308 1.6 hdi

Hello everyone, 1) My 2011 308 1.6 HDI automatic has 207,000 km and is making a knocking noise when shifting gears. This started happening after the pressure plate was replaced. Could there be a problem with the transmission fluid or its coding? 2) When I lift my foot off the gas in traffic, the vehicle jerks forward. I've replaced the engine and transmission mounts, but they still haven't resolved the issue. Could the problem be with the transmission? Is there a competent, God-fearing mechanic in Samsun? I've been dealing with these problems since I bought them, and I'm driving myself crazy. Regards.

You can solve the problem. Can you write here? I have the same problem. No matter how many technicians I went to, they all say something different. We can't get close to the service anyway.
