Vacuum line or breather hose?

[Pali7]

Hi, I spent too long in repairing my wife's 9-5 and I forgot where this line goes. It comes out of the top of the automatic transmission. I can't find where the other end goes. It's larger than the smaller vacuum lines. It's circled. I looked for a vacuum line diagram, but haven't found one. Thanks for your help.

It's the transmission vent/breather line. It goes nowhere.

Thanks Mike! It was driving me nutz.
