Help with transfer case leak
 
Hi all,
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.

So that would mean that your transission is leaking and running down onto your t-case?

Yup rear trans seal it looks like, not too big a deal to fix. With the skid off your half way there...Jon

Ok. Is the little hole where the fluid is coming from supposed to be there? What is its purpose?

Any more info about the rear trans seal?

I was wondering that as well. Maybe it is a failsafe so you will notice it before your trans fluid gets too low and it overheats?

To let you know it's leaking.

It also lets the adapter between the transmission and the transfer case remain at ambient pressure...

That makes sense. I dont think my AA adapter has one, maybe it would be a good idea to drill a small hole.

What AA adapter are you referring to?...

Randonexplosion 06-28-2013 11:21 PM

4l60e to np231. I need to take a closer look but im almost positive there is no "weep" hole.

Randonexplosion 06-28-2013 11:23 PM

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.

Good luck.
