Vent tube on 96 904AD

Can anybody tell me the location of the vent tube on my 96 auto overdrive 4wd? Drove it about 30 miles and ideled around in the pasture checking cattle, on the way home it blew out about a quart out the front seal.

Found my vent tubes. The one for the trans. and for the transfer case come up by the dipstick connected to the end of rubber hoses. Do not appear to be plugged though.
