Hello, i have been having this trouble with my car for a while. I have taken it to two diferent mechanics and they dont know What is happening. When i come to a stop(at a light or stop sign) when i go to accelerate It will start jerking when i hit 20 km, I'll let go of the accelerater and it will stop. It will start back up at 40 km and again at 60 km after that it's fine. It only does it sometimes but recently it has been happening more and more often.

 

Sounds like a transmission issue.
