Finally got a new trans in the gt and am driving it for the first time here since September when the trans went on it. Did an oil change and some up keep the other night, and I noticed something the other day when I'm on the gas, just under normal load it sounds like a rattling noise is coming from the motor. So I popped the hood just now to check on it, and I remember the same noise from over a year ago, but it was coming from the bottom side of the motor then and we ended up putting in new rod bearings and it took care of the problem. This time it seems to be coming from the top of the motor..so I'm clueless..any ideas? I can't win with this damn car
