Shifting Jump
I have a 87 420SEL, whenever i shift the car it feels like it jumps. whenever theres bumps on the road the interior of the car sounds like the leather to rubbing something. and also when i start up the car to it seem like the car has a hard time starting up. does anyone have any suggestions on what i could do to fix these problems. thanks

When you say shift, do you mean the change of gears? As for jump, do you mean the jolt felt by changing gears? If so, do you experience this when you floor the car? That would be normal since the gears would be changing at a higher rpm. If this is for normal driving, I would suspect this occurs if you are pushing the petal over a quarter of the distance.
As for the interior noise, this seems normal. Not quite sure myself how this is caused, but it could be the shifting of the door panels during bumpy rides?
For the starting up of the car, I would suggest not holding the key on the ingnition too long. I would turn it in < 1 second bursts. If it doesn't start the first time, keep on doing it until it starts. I don't know if this will work for you, but I use this technique myself and starting the car is no problem. Seemed to have worked with an abused '86 560SEL I drove for about a week or two as well as a '95 SL600 that seem to take some time to start (if starting with one ignition key turn, it would take about 3 seconds).

pcviewer,
thanks for the reply, when i say shift the gears i shift it at a complete stop(not moving at all).
maybe the interior noise is the the door panels. know anyone way i could fix it?
thanks for the advice on starting the car! i be sure to try it the next time i drive the car.
THANKS

When you shift gears, you would shift from "D" to "R", and the car jumps or jolts? It is a pretty hard jump/jolt? If this is so, I could only see this happening for the shifts from D to R and vice versa. When going into D, the rear feels like it lowers and going to R, the rear feel like it is rasing. If this is so, it should be normal for clearance I think, but should not be harsh.
As for the interior noise, not sure how to fix it but I guess you could try to tighten the screws that are holding the panal together. You could find two screws beneath the arm rests on each door. There are other screws, but the two in the arm rests are the main ones.
As for starting the car, I forgot to mention that in my experiences, when I do this, eventually, it only takes a < 1 second burst to start the car. I have done this to the following cars:
1986 420SEL
1986 560SEL
1987 420SEL - Car I currently drive. No problems starting the car. Use to take < 1 second to start the car before I was the only driver.
1991 500SL
1995 SL600
