Wife complaints new wagon (w124) is thunking into each gear. Drive
it about for the day. Yup.
Mmmm I wonder, stick mini vac on line to transmission ok, onto line
before vacuum control valve ok.
Start car, vacuum from pump ok, behind restrictor (green plug) ok. To
transmission. ZERO
Ah, mmm system is fine if car is off, then zero if car is running. Oh
how clever.
Mutter order new magic box, which now instead of being a w123 part is
a w140 part...
