well before you run any tests, is your CEL light on or is your S light blinking? Since this is tranny related, look for your blinking S light. Then, jump the connector behind the passenger side kick panel while the key is in the car and turned to the ACC or whatever is it...(the position where all your dash light come on but the car isn't started) and look for your S light or your CEL to blink.

Also, use a search next time. This has been covered a zillion times.
