you have to use the zetec computer cuz that controls the zetec motor. i researched it and the trans are the same and everyone told me no there not the same but if you try to order a new one for either engine it gives same part number sdame exact commponet. i used my spi trans and car runs 100% perfect shifts smooth just like it did before the swap. you have any questions on your swap pm me.
