I know its not a buick but my question is will a 2000 Taurus AX4N fit and work on my 1999 Taurus with AX4N Both Duratec engine equiped. I think the only difference was the part#. I called ford and they said not to do it or ill screw something up.What do you guys think is it really that big of a deal. O and my tranny has a tag on pan that says to refer to the 2000 model for tranny info. I think its a late model build. Any info from you tranny guys out there will help me decide wether to purchase it. It is brand new and i can get it really cheap. Thanks Rudy
