where does this hose go?
 

hello,

2003 suburban 2500 8.1 np 246 tcase

While reinstalling the t-case noticed this hose hanging down passed the transmission. I don't remember seeing it while taking the tcase out.

Its not the one that goes to the nipple on the t-case that one is on the other side and is shorter.

Any idea where this connects to or is this some type of loose drain hose?
pics to come

probably transmission case vent

Does that need to attach to somewhere or is it just for venting

Could be a transmission vent.
The fuel tank vent is sometimes routed to a filter up near the transmission to cut down on dust ingestion. IIRC there's a TSB on this.
That hose would be about the right size.

it is a vent that has a tee just down from the trans one end goes up to the top of the trans with a vent the other ,well you found the other end. It isn't specific to just the 3/4 all are like that
