OK, pull the hose and cap the port on the manifold. Nice combo in a 64. I had one back in 74. 327 and PG tranny. It rode smooth as glass to 120 mph!

Curious though, what kind of shifter was installed for the 700R4?

vacume line

I have a 700R4, rebuilt it and put a valve body from TCI that keeps 200 lbs. line pressure .This is suppose to keep one from wasting 3rd and 4th clutches if your TV cable is not adjusted right. Well, about vacuum line.TCI sent a vacuum switch with ground wire running through it, called them and they said to run it from carb. this operates ground wire to trans. plug. I am going to try it ,

Sounds like the vacuum switch they sent is to control converter clutch lockup.
