Why does my car Jerk when I speed up?

This type of car jerk is very common in a manual transmission, especially for those who are just starting to learn how to drive and mostly happens when you are trying to shift from the first to the second gear while you speed up. A stick shift car gets you more involved than an automatic one.

What happens when you shift from 1st gear to 2nd gear?

For example, when shifting from 1st gear to 2nd gear, you need to let the rpms drop to the corresponding gear speed, and then pull out the clutch. If you pull out the clutch before the revs fall to the correct rpm, the engine will buck. If you wait too long and the rpm is too low, the engine will jerk. The same principle applies to down-shifting.
