NZScott got it.
Take the VCV off and keep it as it is NLA as I remember.
You may need it if you get a W123 or W126SD, they were used on those auto trans.
Or some one else may be looking for one.
I have seen the VCV`s on 240`s in the yards with manual gear boxes. probably a trans swap and they left it on not knowing what it is or does.
Come to think of it, my 82 240 parts car has one.
