So this past week I noticed this awesome noise I'm getting at idle when I first start the car. I can hear it while driving but it's extremely faint. It doesn't get faster so I know it's nothing in the transmission (at least I'm praying). It sounds like metal vibrating or something similar.

Here is a shitty cell video but it can be clearly heard:

I just put mine on the lift due to a strange noise and found it was my cut-out flap vibrating! Makes a hell of a noise at idle.

Well I don't have one of those lol. I'm wondering if this could be also the cause of the vibration I've been having at 70+mph in my drive line.

if it was motor related, wouldnt it increase with rpm?

JohnnyBz28

iTrader: (12)

Yup and it doesn't.

SSickLS1SS

so i highly doubt its coming from the engine, its prob something that just rattled loose somewhere in your interior

Nah it's definitely something in the drivetrain. I can hear it when I try to stick my head under the car lol

New video hopefully it's a a little more clear as to what I'm talking about:

So, it sounds like someone stuffed maracas or a dead rattle snake in your tailpipe?

I don't think its related - but I'd suggest making sure the noise still happens with your HVAC and blower fan off. (Very common this time of year to get leaves in there - which makes weird noises.)

Other than the blower fan, I can't think of anything else that rotates constantly at the same frequency. So, there must be something loose and vibrating, like a heat shield.

Yeah but it's coming from underneath the car near the transmission

Your blower motor is just a foot or so away from the transmission. Its an easy thing to eliminate. After that, I'd look at the cat heat shields next.

Well I can eliminate the cat shields right off the bat since I don't have any cats haha

Thanks I'll check that out

Did you take out the shields and the cats or just the cats?

JohnnyBz28

iTrader: (12)

Pretty sure those have been gone since before I've owned the car.

Apparently the noise is coming from the shifter.......................wtf?

JohnnyBz28

iTrader: (12)

hm could this be due to a worn shifter cup?

Ahhhh - Check the bolts that connect the stick to the shifter. A lot of times the lock washer will wear out, the bolt will back out, and that washer will rattle like crazy. (Then your stick comes disconnected = bad.)

If that's the case, you can use locktite or a better lockwasher to secure the bolts. The locktite made a mess for me - so I went to Nord-lock washers. http://www.nord-lock.com/

Well my buddy said when he pulls up on the shifter it goes away. I wonder if it has something to do with the shifter itself. It's a Pro 5.0.

I posted a thread in the manual trans section since it's technically trans related.
