1983 W123 300D Vibration & Hard Shifts until warmed up
Hi,
I have a 83 300D with 162K miles, that I just bought and had valves aligned, new fuel filters, new transmission filter/fluid. When I start it in the morning it runs very sluggish and slips and slams when shifting. But then on my way to work, after about 15-20 min. at 75mph it has much more pep and the shifing is very good...but still not perfect. Additionally for that first 15-20 min. on the highway, I get vibrations in the seat and steering wheel very much like my wheels need balancing. I have had them balanced though, and if it was a balancing issue it wouldn't go away after 15 min.
I suspect that all this is maybe related, but am not sure where to start looking. Is it possible that the car could have lousy vacuum until after it runs for a while? I guess this could explain the shifting, and maybe the vibration. What is this a symptom of?
I have fallen in love with this old car and if I could get this figured out life would be great!
Thanks for any help...

Check Your motor mounts. They may be bad.That would explaind vibration.
The Transmission sounds like a vacuum leak.
