If I’m in an automatic transmission car on a slight hill and I press the gas just enough to stop myself from rolling back, so I’m not moving, how does the engine not stall?

A lot of good answers here but lemme give a ELI5 version someone gave me once.

In automatic transmission cars, there are 2 big fans. One fan is connected to the engine and one connected to the wheels. The engine turns one of the fans, and it blows on the other fan to turn the wheel. So when you press the gas on a hill, you just turning one fan while keeping the other one still, perfectly doable.

Now it turns out the fan doesn’t blow air but blows super thick liquid like slime. But that’s beyond the point
