Automatic transmission occasionally stalls when reversing?

Check the ignition and starter switch as well as the fuse box. Here are the detailed explanations: 1. Circuit failure: This may be due to low-voltage power interruption during driving, causing the engine to stall. At this time, you should mainly check the ignition and starter switch as well as the fuse box. 2. Low-voltage circuit short: Check the low-voltage circuit, which could be a device failure. This issue is usually related to the ignition coil, capacitor, or electronic ignition module. The engine may start initially but stall after a while. 3. Fuel system failure: Possible causes include a damaged fuel pump, ruptured fuel line, clogged carburetor fuel inlet, or an empty fuel tank.

Last time my car stalled while reversing was also due to excessive carbon buildup in the throttle body, which was resolved after cleaning. Automatic transmission vehicles stalling in reverse is indeed rare, but there are usually several possible causes: First, severe engine carbon deposits, especially dirty throttle bodies in older cars affecting idle speed; Second, poor fuel quality leading to clogged fuel injectors and insufficient fuel supply; Third, aging spark plugs or poor ignition coil contact; Fourth, transmission fluid not changed for too long causing abnormal torque converter pressure. I've personally experienced a clogged fuel pump filter screen preventing oil suction during reversing. If this issue occurs, don't panic. First check if the idle speed is stable, then troubleshoot the engine's operating condition. If it happens frequently, it's best to go to a professional repair shop for a comprehensive inspection.

My car is an automatic transmission and I've also experienced stalling while reversing. At first, I thought it was an operation issue. After consulting with mechanics, they suggested focusing on three main points: carbon buildup in the throttle body can affect idle stability, which can usually be resolved by cleaning; loose wiring harnesses in the transmission control module might cause signal interruptions; and a dirty fuel filter could lead to insufficient fuel supply. Additionally, severe vibrations caused by aging engine mount cushions might interfere with the ignition system during reversing. I later discovered that using low-quality gasoline was the culprit in my case, and switching gas stations solved the problem. Occasional occurrences aren't a major concern, but if it happens frequently, prompt inspection and repair are necessary.

I've been driving automatic transmission cars for over a decade, and occasional stalling during reversing is mostly due to carbon buildup. Especially at idle when the engine load is minimal, excessive carbon deposits can easily cause stalling. Additionally, unstable transmission oil pressure, clogged fuel lines, or insufficient battery voltage can all trigger this situation. I remember one summer when I was reversing with the AC on, the compressor suddenly kicked in, increasing the load and causing the engine to stall—later inspection revealed a loose alternator belt. It's advisable to first check the throttle body and mass airflow sensor, then test the fuel pump pressure. Addressing these minor issues promptly should resolve the problem.
