Why do I have a jerky shift in my car?

What causes a car to have a rough idle?
A rough or uneven idle can be an indicator of an engine that is misfiring. The air/fuel mixture is disrupted which can cause the engine to jump up and down. Illuminated check engine light Modern vehicles have many sensors that monitor the vehicle’s performance.

What should the rate of revolutions be on an idle engine?
When you start your engine, and just let it run without pressing on the accelerator or putting it into gear, that is idling. A properly idling engine should be able to maintain a steady but low rate of revolutions, somewhere in the vicinity of 1,000 RPM. Your tachometer needle should be steady and not jumping around.

Different symptoms can have different causes, so specifics and details can help. The tach always reads some multiple of the actual RPM. For example, the tach reads 2000 RPM at idle and the shift lights come on at mid-throttle. Or it reads 250 RPM at idle and 3000 RPM before you hit the rev limiter, and the shift lights never come on.
Why does my car transmission jerk and hesitate?

What causes a car to jerk when shifting gears?
Transmission Fluid Level – A great place to start looking is the transmission fluid. Transmission fluid that is at the wrong fill level will cause the transmission to behave differently. If the fluid gets too low, than the car won’t move at all. See: Low Transmission Fluid Signs
Why does my transmission shake when I shift gears?
One of the most common causes of transmission problems is low transmission fluid. Transmission fluid provides the lubrication between the gears of your transmission as it shifts.
Why does my transmission jolt when I shift from first to second?
Using the wrong transmission fluid can leave your transmission without enough lubrication, which can cause rough shifting and jolting. If you believe the wrong type of transmission fluid has been used, you should have your mechanic flush the transmission and put new fluid in.
What causes a transmission to jerk or hesitate?
