I had that same thing happen to me. Ford has a redesigned fix part for that. Its the whole front of the trans. You can't get just the cone anymore.
Here's the part number (3R3Z-7005-AA updated throwout bearing guide)
They list for $370.33 but I get cost plus 10% at the Ford dealer by me. I think my cost is around 240.00 I'll get it for you if you want. Here's a pic of what you will need to replace.
