Hi, My car jerks initially at 10MPH and that jerk is pretty much noticble and then the remaining jerks are not that bad at 40 and 60. I took it to the mechanic and they topped off the tranmission fluid and said there is nothing wrong. But i still get that problem. the only thing is the jerk goes away if the engine stays on for more than 30 mins. Please advice.

Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
