump-starting, it's important to have the battery checked by a professional to determine if it needs replacement or if there are any other underlying issues.
8.
Consider a Road Assistance Membership: As a preventative measure, signing up for a road assistance service can provide peace of mind, knowing that help is just a phone call away if your battery dies.
In conclusion, while it's not possible to push start an automatic car with a dead battery, being prepared with the right tools and knowledge can help you get back on the road quickly and safely.

Either the automatic gearbox prevents rolling the car at all or there is an open clutch which cannot be closed manually. So if you want to be prepared for your automatic car not starting because of a dead battery, put a jump start cable in your trunk and/or sign a membership with a road assistance organisation.
