1. how many vaccum lines go to the transmission? I just finished an engine job and I seem to have an extra vacuum line unhooked at both ends. Don't laugh...I know...I found it near the rear of the intake manifold and I think it may go to the transmission for shifting? If anyone can help, thanks.

2. also, the vacuum line from the diaphram pressure regulator...where should it go to?

Thanks
