Hello, I became the owner of my 2013 model 5008 vehicle while driving on the road, the automatic transmission was canceled and my vehicle could only be used as a manual gear, besides, while the rpm could exceed 3000 in the first three gears, the rpm could not exceed 2000 in 4 5 6, so the vehicle turned itself off in a way. No matter how hard I tried, even if I turned it on and off, the fault did not go away, I read many articles in the forums, some of them were writing three times on and off, some of them were saying that by removing the terminal of the battery and plugging it. I had the car connected to the computer. There was no obvious transmission malfunction in the car. Looking at other issues, there was a malfunction saying that your particulate filter needs to be changed. I went to the industry in Ümraniye and could not get any help from the tradesmen there. Those who say let's clean it for 600, those who say the liquid is gone, let's change it to 1200, everyone is taking it out, and those who say we can fix it for 650. I did not trust any of them. I went to Kadosan Industry and asked if there was a reliable tradesman there. They told me about SRT OTO serhat. He said that the fluid connected to the filter might have run out, he completed the fluid, then computer celebrations were held and after these adjustments and corrections, my vehicle's transmission malfunction was also resolved. When the liquid ran out, the vehicle protected itself. In total, I was done for 600 TL including liquid. Citroen Peugeot is a complete competent and very trustworthy person in the field of vehicles. While doing the job, he tells you the event and gives you information. I gave the right without any bargaining. After that I found my master. I advise.
