First things first, have you checked your fluid level? The way your going to want to do that is with the car warm and running, and the trans in drive, put the e-brake on so you don't have to run next to the car. You're checking for both fluid level and to see if it's burned. Ten to one it's fluid. After that you're going to have to get more specific with symptoms.
