This is a new one to me. I'm no stranger to w123 cars, with many high mileage versions, but my 81 240D is about as pristine a low mileage example as one will find.
Driving it today, I noticed a new phenomena with the auto trans gear selector. The best description I have is the noise when a w123 speedo cable is binding under the dash... That rotating-tapping sound. However I have absolutely proven that this which I encountered is only related to minute differences in the location of the gearshift lever when it is in drive.
Some other observations:
-noise only observed at some speeds
-noise mostly observed when going through speed ranges on deceleration.
-noise absolutely related to slight variations in gear selector location
-absolutely no issue with selection of position
Ive seen discussions of bushings in there that can cause issues. I suppose that could be it. I've never encountered this in any of my other w123 cars, so would appreciate done thoughts as to what may be the cause, and if it is bushings or something else.
Thanks!
