Motorcraft Dual Clutch Transmission Fluid is specifically formulated for use in the DPS6 Power Shift twin dry-clutch transmission. It was designed as dual functioning fluid to protect gear, synchronizers and bearings, while also used to operate the transmission's shift mechanisms.
I just wanted to write a review here, so that if someone is in my position and is looking for the correct fluid, here it is. I've seen on the Fiesta forums that people have used different types of gear oil, and while it might work fine, this is the correct oil according to the Fiesta ST supplemental owners manual. It is available online from Ford for free. This is the oil that states in that owners manual that must be used, and it will take 1.8 quarts, so you need to buy two of these. I haven't changed my oil out yet but it seems to use a hex/triple square bolt, so make sure you have a set of those on hand, and make sure you take out the filler bolt first before the you do the drainage bolt. That's all there is too it really, get some sort of a hand pump or something to put the new fluid in and you're good to go. If your Fiesta hasn't had a fluid change in the first 10k miles I would definitely recommend it, because it's breaking in and there are going to be a ton of metal shavings in it. It wouldn't hurt to get a magnetized drain plug as well, so you can pull out even more shavings.
My 2014 Ford Fiesta ST uses XT-11-QDC dual clutch transmission fluid. The issue arises with the specification that is called for. Both my manual and supplemental manual note the XT-11-QDC must meet spec WSS-M2C200-D2. All the oil, including this offering according to its back label, meets specification WSD-M2C200-D2 rather than WSS-M2C200-D2. I visited the Ford Chemical and Lubricants website and they do not even list the fluid with a WSD prefix, only the WSS prefix. I had a difficult time finding out what the difference between the two may be, and I was finally given a partial answer. The WSD is 75W90 weight oil, while the WSS is 75W80 weight oil. There may be other differences as well.
