There is an XFi Transmission in my junkyard. looks to have a little surface rust on the inside, but nothing that can't be fixed. I'm unsure if there is a demand for these or not, but I thought I'd throw it out there in case anyone is interested.
I believe they charge around $50-$75 (can't remember) for a transmission. There will also most definately be a core fee, as well as shipping to your neighborhood. This could make the transmission costly and not as desirable.
