I have been at it all day on my vacuum system and may have fixed a couple of things. The vacuum line replacement with new rubber is certainly a lot of fun on the transmission modulator. Is there another vacuum hook up to the transmission other than this one?

On to other issues. Check valves, I don't have two but three. My first is a green valve that then branches out to two yellow valves, one with 1 outlet, the other with two. If the green one is a check valve, it is bad. The two prong yellow check valve is the one that supports the yellow line and the yellow and black line. The one feeding the vacuum tank is holding vacuum, the other leaks down quickly. I have not gotten into my drivers side door to sort that one out.

I have a Auto Zone knock off to replace the green check valve one I confirm from this board that it is indeed a check valve. I'll order the correct part after I figure out from you guys what it is.

And then there is the blue line, what does it do? And which one is the one that shuts down the ignition. That's the one that I most need to find. I am not able to shut my car off at all anymore unless I open the hood, and even then it is very difficult to get it stalled.

If someone here could point me to a good post or sight that goes through all of the vacuum line diagrams that would be great.

Thanks in advance to some references or help; beyond just the door lock system. I have Tom's book on door lock repair and I think I can get that part in hand.
