I am trying to get my 66 running (302 w/C4 tranny) but am having trouble figuring out what a metal line coming out of the left side of the transmission is for. Attached is a picture from the manual that has an arrow pointing to the line that I am referencing. At first I thought this might need to go to the intake (but that should be the vacuum modulation line which is on the right rear part of the transmission). Does anybody know what this line is, is it a breather line, where does it connect to, etc.??????

Thanks in advance for the help!

yes its a breather tube.

 

Thanks Wrench, should I just run a rubber hose up to the intake manifold and put it into a vaccuum input? Can this vent to the atmosphere?

It is justopen nowandI ended up with a "pond" of tranny fluid on the floor (I started the car and ran ita few minutes and put it back in the garage - I came back after being gone for a week and found a puddle of tranny fluid on the floor - so I need to know where to run this line).

Thanks

 

anybody have any idea where I should route/connect the breather line that comes out of the left side of the D-4 tranny? It dumped fluid all over the floor which was a bummer........

 

It doesn't go anywhere. Just open where the tube comes out. No hose. If it is dumping fluid there you ahve other problems

 

anybody have any idea why I would have fluid coming out of here. This is kinda bizarre as the car was put away for a week when I went on vacation and I came back and the fluid was on the ground. Any ideas?????

 

that breather line is used to permit the fluid to get hot and expand without blowing your seals out. It's one of the negative aspects of the C4, IMO. It just so happens that breather line is just above the shifter arm and that too has a seal. Attach about 6 inches of5/16 or smallervacuum line to the end of the breather line and turn it up and tie wrap it. that will let the tranny breath and not drip fluid all over the place. Either you a have too much fluid in the tranny of the torgue converter is back flowing into the tranny when it sits. If you're still dripping, then it's probably theO ring just inside the shifter arm.
