164 automatic transmission ECU - used, my mechanic purchased it trying to trace down a problem but this wasn't the problem. Also, O.E.M. 12 disc CD changer. This is the piece that mounts in the trunk, not the CD player in the instrument panel. Comes with the cartridge that holds the CDs and all 12 individual disc holders. This was purchased used but I didn't get a chance to install it into my car. I no longer have the car so have no need for either of these parts. Price is for both items.
