Posted on another site maybe someone can help me...

Just purchased my first Tahoe (2000 /new body style) about two weeks ago. However this Tahoe is need some engine work (when I say engine work I mean I have a rebuilt on the way )

Body is clean and straight and minus one window motor all other electric work

Got the Tahoe very reasonably because of that (engine) but I did find out something that just recently started. I knew about the dreaded "pump rub" even before buying this Tahoe but for the most parteverything looked fine underneath until I noticed a leak from the transfer case about two days ago.

I was already prepping to buy the rebuilt housing with the "pump rub fix kit." However I noticed that the leak wasn't coming from the actual housing but from the transfer case shift motor housing mated to the transfer case.

So my question(s) is this: Does this module actually have fluid inside to leak or is it coming from the transfer case through the module? If it's the latter does this mean my transfer case is failing or it's just a seal that needs replacing?

Coming from a Chevy Astro AWD with 279k miles on her before her untimely demise I never had such issues so little advice would go a long way...

Thanks!

Anyone?

Gotta give it a little bit of time, but someone will chime in.

To answer your question, I don't believe there's fluid inside the module so it sounds like there's just a seal that needs replaced to keep fluid from coming out of the T Case. Welcome to TYF

You're welcome. Hopefully you enjoy the site. We are quite a bit more active than the other Tahoe site even, though, many of the staff are the same as well as the other members. It's just really slow over there.

Another question (I promise to be patient ) is there a part number for this seal that I can get separately or do I does it come with the module?

I would check out Rock Auto. They usually have all the stuff listed nice and neat and give you part numbers for everything. It'd probably be under transfer case or driveline.

i like to use gmpartsdirect for diagrams and then use rockauto for purchasing.

Isnt it an electric motor bolted onto the outside of the case? Just want to make sure IM picturing the right thing. If so, yeah no fluid inside. All the ones I have done come with the motor.

Yes It's the electric motor. Thanks for the assist!

Sorry for the late reply. I was down with the flu.
