How to Start an Automatic Transmission Car When the Battery is Dead?
2 Answers
When an automatic transmission car runs out of battery, the only ways to start it are by using an external power source or replacing the battery. The external power source can be obtained by jump-starting from another functional vehicle or by using an emergency jump starter. Due to the presence of a torque converter in automatic transmission cars, the transmission and engine are not rigidly connected. Therefore, push-starting (bump-starting) is not an option when the battery is dead, as it may damage the transmission. While driving an automatic transmission car, the driver only needs to control the accelerator pedal. The onboard computer analyzes signals from sensors, such as engine throttle opening and vehicle speed, to automatically control gear shifting or engage different gear positions.
Last time my automatic transmission car ran out of battery, I quickly asked a friend for help with a jump start: first, he drove his car over and kept the engine running, then we took out the jumper cables, connecting the red wire to the positive terminal of my battery (usually marked with a + sign) and the black wire to the negative terminal or a metal part of the car body. After starting his car, we waited a few minutes for the current to stabilize before I tried to start mine, and it worked on the first attempt. Remember, you can't push-start an automatic transmission car as it can damage the gearbox. I usually keep a portable jump starter in my car just in case. The main reasons for a dead battery are aging or forgetting to turn off the lights, so it's recommended to check the battery life every six months and avoid using electrical devices after turning off the engine.
