w123 1981 240D auto box tuning and vacuum system

My 240D auto box flares (over revs) between changes and the car is pretty slow.
I need to check out the vacuum system but I cannot find a diagram which resembles mine - anyone got one?
I know I need to look at the VCV and modulator. BTW, the car has 75k miles from new.
If you look at the attached photo, you can see that the VCV cannot be removed and the only adjustment is via the two bolts in slots. Most posts talk about removing the VCV but I simply can't. Any ideas or is the adjustment done by turning the housing?
thanks - I am quite sure this is simpler than I think. From what I can see the VCV has one vacuum pipe going in with full vacuum and another coming out and these both go to the switchover valve which than has one going to to the modulator - simple. Am I right on this?
