I was under the truck last night doing an oil change and noticed that I have recently developed a leak at the seal between the two sections of the case on my 208. It looks like a pretty simple job to drop the TC, but what awaits me when I split the 208 in two pieces to redo the seal? The pics in my Haynes manual don't really make that much sense to me(maybe they would once I started/forums/images/icons/tongue.gif). What are my options for the seal? Do you guys use RTV or is there a gasket available from GM?
