BMW driver question
When changing gears (the worst is from 1 to 2 a little better from 2 to 3) there is a strange noise from the chassis as if the rear part (maybe the shaft support) and unfortunately jerks. As I try to change gears very gently, I almost succeed, there is no way to change quickly. Higher gears from 3rd to 4th and 5th shift just OK. Reducing from higher to lower does not happen smoothly either. Please give me a hint.
