Chances are there is a problem with a shift solenoid or the control module. WHat I need you to do is have the computer scanned. If the check engine light has been on, there should be a trouble code stored in the computer. Take the car to a nationally recognized parts store and have them scan it. Most will do it for free.
Ask then what code or codes they found and let me know what they tell you.
