Tranny Vent leaks! Griner?

I have a 727 with a Griner G20 Transbrake & it leaks fluid out the vent. The Griner relocates the vent in the rear of the case at about 10 o'clock (a Plastic drive in vent like GM's) & plugs the original. Anyone got any fixes?
I heard of hooking up a catch can to it, don't like that. There isn't a vent out there :yikes:that relieves the pressure but won't let fluid escape..........?


Thanks
