Thanks to everyone that helped with the instructions with removing the 3 speed manual. The swap went very good and the C4 is purrin' My uncle was very happy with the job.

We took her around the block and it's smooth but doesn't shift till really late since the vacuum modulator isn't connected. One thing I noticed was when we put it into PARK, it makes a weird quiet hissing sounds for about 4-5 seconds and then dissappears. Anyone know what that would be? The converter was properly meshed and mated very good with the flywheel. The fluid level is perfect. Since the vacuum modulator isn't connected, we weren't able to shift it into 3rd gear. Just a short 25 mph trip around the block.

And the shifter has 2 wires coming from it, the trans also has 2-two pronged wires coming from it. Where do those connect to?

What size rubber hose do we need for the vacuum modulator?

Thanks in advance.

b. 3/16" IIRC. There is actually a metal tube for the modulator that runs down the transmission side, with only about 3-4" of rubber hose at each end. It attaches to a metal clip at one of the bellhousing-engine block bolts at one end, and a clip attached to one of tailhousing bolts at the other end, I believe.

a. Ok, so the 2 pairs (4 wires total) coming from the neutral safety switch are the reverse lights and neutral safety lights? How about the 2 wires coming from the console shifter? I assume those 2 wires connect to one of the pairs coming from the transmission.

b. Yup, I knew about the steel tubing but I'm not sure the parts stores sell those, so I was just going to use a rubber hose all the way through.

Thanks for the speedy response SteveL!!

b. You can easily bend brake line to do the job. Steel line is less prone to being sucked close, and isn't as floppy and prone to damage.

The two prongs on the tranny are a switch that is activated when the tranny is in reverse. Those will hook up to a connector on the car to turn the rear lights on when it's in reverse.

The other two wires, I believe, should be jumpered together. There is a pigtail that makes the connection on both sides easier. Junk yard?
