Peugeot 307 Automatic Gear Problem

I have a 2006 model 1.6 xt 307 with automatic transmission. I bought it in February last year.

I do not understand the car very well, let me state it first.

About 3 months until the engine of the car is warmed up. It locks the 3rd gear, and when I switch it to manual mode, only D is displayed. Snow and sports mode does not warn. When I pull it to the right, turn off the ignition and turn it on again, my problem was over, but for the last 3 days, it has not improved on it either. Since there was no heavy traffic and traffic lights where I live, I had no problems with the other gears. Only once did I do a lot of stop and go, then when I was going from 1 to 2, someone from the back made a continuous knock as if it had been hit. The road I used to go to work is a bit too ramp and now it started to strike from the back while climbing. I took it to the nearest pejo service, we do not understand the automatic transmission, but they looked at the error code to learn what it was saying, "The pressure regulation advice is not characterized". He puts the speed forward and brings it back to normal. For example, I go with 50 to 60, the speed suddenly becomes 5000, the engine screams, but if I step on the gas, it does not accelerate, then it returns to its normal speed and accelerates itself. I bought gas from a place that I do not trust much, I don't know if it has anything to do with it.

I will go to Istanbul next week, can you suggest a good master who can solve this problem. Thank you very much for your help in advance.

(You have such a problem for 3 months, you will ask why you waited, I know I am a healthcare staff and our leave was closed for a certain reason, it was just opened. I had to leave the vehicle for at least 3 days, but I could only go to work, my own vehicle

Also, do I have a phone number or full address that I can reach :)

Not exactly, mine was a little better;)

I hope your problem will be fixed with the most inexpensive solution.

Master, I was having the same problem as in the first message. Today, when you saw this message, I also changed the piece you said. The car ran properly for an hour. Then he did it again.

The gearbox has also seen a revision in its previous owner. But there was an oil leak etc. I changed the oil yesterday with the appropriate oil. The fan is also connected to the 2nd stage. I've ruled out other possibilities as well, as you can see. This was the only thing left. It didn't happen again. I still use the car in snow mode.

Hello. Is it Estağfurullah? You know, we are trying every way to solve the problem. It's not an expense. After all, nothing went into the air. Part of our vehicle has been renewed. Now, at least, that piece of possibility doesn't remain in my mind.

They made the setting you said. But you said that there should be a sound in the r and d positions of the measuring device, and no sound should be heard in the n position. The master also says that it must be the opposite. When the sound is heard in the N position, the assembly is completed. He said that the device should not sit in the R and D positions.

I think I need to focus more on the cooling system.

I wrote on the other topic, I'll write it here, I'm in Istanbul, I had the number of the master in maslak industry, but the phone was faulty, I didn't save it in the google directory, check the number on the new phone. I searched but couldn't find it. If I can reach you, I will send you his number or if you are in Istanbul, I can direct you to him. Believe me, I don't know if this setting is correct, I don't know what the master told me when I asked him, maybe he told me wrong, maybe I misunderstood, I don't know but I'm sure he said it this way, other than that, I had the radio and hoses completely cleaned before this part was changed, but my problem was after this part was changed. then it was fixed.
