Hello Mike,

Sadly, there isn't anything you can do..what you are describing is the
initial signs of a transmission that's on it's way out.  Fortunately, even
if you lose reverse you'll still have your forward gears.  My advice would
be to try to park the car as though you do not have reverse..only using it
when you Need it will help lengthen it's life.

In order to fix the problem the transmission needs to come and re-done.

On my 1988 560SEC the auto transmission (original) works great in forward
gears, with very smooth change-ups.  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
