If you are going to just have the fluid flushed out do it yourself since the trans filter is not being changed. Get a transfer pump and pump the fluid out replace the fluid drive it for a day and do it again. The torque converter will have old fluid in it even with a shop flushing it unless they have the trans running.

I just thought being a Ford you might have one of there sealed trans and I'm not sure how to access the fluid that way.
