307 automatic shifting from 1st gear to 2nd gear knock

I have an automatic peugeot 307 1.6. The vehicle makes knock problems when shifting from 1st gear to 2nd gear. as if something squeezes the car, then leaves it. sometimes sound comes out of the gearbox. sometimes if I come across a bump or something during the transition, something is touching somewhere as if something is shaking at the bottom. What could be the reason for this? I do not want to touch someone who does not know the job, since the vehicle's gearbox has never been touched before.

Find and show an experienced service in the automatic transmission automatically. Usual problems in Al4 gearboxes.

Engine wedges look first at the transmission ears. I had the same problem. The transmission ear was gone and I took it for 50 liras.

What is the km of your vehicle?
