harsh shift into "D" and "R"
 

I have a problem with harsh engagement when selecting "D" or "R"
It seems like my iddle rpm is too high when changing into D and R and the car has some recoil....
other than that it shifts fine...
I know that my front flex disc is bad but is that the problem?
Anybody had simmilar problem? what did work ?
thanks

In general Bad Flex disc will definately be a major factor. Bad engine /differential mount also are found to be the cause for hard 'D' and 'R' engagement.
I had same problem with my 87 420SEL, I have resolved the hard "R" issue by replacing engine and differential mounts but still have the hard "D" shift from "P". Still working on it, I have changed quite a few parts to eliminate the problem, eg engine mount, differntial mount, subframe bussings etc.

What is your rpm reading at idle? mine is 700--800 at idle.

Keep us posted.
Thanks
