The Focus and Fiesta dry clutch powershift transmissions are Getrag 6DCT250 while the Mondeo wet clutch units are 6DCT450. The 6DCT250 uses all electric actuation. The 6DTC450 uses hydraulic pressure controlled by electric solenoids. The 6DCT450 can be locked manually with the stick.
There were problems with the 6DCT250. I suspect that's partly why powershift has a bad reputation.
