Are you 100% positive? I'm asking this because today at the dealer I asked for the MTX-75 part number for a 2006 and it come up to be 4S4Z (at least it was the number on the computer screen), then I went to a junk yard and there I found a 2005 focus that was made on 08/05 and the transmission part number in there said 4S4R so I'm really confused right now. I guess I'm going back to the dealer again tomorrow.
