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

It’s because of transmission ratios. When your car is stopped, you want the lowest transmission ratio to go from 0 -> moving so you can have the highest load-pulling capacity. Going from 0 -> moving is actually the hardest thing for your car to do. Once you are already moving, you have inertia helping you out, so you can use the higher transmission ratios (and need less torque to keep things spinning). Moving cars in 2nd, like you’ve tried out, only really works for lighter cars. If you tried to move a bus in 2nd it probably wouldn’t budge haha.
