What keeps an automatic transmission from stalling?
The reason that an automatic doesn’t stall out while “in gear” and at a stop, while a manual transmission does, is that automatic transmissions use a hydraulic torque converter to connect the engine to the transmission, while manual transmissions use a friction clutch.
Should an automatic car stall?
Can an automatic car stall? Yes, an automatic car can still stall. An automatic car uses a torque converter to manage the transmission fluid which keeps your engine running when you are at a standstill and if your torque converter fails then the engine will most likely stall.
Why is my car stalling at red lights?
If your car stalls out at red lights, it means that your engine suddenly can’t control the idle. When your engine loses the ability to control the idle, this could be due to several factors, including the following: A malfunctioning or dirty mass air flow sensor.
Why does my car stall when I stop?
If your car stalls when stopped, it could be air-related, fuel-related, or ignition-related. Incorrect air readings could result in your car stalling. It will usually fire right back up though. If there’s not enough fuel pressure from the fuel pump or from a blocked fuel filter, your car might stall at idle.
Can a dirty air filter cause a car to stall?

Why does my car suddenly die while driving?
Malfunctioning ignition switch. When the ignition switch is worn down, there can be a loss of power to the engine because of vibration like hitting a rough patch of road. This loss of power causes the engine of the car to die while driving.

It sounds like you are losing fuel pressure when the car sits. Check fuel pump pressure and then pay attention to fuel pressure drop off. The system should hold pressure for a while. If you find it drop of quickly, you may have a leak, a weak fuel pump, or a leaking injector.
