Thanks for looking at this post. I am having time of it diagnosing a system of problems...

1985 300TDT 176k or so. Need to know what parts of the vac sys need to be adjusted or replaced - for the first 10-20 mins of driving, until it reached about 80c or so...the tranny clunks as it downshifts back to first at 17mph. This condition stops however if the a/c (which mostly works, sometimes) is on. Having the a/c on also makes the power locks work much better (well, not to mention that the vacuum reservior has been replaced by a 4.5 gal tank for holding diesel for startups and cool downs - runnin on SVO the rest of the time - main tank conversion)(pretty cool, too). But the vac res there or not doesnt change the fact that the locks work when the a/c is on. When the tranny is warm, the downshifts are smooth, a/c or not.

Until yesterday, when I decided to plug what i thought was the leak. There is a part, which probably needs replacing, that apparently at some point had been sealed because it has a leak. It is the component that kind of looks like a blue and white fishing bob. I thought a little tape wouldnt hurt, but after i did it - the locks wont work at all, the a/c does not smooth the downshifts, and I have to use the stop button to shut off the car (which i of course do before i shut off the ignition as not to put an extra load on the alternator). the only other thing i did was extend one portion of the throttle linkage 4 turns because it seemed like there hadnt been enough power in the pedal.

So - I hope this is specific enough for someone to poinnt me to a post or something that would help figure out what is going on with my car.
Thanks for your time...

Glenn
