I don't think you need a new trans. Here is what I feel is the problem. Where the transmission and transfer case come together, there is a seal that seperates them. If that seal is bad, the trans fluid will go into the transfer case. That is why it is overfull. As the leak at the front, the front seal sounds like it is bad.
If the transmission is still shifting properly, it is fine. However, to access the rear seal, the transfer case has to come out and the front seal requires the transmission to be removed. You are looking at 20 dollars worth of parts + fluid replacement, and a lot of labor to remove the parts. If the transmission is still shifting properly, don't replace it.
