Nah. Beat the hell out of it so you can work on it. It's a labor of love.
You have the AX-15 transmission. Good trans. I can't believe you broke it already. lol
If you call around and get some estimates on having it fixed it will give you an idea of what is involved and how much.
I personally wouldn't dig into mine. Maybe. But I've been inside transfer cases many times.
Just depends on your experience and what tools you have.
Where are you located?
