[MBZ] vacuum amplifier w124 vs w210

[Karl Wittnebel via Mercedes]

Anybody know if the older vacuum amplifier/blue from w124 diesels functions
the same as the later one from the W210 000-545-04-27? Looks like the
earlier one has four hoses, the later one has two and vents to atmosphere.
They all appear to modulate the vacuum to the automatic transmission, to
reduce shift harshness at low power, using boost as a signal. More boost =
crisper shifts. The later one is called a pressure valve and seems to
control intake flaps also.

I need to soften the low power shifts on the 606/722.317 combo. New
injection pump has no modulator on the side; they all run manuals over
there.

board has a bad chip or something. I'm thinking I'd rather build a new one
from scratch to avoid all the bloatware that comes iwth a new PC.
Any recommendations for hardware these days? I haven't bought such since
mid 2000's.

[MBZ] Vacuum amplifier

[Eric Anderton]

On my 85 300D T recently when the engine is to temperature the
transmission has started shifting like it has a lack of vacuum. It
goes from really nice responsive smooth shifting to real clunky
sluggish shifts. I have hooked up my mity vac and the modulator on the
transmission holds vacuum. The blue amplifier that the modular runs
off of however does not. What are some things I could look at to
narrow this down a little? I really do not seem to have a vac leak.
Can the blue amplifier go bad? how would I test this?
Many Thanks.
