Hello!
Recently, there was a vibration in my gear selector at Bentley Continental GT 2004.
When you do a little acceleration and release the gas pedal, the automatic transmission selector starts to vibrate, like a vibrator on a phone.

Vibrates more in manual mode.
If you press the selector as far back as possible from mode D to mode S, but do not switch, the sound almost disappears.

At the same time, the engine and gearbox work smoothly, there is no vibration on the panel or somewhere else.

I signed up for the service, but the wait in my city is several weeks.

What could it be?

 

Selector vibrates, the vibration depends on the speed of movement, but if you press the gas, it disappears.

On the first video there is a moment where I pressed the gas and the vibration disappeared.

In the second video, I just roll and the selector vibrates always.

Good morning,

Vibration diagnosis via forum/internet is challenging. On my BGT a similar vibration was the shifter cable beneath the vehicle touching the black cast transmission support. A slight adjustment pushing it away from the
support sufficiently remedied the condition.

 

Yes, understand.
I was looking for someone who might have a similar problem.

Need remove the gimbal to adjust the shifter cable?

It feels like a vibration is created when the shift cable hits the gimbal.
since the vibration frequency depends on the rpm.

I'm afraid it might get damaged.

I still have not got into the service, because. there are problems with the recording time.

 

The shift cable is flexible. Sometimes the shifter cable position touches the body or frame and transfers the vibration as described. I would not remove anything before moving the cable by hand a couple mm/cm (s). My shifter vibration was quite sudden and noticeable and that's all I did.

 

Did you do it at a service center or do it yourself?
To move it, you need to crawl from below or disassemble the console from above?

 

Nothing to disassemble. I lifted the vehicle and worked from under the car. Moved the shifter cable by hand, took 5 minutes to adjust so it wasn't resonating vibrations from the chassis. You may have another issue however, the method suggested might be the simplest solution.


See the picture above for reference. The exhaust was removed at the time of the photo. There is no need to do anything with the exhaust.

 

Thanks a lot!
I'll try to look at the shift cable as soon as I get a chance.
