Does stalling an automatic transmission in Drive (D) gear harm the car?

[LeHaley]

No impact on the vehicle. Here's relevant information: 1. For automatic transmission vehicles during driving, it's generally impossible to stall the engine in Drive (D) gear. If it occasionally stalls while still in D gear, there's no harm to the car - the only consequence is you can't remove the key unless in Park (P) gear. Simply power on and shift to P gear afterward. 2. Many modern vehicles feature automatic start-stop systems where the engine automatically shuts off when braking for over one second at traffic lights (while remaining in D gear), which is completely normal as the computer handles all background operations. The engine automatically restarts when you press the accelerator again.
