Got the update today. The dealer I went to was really cool about it, and even shuttled me to work which was really appreciated.
Backing up a step, I simply called the dealer on Friday to set up the appointment today. I had simply said I didn't want to waste my time with the whole "this DCT is different" business, and simply wanted the update. The service advisor initially said, "That internet news stuff is bull crap," as he couldn't find the update for a minute. When it showed, he said, "There it is." and said to go ahead and set up the appointment. Today, after the update, I took the car on a 20-25 mile trip around Tampa Bay, with 90% highway miles, 10% city. Here's some of the areas I evaluated, and what I thought:
Shuddering at lights:
Still there, but less prominent. A lot smoother than before, though. Car however has more willingness to crawl up to a light without an accelerator press.
Crawling in R:
Better response, don't need to press the accelerator as much to give my car that go to go backwards.
Responsiveness in D while at speed:
Way better. I no longer feel like I'm struggling up hills as the car is more willing to downshift on a press of the accelerator than it was before. Excellent when keeping up with traffic on an uphill.
Responsiveness in D while from a stop:
Way better. Will maintain lower gears longer, and will drop fast when the car detects a maintained speed.
Smoothness of shifts:
Better. The car is quite smooth as silk now while upshifting. An occasional torque-converter like shift while going from 1st to 2nd but again, way better than the full-clunk which I got more often before the update. I'm thinking after the "adjustment period" this will get even better.
Still same amount of delay while shifting manually up/down gears. No improvement here.
Less clunky on full throttle, but I still need to do more testing with the car in S. Still will keep gears longer than D.
38.2 MPG @ 55-65 MPH on a 20-25 mile loop on mainly level ground with small hills, including some a couple of stoplights. That included several full throttles to merge, and better use of the lower gears while passing. Can feather the accelerator more skillfully now. Glad I can keep the same fuel economy.
Overall Grade: A better car with an hour update. The car really has some zip now. It was worth it. Thank you, Ford!
