ok this started the other day when i put it in reverse and start going back i would hear a screaching sound, i figured it might be my speedo gear cause i think the wrong one is in there (not enough teeth), so i didnt really think much of it cause it would only do it in reverse, then i would start to hear it when i pushed in the clutch to change gears so i brought it home and as i pulled in the driveway with the clutch in it would just screach the whole time the clutch was pushed in, no idea what it could be any ideas???
