About a month ago I started having transmission problems. I got the speed sensor, neutral safety switch, and even transmission replaced. That helped for awhile. Then the problem came back worse. Now the car starts fine but stalls out once I have to stop at a stop sign or red light. It revs up hugely immediately after taking off. It sticks in reverse. What else can the problem be? I would have thought the new transmission would fix the problem, but that hasn't been the case.
