Please help: Annoying noise coming from gear selector
I'm hoping someone can help me out. A little while ago, I noticed a noise coming from my gear selector column. Here's what's happening:
-Sounds like a metal-on-metal rattle
-Only occurs at around 2100-2500 rpms
-I believe the shaft of the gear selector is causing the noise. My reasoning is because the sound gets muffled when I put pressure on the shift knob
Anyone had symptoms like this before?
Can the shaft get loose?
Has anyone heard of parts coming loose inside of that compartment?
I'm clueless, so any help is appreciated. Thanks,
I simply cleaned the pieces and put it back together and pushed the plastic trim in harder and have not heard it rattle since if it starts again I will have to order the small wood trim piece or just get the chrome one. Hope this helps………..best of luck.

722.6 there is no mechanical connection between the trans module and the transmission.You need to isolate the rpm dependent vibration,tires balanced?Worn uneven?

good suggestions. I just switched over to my snow wheels, and the noise still occurs at the same RPM. So I think I have ruled out the tires not being balanced properly.

The Shift Rod Linkage that goes from the SHIFTER to the Transmission
ITS THERE..I have replaced SEVERAL shift rod bushings on the W210s
Its a Easy repair...best when raised on a lift
so onto the possibility of that making the sound,when you shift into manual mode from drive slot it disconnects the shift rod and relays trans position via the module,so with the rod now not in contact the noise if it is the shift rod linkage bushing should not be present.Correct, Mark?

The Shift rod is connected from the Transmission to the Shifter.....
Your question that the possibility of the sound from the shift rod will NOT be in contact is NOT True..as the transmission is shifted P/N/D via the shifter
when its in D its STILL connected via the shift rod..only Upshift/Downshift is done via the contacts IN The Shifter..
Take a look at YOUR car then YOU will Understand how the shifter works..
-But the gearshift lever isn´t hard to remove and dismantle. Might also be something wrong in there.
