LOL. No dead bodies, but the day is young and the list is long.

No shaking at hot idle. Well, I shouldn't say no shaking. Usually not, but sometimes yes and only very slight.

I think my Climate Control Unit is dead, but haven't had time to troubleshoot it. Been dealing with a faulty gauge cluster. Since it's summer, I'll wait until august or so to worry about that.

Here's a summary of what I did to the vacuum lines under the hood. I'll refer to the schematic attached above.
  1. Remove all lines from #71 (Central Plug)
  2. Remove the Black line (bk) from the "T" connector that comes off the bottom of #65 (Vacuum Contol Valve or VCC) and goes to 71.
  3. Replace the "T" connector at same spot with a straight line that connects the VCC to the black vent line (a). This vent line travles through the firewall and into the cabin and is, apparently, not connected to anything. (see post above)
  4. Remove "T" connector between orrifices 62 and 63 and replace with a straight line connecting 62 to 63. This eliminates that white (wh) line going to 71.
  5. Remove all lines going to 36a and 60 and plug the ports left behind on 36a and 60. You can get vacuum plugs at any auto parts store for less than $3.

This process made my trans act like new. No hard shifting at all. And, as an added bonus, you get some spare vacuum lines and connectors.

The other thing I did, that helped boost my power, is connect the ALDA again. There are two connections. Both lead to a device mounted on the firewall (can't remember what it's called) The ALDA goes in the port that sticks out the front and the second line goes from the Intake Manifold (drivers side, back of engine) to the port that sticks out of the bottom. You may have to take this thing off the firewall to hook it up. I got lucky and was able to connect it without doing that. I got a huge boost in power. Drives like a gasser now. I have also heard of folk going directly from the manifold to the ALDA. Don't know much about that so you may want to poke around to find more info.

Hope that helps
