Default Help me identifiy this piece

While I was under the car yesterday I saw this thing tangled up in the fuel/brake lines by the transmission. I don't know what it's for, so any help is appreciated.

Looks like a vacuum switch or tee of some kind...

To me this looks like its the vacuum T that goes tied to the top 4L60E auto tranny vacum line and the other 2 hoses that run behind the block above the tranny case.

I have a 4L60E. After some searching I gather this is a "vbp-vac" that the forced induction guys use for the transmission. My car is pretty much stock, and I don't know much about forced induction, so I really don't know what to make of this since it was tangled in there pretty tightly.

It's like a one way valve to vent the 4l60e trans. It's supposed to sit on top of the trans case

that's what i said as my car has one,

OP, have you checked under your car to make sure all vac lines leading to your top tranny case are in order and not dangling around.

Actually I did notice a short length of hose that was disconnected, but I didn't have time to inspect any further, the car is currently in the shop, is this something to be addressed urgently? (As in before I drive the car again)
