T20 vent question

[olds455]

ok , I have a Attex 500 superchief, it runs and works great. I take it out now n then but last time I noticed tranny fluid coming out of the top seals where the forward n revers levers are. I started looking for a vent cap or some way for it to vent pressure that might build up when it gets hot. It doesn't have one anywhere that I can find. Do these have a vent anywhere? Thanks

The top "plug" should have a vent in it.

Look at the second picture in the T20 Rebuild Instruction article. You can see the top plug that amphibious drew mentioned. In the center of the plug, you can make out a circle. That is the vent.
