I have read that it can be difficult to shift the Crosstrek 6 speed without avoiding some lurching and jerking motions. Even though I have been driving manual transmissions for over 50 years, I had the same problem with my new Crosstrek at first. It now has over 4000 miles on it and it is no longer an issue. I'm not sure if I have finally developed the skill and tecnique, or if the clutch just needed to break in. What has been others experience with this?
