Hello friends, I have encountered a problem again and hopefully, as you have solved my last problem, we will solve this as well. The vehicle 206 1.4 Xr AUTOMATIC 2001 model and 84.000 km, while I was driving with this vehicle, I stopped at traffic lights and drew my gear from the brake position, I dumped my foot, the vehicle wasted back, and I did not put on the gear. He made a knock between 3500-4000 rpm and switched to gear 1. He made this problem several times during the day. There was no problem. I did nothing, what is wrong with you and how can I solve it? What does it cost? Please help friends, thank you very much in advance.
