I really don't understand this. My car was driving fine, I came from a stop light, shifted through all the gears driving normally then I came to the next light and it wouldn't go in any gear. It will physically go in gear but it won't go anywhere. It doesn't grind or anything, it just won't move. I'm quite frustrated and confused. Any help would be great. Thanks in advance.

Auto or manual first off?

Does the car stall if you come off the clutch?
