2004 ultra tranny problem
at sustained speeds of about 70 mph my ultra is spewing oil from tranny vent it is not overfilled it is gaining oil from the engine how many avenues is there for this to happen ie gaskets or seals

the twin cam tranny is completely separate from the motor ( as are all HD Big twins )
check that you have correct dipstick or even drain and refill tranny with correct amount of correct type fluid per your manual ( about a liter).
do check that the vent is clear- wasps often make a home in the tranny vent

Oh, you are right the oil pan is shared, but fluids shouldn't be able to mix...the tranny drains from a hole in the bottom of the tranny case, through a passage in the rightside of the oil pan, then to the drain plug.
I don't see how the fluids could mix unless the drain passage has been busted due to overtightening the drain plug ( or a busted tranny case)
you may have to drop the pan...
if you go to:
http://partsfinder.onlinemicrofiche....HOUSING-W/-PAN
click on motorcycle, then select model year, then model, select transmission housing with pan
you'll see
if I wanted to check this, I'd use compressed oil to pressurize the oil tank at the filler to about 25 psi - then watch/listen for air escaping

The primary vents to the tranny via the clutch pushrod threaded adjuster. You'll notice that there a "flat" on one side of the adjuster so that there's always avaiable venting if needed. Could you have engine gases blowing past the jackshaft seal thereby pressurizing the primary?
