Buckshot stated awhile back that he did his through the top. Even though it was a Duratec, it should not matter. Basically, he pulled the engine, leaving the tranny in place then removed the tranny. He stated at a time of about three hours IIRC, but that is with plenty of experience. You will not be able to pull them both out at the sametime!
The CD does state that the tranny should be removed from the bottom by way of supporting the engine with a brace, unbolt all mounts and connections relavent to what you are removing, drop the subframe and while supporting the tranny with a transmission jack you lower the tranny out of the engine bay.
If you just look under the hood long enough, you will be able to see how both methods would work.
And not trying to sound like a salesmen or anything, that Service CD can give a whole lot more insight into jobs like this, rather just instructions. Get the CD, look over the procedure then go look at the car. I am sure will could find some steps that you would do differently. It's only a few bucks, so what would it hurt?
