I had previously reported my Powershift hanging on to over 3000rpm in first and second even under very light throttle. Very annoying in slow traffic.
Well, the upshot of this is that I had some warranty work that needed to be done (replace sump due to oil leak and new door lock to activate interior light) Also reported slight surging when driving.
Dealer reset onboard computer and what a difference! 1st now shifts at +/- 2000rpm and 2nd about the same. This has made it a treat to drive especially in slow stop/start traffic.
So any Fiesta owners out there who have the same problem a reset will cure it and the box will shift with low revs at low throttle openings.
