Chance:Does this car have an automatic transaxle or is does it have a clutch? M problems with answering your question. When you say you have done everything you know to fix that, again I have no idea how much you know. Do you have a repair manual for your car? That would be a good place to start, it would give you ideas what could be wrong and how to fix it. If an auto, I would try the overdrive control switch connetor as something to look at. Could be a bolt or something has come loose, a hose or something like this. But that manual would help you a lot. They are not very costly maybe $20.00 and I like the Haynes the best. Easier to understand and they will walk you through things. Could be if your car is an clutch that your gear is weak, could be a bearing out, spacer not working right well heck your clutch might not be working right either. If you do have a clutch. So get that manual and if you can not find it. Take the car to a shop. Hope this helps and good luck!
