I was surprised too. No smell and no leaks that I knew of. Mechanic did the fill and he said no leaks also. He said he put an angled screw driver in there and it was not wet at all. The truck is very well maintained and my wife drives it mostly as a grocery getter/kid taxi. I think the fact that the transfer case probably didn't get too hot from long trips or lots of traffic and she is not an aggressive driver coupled with the fact that we really haven't used it much in deep snow or ice probably saved us. Going to change it again next spring.
Whoa, that's very surprising, usually the first symptom is a foul burning oil smell
and slow drip leak from the breather valve on top.
Did you try reaching the top of the transfer case and see if there was any oil on top?
Also did you use the tiny 1/4" diameter round tube of the electric pump to try to suck out the oil,

you have to really get it in there, it's about 4-5 inches to get to the bottom of the transfer case.
The oil will not be instantly evident when you remove the plug, you really have to
get the tube into the transfer case as much as you can and angle it downward.
I was only able to get out about half a 16oz bottle the first time I did it.
I'm assuming you never changed the transfer case oil since you bought the car ?
61,000 miles is very low mileage for a 2008, but the OEM oil is 7 years old
and more than likely, the OEM oil turned to sludge like the photos in this link:
You can still try to save it by filling up with new oil and try to dilute the sludge and changing again after 500 miles.
Or if you're mechanically inclined try to disassemble the transfer case and clean it out, but that's way above my skill set.
I just bought an 08 cx-9 and decided to swap out the transfer case fluid. It had 81k miles on it and I wanted to be safe than sorry. Everything went well, I used the electric pump to suck out the fluid. About two days later the TC started leaking. Any ideas?
I just got an 08 with about 55K miles on it. I did the drain myself and you really have to work it around a bit to get to the oil in the transfer case. Even then I only pulled out a few ounces. I filled it up and I am going to do another drain and fill at 60K miles with my next oil change. I guess what I'm trying to say is it can be pretty sludgy around the miles that our CX9s have on them if the fluid hasn't been changed before.
