As a car owner, you’ve probably experienced the frustration of dealing with a dead car battery. It’s a common problem that can happen to anyone, and it can leave you stranded in the middle of nowhere. But what if you’re driving an automatic transmission car and your battery is low? Can you still start the car? The answer is yes, but it requires some knowledge and the right techniques. In this article, we’ll explore the best ways to start an automatic transmission car with a low battery.
Understanding Car Batteries and Automatic Transmissions
A car battery is responsible for powering the car’s electrical systems, including the starter motor, which is responsible for turning the engine over. In an automatic transmission car, the battery also powers the transmission’s electronic control unit, which regulates the gear shifts. When the battery is low, the car may struggle to start or may not start at all.
Automatic transmissions use a complex system of sensors and solenoids to shift gears. The transmission’s electronic control unit receives signals from the sensors and adjusts the gear shifts accordingly. When the battery is low, the transmission’s computer may not receive the necessary signals, making it difficult to start the car.
Why Can’t You Just Jump-Start an Automatic Transmission Car?
Jump-starting an automatic transmission car is not as simple as jump-starting a manual transmission car. In a manual transmission car, the starter motor is responsible for turning the engine over, and a jump-start can bypass the starter motor and get the engine running. However, in an automatic transmission car, the starter motor is only responsible for turning the engine over, and the transmission’s electronic control unit is responsible for shifting gears.
When you jump-start an automatic transmission car, you’re not just bypassing the starter motor, you’re also bypassing the transmission’s electronic control unit. This can cause the transmission to malfunction, leading to costly repairs. Additionally, jump-starting an automatic transmission car can also damage the battery, the starter motor, and the transmission’s electronic control unit.
How to Start an Automatic Transmission Car with a Low Battery
So, how do you start an automatic transmission car with a low battery? The good news is that there are several methods you can use to get the car started. Here are a few:
Method 1: Using a Boost Pack
A boost pack is a portable battery pack that can provide a temporary boost of power to get your car started. Boost packs are designed specifically for jump-starting automatic transmission cars and can be purchased at most auto parts stores. (See Also: How to Tap Power from Car Battery? Safely)
To use a boost pack, follow these steps:
- Connect the positive (red) cable from the boost pack to the positive terminal of the dead battery.
- Connect the negative (black) cable from the boost pack to a metal surface on the car, such as the frame or a bolt.
- Start the car and let it run for a few minutes to recharge the dead battery.
- Once the car is started, disconnect the cables from the boost pack and the dead battery.
Method 2: Using a Portable Charger
A portable charger is a device that can charge your car’s battery on the go. Portable chargers are designed to be compact and lightweight, making them easy to carry with you.
To use a portable charger, follow these steps:
- Connect the portable charger to the dead battery.
- Start the car and let it run for a few minutes to recharge the dead battery.
- Once the car is started, disconnect the portable charger from the dead battery.
Method 3: Using a Jump-Start Kit with an Automatic Transmission Adapter
A jump-start kit with an automatic transmission adapter is a specialized kit that is designed specifically for jump-starting automatic transmission cars. These kits include a special adapter that connects to the transmission’s electronic control unit and allows the car to start without damaging the transmission.

- Connect the positive (red) cable from the jump-start kit to the positive terminal of the dead battery.
- Connect the negative (black) cable from the jump-start kit to a metal surface on the car, such as the frame or a bolt.
- Start the car and let it run for a few minutes to recharge the dead battery.
- Once the car is started, disconnect the cables from the jump-start kit and the dead battery.
Precautions to Take When Starting an Automatic Transmission Car with a Low Battery
When starting an automatic transmission car with a low battery, there are several precautions you should take to avoid damaging the car’s electrical system:
- Make sure the car is in park or neutral before attempting to start it.
- Use a boost pack or portable charger specifically designed for jump-starting automatic transmission cars.
- Avoid using a regular jump-start kit, as it can damage the transmission’s electronic control unit.
- Avoid overcharging the dead battery, as it can cause damage to the battery and the car’s electrical system.
Conclusion
Starting an automatic transmission car with a low battery requires some knowledge and the right techniques. By using a boost pack, portable charger, or jump-start kit with an automatic transmission adapter, you can get your car started without damaging the transmission’s electronic control unit. Remember to take precautions when starting an automatic transmission car with a low battery, and always follow the manufacturer’s instructions for any jump-starting equipment you use.
