Figure 20 minutes to leak 1 drop. 20 drops = 1 mL. The transmission can malfunction with 1L or 1000 mL leaked out. 20x20x1000/60/24 = 277 days before the transmission malfunctions from this leak, assuming it doesn't get worse.

For what it's worth, check the transmission breather isn't clogged. The transmission and transfer case breathers are between the back of the engine and the firewall:

Good point on the breather! That would be something to check right away. If it happens to be clogged, unclogging might reduce or maybe eliminate the leak.
