First, I must tell you, coming from my end of repair work on my X, I understand your stress. I just feel that you had all these things happen all at once. It does seem that when there is one problem there ends up being many more that follow. Well, this is just from my experience of course. Either way, the ZF Tranny I been told, either will give you problems from an earlier stage or won't give you any but die after 100k. Now, which one is right, I really don't know. I have 104k on mine right now, it still shifts nice and smooth, but you never know what can happen. Good Luck with your problem. Hope everything turns out fine.
