This weekend I finished my car and planned on taking it to the muffler shop. After starting the car and backing out of the garage I shut the car off to check the tranny fluid. It was low so I added some more. I went to start the car and heard a lound grinding noise and the engine rocked violently. My buddy told me that maybe we overfilled the tranny. We decided to push the car back in the garage but it would not shift out to park. So we drainded some fluid where it was at. After that the car would shift out of park and I managed to get it started but the starter or ring gear sounded awful. Is it possible to over fill your tranny and have this happen?
