I have a 88 300zx and i just recently rebuilt my engine. When I started to put the engine in I found a long metal tube coming from the driver side of the transmission. It connects to the tranny by a rubber hose on the driver side which sticks out about half way down. The problem is I have no idea where the other end goes. It looks like a vacuum hose to me but if so where does it hook up? Any help is appreciated.

 

dude, pics

 

Yeah, pics please. Also check out the freebie service manual and fiches at XenonZ31 Reference See if you can locate the part on the FSM diags or on the fiche.

 

I wonder if hes talking about the AIV Stainless steel tube. But that dosnt run to the tranny, it connectes to the exaust downpipe.

 

OK i just figured out there is sup post to be a metal hard line that connects the Vacuum Diaphragm to the intake manifold for the transmission to operate correctly. This what your talking about?

 

Thanks so much! sorry for no pics.
