no they are not the same. Same design but the bell housing, torque converter, clutch pacs and so on are all different. You can put some of the inerds of a PSD 4r100 into an expedition to make it better, but the inerds of an expedition 4r100 will not hold up to a psd even if you could bolt it up.
The reason a PSD 4R100 is more $$$ is because it has beafier parts to it.
And by the way WELCOME to the site. Any more questions feel free to ask
