Big leak!

While under my 1994 S-10 Chevy Blazer I was changing one of my spark plugs and noticed transmission fluid on the underside of the truck still wet, and also some silver/gray fluid on a box right in the center under the front seats. Now I haven't drove the truck in 4 days and there's this fluid on the underside still wet. Anyone have an ideas what the silver fluid is and where the transmission fluid is coming from.

Remove the top fill plug on the transfer case and see if anything comes out.

Your transfer case could be overfilled due to the usual transfer case to tranny seal.

How about the silver/gray/metalic liquid...is that some sort of chemical reaction or something?

That is weird, I don't think there is a liquid in our whole truck that is that color.
