I replaced my tranny and diff with low mileage AP1 ones, and replaced the engine, tranny, and diff mounts as well. I now hear that "cards in spokes" sound. It might have been there before the changes, but it is VERY pronounced now. It almost seems that I can feel it (instead of just hear), lol.

I actually installed the mounts in different times, and I THINK I started noticing the sound after I installed the tranny mount.

I thought it was the TCT so I replaced it with Billman's upgraded TCT, but the sound is still there. It is more obvious in lower speeds. I THINK it's relative to the RPM and not MPH.

The sound is NOT THERE in neutral, idle, or when I don't press the throttle. I can only hear it when I hit the throttle. (It's there. See vid.)

Any ideas?

UPDATE:
- It sounds like it's coming from underneath the center console -> transmission
- I can feel it slightly on top of the normal cabin vibrations
- It doesn't sound like it is coming from the engine bay

Any other mods on the vehicle? Exhaust, test pipe, suspension, wheels etc etc? Any chance you can post a video?

 

Stock exhaust.
Stock cat.
Suspension stayed the same, but Bilstein PSS coilovers, ST front sway, AP2 rear sway, strut bar, rear BSK.
Sound was there when I had my CE28s, and its still there with my track wheels.

I'll try to take a video and post it later tonight.

 

Any idea where it's coming from?

 

Loose heat shield? reminds me I need to do mine. Freaking shop left a few bolts off..

 

No, not yet. I'll play with the car today, and provide an update.

I don't have a heatshield on my OEM header if that's what you're referring to.
I'll try to wiggle the battery heatshield and see if it moves around.

Might have an oil cap on top of the transmission.

There is a heat shield around the cat. check that to make sure it's not touching anything.
