Putting a new tranny in a 2002 sierra 4x4 and I can't remember where all three of those lines run to. I don't wanna have to drop the damn tranny back out to hook it all up so I need a diagram so maybe I can do it without seeing it. Anyone know where I can find that at? I have the two lines that are connected by a bracket( I think they bolt on the top of the tranny) they have little white caps on one end. Then it looks like the transfer case has its own vacuum line. Anyone know where I can find it?

Ones with caps that go to top of tranny aren't vacuum. They are breathers. One with connects top side of tranny about midway on passenger side. The remaining length just runs to nothing and dumps at the back side of the transfer case. On a 2003 anyway. The other runs to the transfer case and connects topside/driverside, right above the the electric acuator.

Hope this helps.
