    I have a very slow leak on my transfer case on my truck. I took it into GM today, they said it'd be $890 (parts/labor) to repair it- it is a series of gaskets, seals and an insulator needed to fix the leak. The parts costs add up to $229- must be a h#ll of a lot of labor to fix it! Anyway- I wanted to see if you guys had had a similar issue, and the best way to fix it. Can a "no leak" product like golden eagle transmission leak stopper fix the problem, or is it worth the $890 to get it fixed by GM? What to you think?

    If it is that slow of a leak, then I'd just make sure everything is topped off and let it be.

    It probably loses 3-5 drips per day on my driveway, seems to lose more when the oil is hot.

    Man that sucks. I'd watch it but have it fixed before winter hits. Wouldn't want to be stuck in the cold.

    Don't mess with it, just keep a eye on it. If it gets worse then I would get it fixed. My '99 2500 leaked until the day I traded it. Also, don't add anything other than the recomended GM fluid and yes you have to buy it from GM. In order to fix it they must disassemble the transfer case and yes its alot of labor, been there done that. Are they sure on where its leaking? Reason I ask is because the rear output shaft seal on my '99 had to be changed twice due to "sweating". Dealer told me that its common problem.

    I was looking at it leaking- I don't think it is the rear output, as the leak is right near the 4x4 actuator towards the front of the case.

    your obviously not in warranty...DONT TAKE IT TO A DEALER! Much Much cheaper at a reputable garage.

    True- the problem is there aren't a whole lot of reputable garages around me- anyone in Northern, NJ know of one?

    Also- its leaking worse now (about 2-4oz/day) that the dealer took it apart and put it back together with the old gaskets- anyone know how much oil is in the case, and if it is okay to drive with it leaking?

    my friend drove his GMC with a leaking front diff, and a cracked transfer case, it ended up destroying the 4x4 drive train. I would just bite the bullet and have it done.
