Never said that's why I thought it was a DCT. I just thought they were mating the wet clutch DCT to the 1.6L across the board. I never looked it up, my mistake.

I'm even more impressed then that it performed as well as it did. Though, like you said in the statement below, it only has 100 miles on it so of course it should be working pretty well... for now I suppose.

AX4N and 4F50Ns that lost the pump shaft between the torque converter and the transmission, ergo no forward drive. Pretty much every FWD torque converter auto they made has or will fail before it was expected to. On the proving grounds at an SAE conference last year a 2011 Fusion with the 2.5L i4 and the 6F35 was suffering a hard engagement into first and felt like it was slipping and eventually overheated. I had to move forward a few feet to get into position to launch the car, came to a stop, then when I rolled into the throttle when given the clear to go it failed to move right away. It then hit first gear hard and chirped the tires when I had not tried to do so.

However my grandfather's 2009 Mariner with the same powertrain hasn't had any issues yet, but he only has around 22-25k miles and most of the ones that have failed had between 106-114k miles.

The 6F55 has a higher torque capacity and might be more durable, but the 6F35 is not as durable due to the lower torque capacity.

I so far prefer the DPS6 DCT in my Focus over the 6F35 for anything with less than 2.0L of displacement. If the Escape used even a wet clutch version of a DCT it would be preferrable to me over the 6F35, but I understand why they went with the 6F35, it just creeps better due to the fluid coupling/ torque converter and feels more conventional.
Interesting background, thanks for the info. I now remember where I have heard about this trans before, as I had a buddy who owned a Fusion and he experienced said issues.

They didn't use the wet-clutch DCT, I would assume, because the bean counters stepped in just like they did with the dry-clutch DCT decision for our Focus.
