208 transmission knock

Hello dear Peugeot enthusiasts, I am new among you, unfortunately my first message will be a cry for help. My 2014 model Peugeot 1.4 HDİ automatic transmission has a problem that drives me crazy and makes me punch the steering wheel constantly. I bought this car second hand at 175,000, and when it reached 177,000, the transmission started knocking terribly. I tested it and drove for distance, and when I got to 30-40 km, I suddenly hear a "beep beep beep" sound and it won't shift from 1st to 2nd. It rocks back and forth enough to shake the car, locks and stalls (sometimes it doesn't, but it doesn't shift at all, it just rattles in the middle of the road and beats enough to throw us around, and it continues one by one, so I pull over to the right and keep coming back). I put it aside, park it, whatever the hell it is, and start using it the next day. It's fine until I reach 30-40 km, but then suddenly the same thing happens again, and the cycle continues. I've practically driven the car from store to store, and my daily limit is worse than a horse-drawn carriage. The mechanics aren't saying anything right. Some say it's the robot, some say it's the oil, some say it's chronic and there's nothing to fix. So, I'm stuck with the car. What's the problem? If anyone has experienced this before, I'd love to hear from you. Please respond. I can't go to work, my kids can't go to school... sfkpejo2024-09-19 23:07:14
