Thanks GM
GM,
Welcome to the THREAD on a very popular subject for owners of W123, W124, and W126 Benz(s)!
Yes, it helps to know the proper name of any components and secondly to be able to access the correct vacuum diagram for your AutoTrannyVac-Shifter System. I believe yours is the same as in my previous POST... but here it is again on a popular tranny rebuilder's WebSite here in the San Francisco Bay Area: http://www.peterschmidtransmission.com/vacuum/1977_1985/616_617_91/616_617_91.jpg.
I think you will find your "white bleed thingie" to be the Vacuum Control Valve... #65 in this diagram. I recommend you save a copy of the diagram as best you can and print out a legible copy so that in your POSTs you can refer to components by their proper names and/or # from this diagram along with a reference to the diagrams's http address!
You also might want to go backwards in this THREAD and read some of my discussions of STATIC and DYNAMIC vacuum control systems and try to understand the point I have made that these Tranny-Shifter Vacuum Control Systems are a combination of both STATIC & DYNAMIC.
Also tell us something about your car...
Q1 - miles on car?
Q2 - miles on your current tranny?
Q3 - how long have you had the car?
Q4 - daily driver or not?
Q5 - also what are your tranny's shift symptoms?
Also even a meager digital camera that has a Macro mode for closeups can be a Godsend when trying to describe something!

IF you have no idea about Q1 & Q2... then you might want to POST your VIN next time and we will look up whatever information we can on the car using a popular Russian WebSite for such. This will give us your engine & tranny's S/N(s) which you can compare and maybe learn something more about your piece of fine German engineering.
There is a lot of information in this lengthy THREAD so browse through it and see what you can pick up... but first download your diagram, take an inventory to see what you might have missing or extra... and start becoming familiar with the various components... and count your blessings that you don't have a 1985 California Benz!
Regards,
