Reasons for Automatic Transmission Stalling at Startup?
1 Answers
Common reasons for automatic transmission vehicles stalling include: 1. Electrical circuit failure, possibly due to low-voltage power loss or quenching during driving. In this case, primarily check the ignition switch, starter switch, and fuse box. Stalling caused by a short circuit in the low-voltage circuit results in intermittent stalling; inspect the vehicle's low-voltage circuit. 2. Equipment failure, typically involving the ignition coil, capacitor, or electronic ignition module. The vehicle may start initially but stall after some time, then restart only to stall again. 3. Fuel system failure, such as a damaged fuel pump, ruptured pipeline, clogged carburetor inlet, or empty fuel tank. Although the car can be restarted under these conditions, it is difficult. Issues with the ignition system or the engine's overheat anti-knock system can also cause stalling. Below are the steps to handle stalling: 1. For an automatic transmission vehicle stalling, immediately turn on the hazard lights to alert following vehicles. 2. Apply the brakes to stop the vehicle as quickly as possible, then turn the key to restart. Stalling may be due to a faulty or dirty engine speed sensor, problems with the idle control program in the engine's electronic control unit, or fuel quality issues that could also lead to stalling.
