"Wheel of Fortune" rattle when decelerating\coasting from ~35mph
#17
I removed the console entirely and went for a drive today to check some things out.
1. The noise is much louder without the console - it does a pretty amazing job of making the cabin quieter.
2. The noise sounds like it is coming from or possibly through the shifter mechanism.
3. Shifting into neutral and removing the load from the driveline while the noise is in progress makes no difference to the sound or the sound level.
4. Shifting into manual mode makes no difference to the sound or the sound level.
Upon restoring the console to its proper position (the console and all relevant parts needed to keep it in the car were not present for the drive), the noise temporarily subsided. The quiet lasted about 15 miles, then returned. There is also the same noise on acceleration at almost precisely 18 mph indicated. It is possible to make the noise pretty constantly on a small downgrade if you keep the speed in the right range. I have a short road very near my home that is a small downhill followed by a similar small uphill. I looped it (I am sure if anyone was watching they were thinking I was up to something nefarious) about a dozen times to try to isolate the source, but it really sounds as if it is coming from inside the shifter mechanism. There is no guidance from the factory on disassembling the shifter mechanism. It is a remove and replace only part. As one might guess I am hesitant to disassemble it without a spare on hand to replace it. I found a junkyard part for $220. I have to think about whether I want to gamble on it being the actual cause. The other thing to do is to ensure the bolts connecting the shifter to the transmission are tight and the wear points in the mechanism are not loose (worn bushing, etc.) causing the noise to come up through the shifter itself.

I'll have to give a better listen, but I believe I also have this noise as it's present at the same exact speeds 35-40. I don't think mine is as loud. My car, 2008, had some missing clips under passenger side front door (it holds the rocker panel plastic). I replaced those, but I was thinking my noise was related to a panel that was "flapping" at a particular speed. I'll give a better listen.

Worn bushings, ujoints etc. All the videos in this thread sound exactly like trans NVH.
You're all describing a noise occuring directly above the trans tunnel which is an echo chamber itself.
Remember any noise is simply vibration.
In one video the low speed lugging in high gear is going to generate vibration regardless of how new or tight tolerances are.
Nope.

Sorry, not going to believe this is normal. I bought the car new unlike many members here now. It never made this noise until recently and it is NOT normal. Sure it might be a worn bushing in the shift linkage, or some piece in the shifter mechanism itself showing its age, but when you go 150k miles with nothing, then this pops up, it isn't normal at all.

Forgot to talk to you about this... But I think I have this phenomena when I pull away in the morning..
Throwing in my .02 cents based on age of parts; has anyone replaced the Rear Engine / Trans. Mount that sits right under the center console box undercarriage ???
