It just vents through the shifters as far as I know.

well my problem is on extended drives at freeway speeds it seeps 90wt out of the shifter base so i figured that the vent was clogged and air was pushing out there

Transmission and Transfer Case Breathers:

In stock form, my W56 transmission and RF1A transfer case(s) are vented through the shifter, there is no separate vent as exists on some other Toyota gear box designs. This presents a few problems, the obvious one is if the shifters are submerged in water, as the gear box cools and the air inside contracts, water will be sucked inside. The second, and less obvious problem is that gear oil smells and the venting fumes can often enter the cabin area, this is a more common occurrence since having dual transfer cases installed with less then perfect sealing.

Transmission Breather

So to fix this, I simply removed the shifter base off the gear box, drilled and tapped a hole for a 1/8" NPT fitting and installed a 90 degree NPT to hose barb fitting. Then I later used some sealant around the top of the inner rubber shifter boot to help seal it up from water entry. Once all the vents are in place (still working on the transfer case vents), I'll tie them all together with tee's and run a line up forward to the firewall and install a filter for the end of the vent line.
