306 Automatic Transmission - Can you help?

Hello friends I bought a new Peugeot 306. It is a 2000 model 1.6 XR HB transmission has been newly overhauled. 80 thousand money was spent and another transmission shop checked and confirmed that the transmission was new. There is no problem when the car is cold in the morning. But after 20 minutes of warming up, there is a knocking when shifting to 1st-2nd and when dropping to 2nd-1st while braking and stopping. This is sometimes very little, sometimes not. They say this is normal for AL4s and that the transmission will get used to it and decrease with use. Is it true? Today the car went into neutral twice while in d at the traffic lights. I mean, I gave gas and it didn't go, but it detected it and continued. The position sensor has recently been changed. Is it normal? Your comments are important to me, can you please help.

There has been no sound from the entire group for two months.

Hello Mr. Muhsin, I also own a 2000 model 1.6 automatic car. The issues you described happened to me as well. Occasionally, when shifting into reverse, there was a very distinct knocking sound. When I showed it to a mechanic in Umraniye, he said that these are normal knocking sounds with the AL4 transmission. Later, after some time, when I braked and was about to come to a complete stop, there was a clicking sound coming from the gearbox, like shifting from 2nd to 1st gear. If you have done anything to solve this, we would appreciate it if you could inform us.
