Hi, your transmission definitely could be going out. You could flush it and put in nice fluid. Check the cable and the sensors. If you have larger wheels or rims that would be a factor in it going out sooner. Also if you drove it hard it most likely would be going out right about now. Be careful though it could at this point just completely go out and you will be stuck somewhere. Look for used transmissions, that car if its rear wheel drive will be easy to drop it and replace it.

Flushing your transmission will actually do more harm than good. Sure, it stirs up everything so that you can pull out the contaminants, but stirring up the debris will clog the valve body and can damage the filter. The best thing to do, if you are looking at changing the transmission fluid is to drop the pan and drain it, then you can replace the filter too and then put a new gasket on there and refill it.
