When we first got a rel cold evening about a month ago... I started my car the next morning and it sount like a marching band. I have a 98 Eagle talon with the 420a. I thought it was coming from under the valve cover, but further investigating, it is coming from the tranny. It only does it in the mornings and quits after it warms up for a little bit. Any suggestions??? please leave any advice. ( noise sound like a small hammer smackin around in the bellhouseing) Thanx.
