Oh, well either way it's not there lol so I figured I'd get a new one since I'm messing with everything down there.

 

I replaced my transfer case and while I was disconnecting the vacuum lines I noticed a line that was in my way. I removed it and set it aside. Once I got the new transfer case (3 weeks later) I went to installing it. I got the vacuum lines that run to the CAD on the 4 prong switch installed and the other hose that was tied to the 4 lines on the vent on the transfer case. After I completely installed everything I noticed the line I took out and completely forgot where it went to or how it attached. It says on the line Transfer Case Vent 5/16 185192634. It has a red clamp on one side and a metal hard pipe on the other with a hangar next to the metal pipe. Any help would be appreciated

 

Where did that line go to/come from?? What color is it?

 

Line is black with white lettering that says it’s the transfer case vent. Would it connect to the 5 lines that was attached to the 4 vaccum hoses that connect to the switch?

 

Also it looks like there is a space for the line to sit next to the fuel lines that run along side the drivers side of the truck along the frame

 

Vent line went from transfer case switch, up behind the motor. It's just a vent, so, it doesn't connect to anything on the upper end, just secured in place wherever you can find a good spot.

 

Just got everything installed and checked all the vacuum lines made sure they were on good. Now my truck won’t shift into drive or reverse. Also when I shift into park it makes a groaning noise. I made sure the transmission fluid was topped off. I’m at a loss here

 

Is the t-case in neutral?

 

No and I shifted the transfer case into all of the gears and tried to put it in drive and reverse and still nothing

 

Why did you replace the t-case in the first place? Was it because the truck wouldn't move??
