I have a leak in my transfer case. It is leaking from a tiny hole almost right above the transmission mount. It has been leaking for some time and it was only just recently that I took the skid plate off to get a better look.
In the picture you can see fluid beading up and the hole it is coming from directly above it.
Though I remember during WhyJs engine swap thread he noticed trans fluid leaking through the adapter due to a seal on the trans side that he didnt install. So I would probably notice it without a hole.
Morning, yes your tranny output shaft seal is leaking, very common.
Drop front and rear shafts.
I don't drain tranny fluid, just have a pan rady.
There are 6 nuts on the transfer case 9/16's, the top 2 are tricky. They are a breeze if you pull the center console and the shifter, if its an automatic. Either way, no big deal, the top 2 are just a hassle.
Put a rolling jack under the TC, makes it allot easier.
Disconnect the TC linkage, screwdriver and pop it off.
Disconnect a few electrical connections on top of the TC case.
Pull the TC out.
Pull the tranny seal.
While its apart, replace the TC seal as well. Seals are less than $10 each.
Takes about 4 hours the first time. It's not hard just takes some time.
There are plenty of really good posts on the process.
