I am getting this squeaking from the car. It does it in 1st & 2nd if I am low in the rpm's and I take the foot off the gass and it does it in reverse the most. As I am backing up it does it al the time and stops if I push in the clucth. I could still be rolling and when I hit the clucth it stops and when I let it ous it starts again. What could thes be?
