Can someone identify this part?

This fell out of the top of the transmisiion or out of the body when I passed the new speedometer cable housing over the transmission. Is it important and if so where does it go? Seems to be all plastic , top is loose like it might be a vent?

Rear axel vent.

I think thats a breather. There's one on the trans and another on the rear axle/diff also.

At one time I posted the PN for it - can get them in bags of 5 from Rock.

Vent, breather all the same.

It's from the transmission then, how do I figure out where it goes, I can't see up there.

You'll need an Inspection Mirror.

Do you know about where it goes so I know where to look?

I think it's from the transfer case. Which model do you have?

I believe all of GM's autos used just a simple little plastic line as a breather?

More I thought about it....if yours is a 4WD - its probably off the transfer case.

I got a pic of my old 203 handy. The vent is on the rubber hose... right where the speedo cable goes.
