Wade,
you lucky freakin devil! It sounds like you have a Euro 300D based on your description of the manual climate controls. That is excellent! The old climate control was awful, the newer one has issues alot also. So manual controls is the best scenario. Do you also have cloth seats? manual sunroof?
Anyway, it sounds like you may have a 3/2 valve on top of your valve cover, which is what my wagon has. I'll attach a couple of pics, but basically, and you'll have to play with this some, but one line comes off of main vac line to 3/2 valve. One goes from 3/2 valve to tranny modulator, which I'm guessing is on passenger side of your tranny. The third line is capped/plugged.
The 3/2 valve lessens the vac to tranny during acceleration, and combined with the adjustment of tranny modulator caused tranny to shift. Too much vacuum and the tranny shifts early and also will flare shifts. Too little or no vacuum and it shifts incredibly late and hard. Play with the vacuum to the tranny, and then worry about adjusting modulator. do a search on this forum for tranny vac adjustments, and also look up at stickys at top of forum. You have an older style of tranny and modulator than alot of the posts, so just look for the ones that seem to describe your components.
On the tranny modulator, clockwise makes shifts later, ccw shifts earlier.
If you have a different setup than the 3/2, then like Emily Latella(or was it Rosanne Rosanna-danna) would say, "Nevermind". (that will be lost on the young folks)
[see pic with this thread. It wouldn't let me attach pic again]
Yipes I guess I am glad I have a non turbo
