CHEVY TRANSFER CASE LEAKING AT SEAL

2002 Chevrolet Silverado

Transmission problem
2002 Chevy Silverado V8 Four Wheel Drive Automatic 101000 miles

In the last several days, the transfer case has developed a leak either at the seal between the two halves or around one of the bolts that hols the halves together. Two questions: is there a way to fix this by adding a liquid sealant to the transfer case, and second, about how much should this repair be at the Chevy dealer?

As far as a price, it is hard for me to tell because I don't know where the leak is coming from. It shouldn't take much more than 3 hours labor to remove replace a gasket and replace. As far as the parts, gaskets are cheap.

If you wipe everything off, can you tell where the leak is coming from?

Best I can tell its either leaking through the seal or from one of the bolt holes. Its not coming from a hole in the case itself, I'm sure of that.

Chances are a new gasket will fix it. As far as the additives, if they work, it is only a temporary fix.
