you only need to post a question in one place people will see it.

1. Take it to a shop and at least get an estimate and an educated guess as to what might be wrong
2, A transmission flush might not be a bad idea.
3. Have a local auto parts place run a scan if the tranny lite is coming on it may have a code for you.
4. check back here other more experienced may have chimed in by them. Remember this is not a manned board with people waitng around to answer questions in real time.

Good Luck
