Carburated Engine....now tranny trouble

I carburated my engine on my 89 Full size Bronco, when putting it all back together, I got as far as putting the transmission in. Now it won't move. There is one vacuum line off of the transmission (C6), when I hook it up to the back of the carburator the bronco will move forward in every gear. When I take it off the back of the carburator and it will go in reverse in every gear. I've thought it could be a linkage problem, but can't seem to figure it out. Any suggestions would be really helpfull, I'm about to sell it, but with 5K invested it's a little hard to do.

yeah i got a suggestion.. hook up a t in your vacuum because the reason it is doing that is some vacuum ports suck and others blow
