hey guys. i need some help on this one.

today my tranny feels like its not kicking into gear correctly. it will say "ED" on the dash but the car just feels like it has no power. Not wanting to move or antyhing. It just rolls foreward slowly then the tranny will kick into gear and feel fine. I tested it out in my friends driveway and when I put it in neutral the car actually started backing up. any ideas?

im thinking my valve body is sticking or worse...

basically what im saying is whenever i put the car in drive my car will just rev but move VERY slowly when accelerating from a stop. The after a few seconds it will kick into gear then drive ok. just when i get my style 19s today this **** happens. ugh. someone wanna donate a 6-speed to a poor kid?
