Why the heck would Ford change something that wasn't broke!? Frustrating for sure. I can only imagine it was a way to save a few bucks.......
I have the same "new style" connection on my 6r100, located on the drivers side.

Right off, he said the new design will flow better through a bend vs the banjo-style connection. More torque = more heat in the transmission. So I think we see why the cooler moved, and the lines changed...its an effort to improve trans cooling. If more fluid can flow through the cooler than it will cool down the trans better.
However, he did say the old style appeared to be better at holding down the lines. I assumed the flat plate on the 2017 would flex more...but he said the 2016 bent design would actually be longer and some strength was lost by the metal fracturing as it was bent. Nevertheless, the banjo design appears to hold in place better.
So maybe not cost cutting after all, maybe a performance improvement, just need a way to keep the connections tighter.

And I think I have the answer, after talking to one of our engineers.

I don't recall over heating problems in the past that could have been associated to this clamp though.

You don't have to have a problem to improve something. Usually it works but sometimes it doesn't.

They may have used the same hold-down clamp to standardize parts and save money.

Perfect, thanks RainDesert. It appears to be the identical hold-down plate, although it is mounted in reverse on this transmission.
Which side of the transmission are these lines on? Drivers or passengers? I'm guessing drivers because the shifter cable is usually on this side...

The connection is on drivers side. The lines come from the cooler along the passenger side, then 90 just past the bell housing, under the tranny. Then come up on the driver side, and to the connection in my picture.

Great info, thanks! Reps sent.
RainDesert, on the diesel, the tranny cooler lines are on the passenger side. Interesting. But looking at the statement lts just posted, it looks like you are exempt from the problem!

Maybe I dodged that bullet then. . . my build date was 11/4?

Update: Picking Truck up in a few with new part installed with old bolt and washers.
Was able to get part installed with old washers. Dealer was not aware of bolt and washer info until I sent a screenshot of this site. Bolt and Washer are on order and I will run back up there to have them installed once they come in. The line is currently not leaking with new part and should hold for shuttling around town for a few days while bolt and washer are delivered. The picture of that document is key, check bolt and washer #'s.

They replace lines, washer, and bolt. Take a screenshot of that SSM posted and they'll know exactly what to do.
