Hi folks, I am looking for input from other 1980 w123 300d/td/cd owners on whether this vacuum diagram reflects the reality of how their cars' vacuum lines are connected up.

Background: this discussion began with another thread that concerned my 1980 300td tranny that won't upshift from second. I've had a short crash course in the wonders of the 1980-only, vacuum-control-only transmission.

In any case, I found this 1980 vacuum diagram through a link in a sticky thread here. It's from the Peter Schmid Transmissions site.

As I see it, it does NOT reflect the reality of how the vacuum on my car is currently plumbed. I'd like to get input from others....

Thx
