What is this nipple for? 2007 Vue Honda 6.
 

There a nipple on the driver's side (lt side) that has a nipple on top doesn't go anywhere. Can someone tell me is this a vent that should have a.hose on it? There appears to be some transmission fluid on top of the transmission as seen in pic so, MAYBE, a hose came off or something? Any help appreciated!

What hooks up to this nipple? There appears to be trans fluid on top. DRIVERS SIDE TOP

Since I don't know anything about Honda engines (except motorcycles), I won't even venture a guess.

Pressure test port?

Hi dentpusher, I checked on my V6 Vue today, and that nipple is for the transmission breather vent tube which is attached to the underhood fusebox:

The '05 Honda Pilot (with similar but not exactly the same transmission as ours) Honda part number is 21320-PVG-000 , "Tube Assy., Breather": https://www.hondapartsnow.com/genuin...205AT&filter=()

Thanks for checking, redview. I suspected as much. My tube is still there but i can't see the bottom end and feels attached, I'll have a closer look. That is what i was suspecting. ✌️

No problem, good luck :D
