Hello, I have a 2011 model 308 1.6 VTI automatic gasoline vehicle. I bought it 3 months ago. For the past month, we've been having this problem. After starting the car, it makes a knocking noise when shifting from 1st to 2nd gear for 20-30 minutes at stop-and-go traffic lights. The tachometer rises, passes 3rd, and then suddenly shifts sharply to 2nd. We just changed the transmission fluid. They said it might be due to that, but nothing has changed. Can you help me with this? I'm sure someone else has had the same problem. Thanks, Kingoo2023-10-09 17:08:59
