Acording to my tranny guy, seals don't just start leaking for no reason. He gave me all sotrs of possible problems like those Zeeb has already covered, then discovered that the pan gasket had sprung a leak, so I wound up with only a bill for routine service. This was a 700-R-4 on an '84 K5 blazer, but the transfer case may have similar issues. Good luck. CB
