As the title says, I know that different shifts mean different gear sizes bein used, but I don’t understand why it makes you unable to start moving the car. I have been able to start a couple of cars on the 2nd shift as an experiment and I understand that I could damage the car and I do it just once for testing purposes but I don’t understand why I cannot do so on other shifts. To clarify, I mean start as in start moving the car and not just turning the car on. Thanks

I think maybe like 1 out of 100 actually answered the question properly without introducing irrelevant info. Whack.
Simply, the transmissions and differential actually multiply the torque of the engine. In first, the transmission might be multiplying the torque by 3x, followed by the diff by 2x. So an engine making 100 power, in first gear would be making 100 x 3 x 2 = 600 power. In second, 100 x 2 x 2, which is 400 power, third being 300 power, etc.
So moving a 1000lbs ball is a lot easier with 600 power, than it would be with 100 power
