2006 Mustang GT 3650 removal problems!!

Cutting off that upper factory mounting tab was the ticket! As I said above, I cut off the one right above the starter bulge on the flywheel housing. That is the one that catches on the tunnel when you rotate clockwise to get the trans out. Getting it back in was fairly easy after that, just need a lot of angle to get the input shaft into the clutch opening, then jockey it up into place, raising and reducing the angle a little as you go. Getting it to go that last 1/2 inch is a bear, but not so bad if you VERY CARREFULLY use the bolts at 9 and 3 o'clock on the bell housing. Finger tighten only, evenly, check all around for the same gap, then wiggle the trans around till you can finger tighten them some more. Keep doing this till you have it very close, then I finished it using a ratchet, but being very careful to monitor how much it takes to pull it together. It shouldn't take much torque at all, or something isn't right. Putting the trans back in place and torquing the bolts took about an hour doing it this way. I would definitely figure out a way to reach up in the bell housing area and cut that ear off BEFORE I try and remove another trans that still has the mounting tab. Its purpose is done, get rid of it and make life easy. It should be possible to make up a long tool to reach it with a hacksaw blade attached. It will take a while to cut off, but not near as long as fighting the trans to get it out.
