I have read many articles on here but all are for 123 and 126's so I am getting confused as to which information is correct for my car (1987 Mercedes 300TD Wagon). I have a rough shift through all gears really and it thump's into them at almost any throttle location.

I am going to examine the vacuum lines this weekend, does anyone have the vacuum line diagram they can share with me?

[Diagram - Page 6 & 7 for 603.69 engine from 87 W124 Turbo Wagon]

I read in this thread this:

" Bad flex disk at tranny -- makes a thump when it shifts, vibrates some. Easy fix."

... but they are talking about a 300TE not a TD, different transmissions?

What other things can I look/test this weekend when I really sit down and diagnose this issue?

Thanks for reading, you guys have been more than helpful with everything I have asked on this forum!
