I just purchased a 1LT Cruze Automatic transmission with 279 miles on it, and had a couple questions about the car. The transmission seemed kinda jerky. When taking off from a stop, and when it shifted gears, it seemed to jerk quite a bit. Is this because it's new or is that the way it's gonna be forever? Also, I noticed that for braking i had to push the pedal down pretty far before it started to slow the car down, and when it did, it seemed to brake very hard after a certain amount of pedal depression. Is this because the brakes need to be worn in? Thanks for the help.
