hey everyone I am hoping someone might be able to tell me what the noise might be when I am shifting 6 speed mostly 1 gear to 3rd some time in 4th mostly all around 3500 rpm or higher there is a clank noise in between shifts I got under the car and check to see if anything might loose a heat shield maybe but everything seemed to be pretty snug it sounds like its coming from the passenger side I just cant figure out where it might be coming from
