Help- Vacuum problems

[leeb]

Help, I have a 1984 300D TurboDiesel and it seems that I have several vacuum related problems. The trans shifts hard in all gears but if I floor it it seems right. THe hose to the trans holds vacuum just fine.

Also on the picture attached - if I disconnect the hose that has the green thing on it, should I be getting vacuum at the top of the white thing while the engine is running. ( I can't feel any if I put my finger on it - the same for the side outlet) Also the hose that goes to the black thing at the top of the engine that I have circled is losing vacuum. What is that thing and should I be losing vacumm at it?

My door locks seems to work fine - although I can't lock the doors from the inside, I have to use the key. They hold fine overnight and I can lock them about 6 times without running the engine.

I'm trying to chase down the ACC not letting air through the center vents only the defrost. I watch the diaphram move by vacuum when I take out the glove box - so It is getting vacuum there.

I would suggest looking at a vacuum schematic. At idle there should be no vacuum at the green vacuum dampener. It is on the other side of one of the vacuum microswitches on the valve cover under the black thing. As throttle is moved, before actual pump movement, the switch closes and vacuum is presented to the proportioning valve (white thing - this is a proportional controlled leak - it leaks more at larger throttle positions). The vacuum that goes to the trans gets reduced by this leak untill there is no vacuum at the trans at full throttle. For more info see: http://www.continentalimports.com/ser_ic20242.html

I don't have a vacuum schematic or diagram. I have a 201CD for my 190's and a 107CD for my 82 SL. Where can I get one in a hurry, or can someone email me a diagram? I really need this ASAP

Thanks
