 2014 ford focus, had the clutches replaced in 2015 and still shudders. Got a lawyer and filed a lemon law .....got a settlement from ford and now they have extended the trans warranty to 10,000 miles. Just took it in for a TCM update as per the letter from ford  (transmission control module) service adviser told me it will never be perfect but it will help. Even with the new clutches last summer it was shuddering again, what a piece of junk.
