Tranny vent

Were and how does/should a 727 (Scout) tranny vent?

Off-road application, so any vent would need to be closed or remote mounted to keep the crap and water out.


Iirc the main vent is in the front of the housing behind the converter. And iirc also for off-road application its wise to plug this vent avoid sucking in water or other junk as well as in a roll-over situation.

1) whats the recommended method of plugging this? Without tearing the tranny apart to clean out any shavings from a drill and tap procedure.
2) is there an auxiliary vent one can tap into for a remote breather?
3) how much "breathing" does a 727 need? Common practice for differentials and t-cases lately has been to use basically a little rubber "bellows" that allow expansion and contraction of a fair amount yet it still keeps everything sealed and keeps fluid from escaping when you go greasy side up. Would this be sufficient for a 727?
 
There is a section on venting in the 727 guapo sticky. The bellows idea is an interesting one, haven't seen anything on that.
 
Guapo it is!!

Let me peruse and see if I have anything else to ask.


Let me see what I can find on the bellows.

Here's an example. I've heard they are only like $5 from your local snowmobile/atv shop, but you have to to a little research to find the right one.

Mark those won't work for a transmission as there's too much volume to vent. I tried it and when the trans warms or "expands" it will push fluid out the dipstick.:icon_gonk:
