Transfer case 2 Options

[90GSX]

I didnt want to jack mitsu 90's thread, but im in the process of having my motor rebuilt and i did the pulling myself. Well when i pulled my transfer case, i didnt bother to drain it (i was just being lazy) and just unbolted it. I went by a Vfaq on doing so and they said to be careful about tipping it or you will spill trans case oil all over you, well i did tip it ( well tip, rolled and everything else) and didnt spill a drop, well after seeing a few threads on here, i decided to unbolt the drain plug for kicks and giggles, but to my surprise there was no fluid that came out, not one drop. So im guessing this is what the recall is supposed to cover? I do have paperwork from the previous owners and there is a paper showing it was checked quite a few years ago and everything was ok. So my questions is what should i do about it? I have no idea how long it was going like that, but it never howled, whined or made any grinding noises. So to avoid the hassle, should i just replace the seal (shouldnt be to expensive) myself and just go with it. Take it to the dealer and hassle with them to try to get it replaced?, or wait till my motors done, slap it all back together, and then take it in?, or just replace the whole unit if someone has one? Im really dont know if its worth fooling with the dealer if i can just put a new seal on it myself and go with it, or should i not take my chances there has been damage done to it and just replace it to be safe? Will a dealer honor the warrenty if its already pulled, or do i have to have it on the car itself and take it in that way?

also should a chrysler (20 miles away) dealer still cover my car even though its a mitsu eclipse? or do i have to take it to the mitsu dealer (about 100 miles away) itself?
