[W126 Coupe] Transmission "Clunk" - But only when selecting Reverse Gear

[Joseph Schumann]

HI Mike:

Have you checked your idle speed....almost sounds like your idle is too high.

I’ve had the trans fluid changed at recommended intervals.   But on selecting reverse gear there is a big clunk and the car initially jolts backwards, sometimes quite violently, with or without the brake pedal pressed.
   
  I’ve searched the archives and can’t see anything specific to reverse gear.  Does anyone know if there is an adjustment or anything to remedy this ?
   
  I’d not want to do anything that may affect the forward gears as they are currently very smooth, but appreciate any help if anyone else has had this.
   
  Cheers,
  Mike
