Update: After clutch replacement my DCT was shifting a little erratically. Then i took it out back and did the ole' 5 hard accelerations. Worked like a charm. This is the 2nd time this has worked for me folks, so try it for yourselves. The DCT has been very well behaved in the week or so since.
That, plus the elimination of most rattles (rocks on the brake lines, and realizing that the HVAC vent louvers rattle in certain positions only and is therefore easily fixed) make me a relatively happy boy with my Focus. Almost 11k miles on the clock now.
