What Causes an Automatic Transmission to Stall at Idle?

[DelAriel]

An automatic transmission stalling at idle can be caused by the following reasons: 1. Electrical circuit failure: This may occur due to low-voltage power interruption while driving, leading to stalling. In this case, focus on checking the ignition and starter switches, as well as the fuse box. A short circuit in the low-voltage wiring can cause intermittent stalling. Inspect the vehicle's low-voltage wiring. 2. Component failure: Common culprits include the ignition coil, capacitor, and electronic ignition module. The vehicle may start initially but stall after a while, then restart and stall again. 3. Fuel system failure: Possible causes include a damaged fuel pump, ruptured fuel line, clogged carburetor fuel inlet, or an empty fuel tank.
