My car won't go past 30 MPH
So to start out, my car one day started to shake (very noticeable, like a jerk) when I would stop at a light or something similar, sometimes even turning off when I was stopped. This would not happen to much, maybe once a week. A few weeks after that I was driving home and could not get past 30 mph hitting about 5000 rpms. I then let my car sit for a few days, and tried driving it again. This time it was driving a little better but the car would do one big jerk when it was shifting to the next gear and the shaking/ car turning off when stopped. After a day or two the car was then again unable to get past 30 MPH. I changed out the transmission fluid and filter and it still wont get past the 30mph problem and the car shaking when idle.
