It's the original and it sounds like somebody shaking a rock inside a big coffee can. It's worse at idle, goes away when I increase the rpm, does it when the car coasts or is accelerating and goes away at constant speed. And Oh it did it going over a real bumpy road. It's been doing it for about a week now. I was even wondering if we dropped an nut or washer into the downtube while it was opened up when we put the motor in. Under the car I can't tell whether it's the transmission or the cat but my transmission guy says there isn't anything in the AOD that will sound and act like that. I did notice a decrease in power once when I accelerated hard. Could it be that as it disintegrates it's plugging itself up? Anybody had these symptoms who could verify my suspicions?
