Default transfer case leaking

Newbie
My 2000 Astro awd is leaking fluid from the transfer case. I filled it about two weeks ago with 2 litres of Auto-Trak(blue) fluid.

I now see large leak spots on the ground where I park and when I pull away,I can see a visible trail of fluid leaking.also on long trips(highway speeds) I notice "oil" spots on the rear door window.As I look under the van,I notice a good deal of fluid
on the undercarriage around the transfer case and other areas as well.

any help? Thanks,Tony

Check the plug, gasket, and the places where the case is bolted together.

You will have to clean it up and watch for the leak, it could be the seal or the case halves. If its the case halves i wouldn't use anarobic sealer like it calls for, use silicone and let it dry before reinstalling.
