I had the same question 4 years ago. When I got our 68, it also had a late model C-4 tranny in it with the same modulator. The previous owner had about a 4-inch tube on the other port going nowhere (open). I was afraid to plug it or remove the tube, since I had no clue what it was for, so I just left it hanging there. Tranny runs great so I haven't messed with it since. But, I would still love to know what it was originally for, or if I should cap it.
