My 1988 560SEL shifts so hard when I shift into reverse from Neutral it feels like the rear end is going to tear out.
shifting into a foward gear from NEUTRAL is harsh but not as severe.
It is a 1988 560 SEL with 120,000 miles fluids and filter been changed 10k miles ago. I really need to get to bottom of this before i tear out the rear end. It shifts smooth after it is in drive it's just from going from neutral into gear. Anyone have a clue what this may be. I had 2 mechanics look at it with no success.

Thank You,
Doug W.
