I was driving home last night and I gave it a little gas to pull her in the driveway but nothing happend! The car rolled backwards. Put it into Reverse still nothing happend, Turned the car off and and on still nothing. Finally I put it back in D and put the pedal to the floor and it sounded like something klanked into place and I was able to give it some gas again. Anyone have any idea what this could be? It basically felt like the car was stuck in neutral.
