Where is the vent on a 7020 PS. Are there 2 vents? I have a leak that I CANNOT locate. I had many small leaks, most of which have been fixed, but I can still EASILY lose a 1/4 gal/hr. It was closer to 1 gal/hr, before I fixed the other leaks. Oil ends up on the rear tires sometimes. Sometimes not.  Thank you.

Is your fill tube loose where you check transmission oil? They break off where they enter range transmission housing and also get loose.       MACK

Thank you very much sir. The tube certainly wasn't loose, but there's a crack about 3/4" long in the 'flare' that bottoms on the top of the transmission. It may not be my whole problem, but it's certainly part of it. Thank you again.

Just FYI, The vent is directly under a cab cross member about 4-5 inches forward of the oil fill tube and directly center left to right, it is a street ELL with wire mesh in it.......Or should be anyway.
Still in use:
