First, have you identified where the transmission fluid is coming from?
Second, as far as the transfer case not shifting to 4lo, you need to unplug the actuator on the transfer case and see if it getting power when you push the 4lo button. If it is, chances are the actuator is bad. It isn't uncommon for them to go bad.
Let me know what you find.
