i have a 99 civic si . and something want in the tranny and im thinking its a throwout bearing ,, i was driveing it and it started getting this weird sound like a rock in a can being shacked but everytime i would push in the clutch it would go away but when i left it out it would make the sound but i was driveing it and the tranny just locked up .. the car starts but the only way it moves is with the clutch in . and its like stuck in gear in the tranny but i can still move the shifer in gears but in in N it shuts off with the clutch out ,, any ideas ?
