My car jerks and surges when moving from a stop at low rpm. Its an automatic, but it acts like a novice driver would with a clutch transmission. It runs fine once the speed is up to 10mph. What's the problem and solution?

My van does this whenever the transmission fluid is slightly low... which is about weekly. (If I planned on keeping this van, I'd get that leak fixed, but that's a separate issue.) I just add about a pint of ATF and I'm fine for a bit. However, I should warn you that this may not be your issue; it is merely what my experiences with one particlar vehicle are.

your cadalidic converter may be cloged that would be my guess o2 sensor or something

Without knowing what you are driving, I can only guess, but it is possible that it isn't a transmission problem at all. A bad throttle position sensor will produce exactly the symptoms you are describing.

I had this problem too. I flushed out the transmission fluid to stop the valves from sticking. It now runs a lot better. This might not be your problem but it's a cheap solution to your problem without having to bring it in somewhere.
