I believe a 99 or 2000. I know it was after 98 becuase the 96~98 4R70W's are a direct swap but in 99 ford changed the plug's a little and you'd either have to splice on a new connector that would fit into the trans or get a 99+ auto tranny harness. I talked to dave about it and a few other guys at modular depot. There are several guys who have done it in thunderbirds actually.
