Unfortunately, I did not get a complete response even though I wrote in various titles. So I will summarize the latest situation and ask my question under this heading: STATUS: - My car is 2006 model, t (r) iptonic gear, 307 SW. I bought it year. My previous vehicle was 2005 307. There were no jolts in his gear shifts. But since I bought this vehicle, there has been a jerk in gear shifts. - The car has been giving "GEARBOX FAULTY" error within 5 minutes after the new departure for about 2-3 months since the weather has cooled down. So "Transmission error". I investigated, it was said that this was fixed by changing solenoid valves.- I had my car connected to the computer, it gave pressure adjustment failure, the transmission had problems with oil pressure. (Error Code: P1701) I changed the gearbox oil, there was no improvement. MY QUESTIONS: 1- The 3 problems I mentioned above are the things showing the solenoid valve malfunction. Many people say that they are experiencing these problems, and they have solved this problem with the solenoid valve replacement. But my solenoid valves are new type. Although it is a new type, can it be damaged? In the 307s of 2005 and before, new solenoids were introduced with the software in solenoid changes. 3-4 or 4-5 months ago, I changed the gearbox oil. Do I need to change the complete transmission oil again during the solenoid replacement, or should I just add an additional? http://www.peugeotmarket.com/ELEKTROVANASELENOIDTUM-MODELLER,PR-2.htmlI would be pleased if you could reply the item. quantum2012-12-19 10:26:33
