I have a 90 Integra GS...auto transmission. The problem is getting the thing into park. Especially when it's cold, the car won't seem to get out of gear and into park. This then causes the car not to start. Sometimes if I rock the car back and forth, I can feel it slip into park, then it will start with no problems. Recently I felt/heard it slip into park as it was struggling to turn over. Then it started.
Any ideas....solutions?

Thanks
