since ther is no fill plug on the marlin crawler dual transfer case adapter plate how do you fill the first tcase ......i dont think that the tranny and t case share the same fluid but idk and i doesnt look like the fluid from the first tcase can go through any of the holes in the adapter plate

You can fill the first case through the BIG hole on top where the shifter is bolted to. I just put three quarts in the rear case and call it good. The oil will flow through the adapter to the crawl box.
