Well, an answer for this question is going to be a shot in the dark. But I could use any experience you guys have on this.

I have a rattle coming from somewhere around my motor. It sounds more like the drivers side area. Now, I got my transmission rebuilt about 3/4 a year ago. It just started to make this rattle sound this winter. I have never heard my car do it before so I thought transmission. Took it back for warranty and they swear its not the tranny but its coming from the motor somewhere.

Now this rattle doesn't have a normal tendancy. It just comes and goes randomly. It seems worst in the mornings or when the motor is cold. I cannot hear it when the car is driving and it does not make the noise when the motor is reved up. Only at idle.

So, maybe the exhaust is loose somewhere. It is really hard to pinpoint. I understand you guys haven't heard it and that would help, but I thought maybe some speculation on to what you guys might think could help me. Thank you!!

Heat sheild maybe??

It sounds like sheet metal or something close when its cold or you rev when parked. I think its a baffle in the cat? I have headers so no heat shield and it still makes that noise. Im pulling this out of my ass but look at your cat. Mine has done the same thing since I got my car way back in 98.

Is this possible the infamous rattling from the tranny problem that many of us suffer from?

I think that XtremeRS diagnosed it as a the throw-out bearing vibrating a bit under idle when the clutch is not depressed. I had this issue on my car as well, and it normally sounded MUCH WORSE in the winter, and bearable in the summer upon warmup of the car.

Some people say replace the TO bearing, but when I installed my built engine and new clutch w/ to bearing, I STILL had the same problem.

Check to see if the noise goes away when the clutch is pressed in. If it is constant, it could be a heat shield or something with the exhaust, but if it stops when the clutch is in, it is something with the transmission.
