Hello. I have a problem with my MB Cla 220 CDI 2013y automatic transimission. When car is standing and i put it in D or R it starts to shake. I have buy in MB and changeboth motor holders but problem is still here. In N or P is better and car is not shaking so much. But when i put in D or R i feel push and car is shaking. When i start to drive car everything is ok again. Doesnt metter if car is cold or warm, all the time is shaking in D and R. What do you think what can cause this problems?
