My 94 Caravan 4spd auto makes a kind of metal rattling noise in the front, somewhere around engine. It sounds like a bell ringing. it's hard to pinepoint its source. I can hear it at idle in Drive or Reverse. it's loud when I back out of garage, or stop at red light on a quite street. No noise at all in P or N. And it can hardly be heard when running on road. I feel the transmission works ok. Advise please. If not a big problem, can I just leave it as is? Thanks! Simon
