Thank you for your replies
So any 98-02 transmission xBCB will be fine

I found some here on local private & junkyards that i m considering purchase.
What problems, if any, a trans will have if it remains in a wrecked car unused for a period of 1-3 years or more?
You just need to drain the old trans liquid and put a new one? Or is there any specific procedure like any kind of "cleaning" etc.
I heard that few, if any, put some kind of preservative in there to avoid rust but i think that's rare to find.

Thanks again
