Renault India — Duster AMT RXZ shuddering

I own a duster diesel AMT from 2019 .From the very beginning, I was experiencing shuddering issues during N to 1 to 2 gear infrequently. But after clocking 16k km the issue was very frequent and very irritating especially during the heavy traffic. When i reported this issue to the service dealer, they replaced the clutch as vehicle was under warranty. After replacing the clutch, I again started experiencing the similar issue less frequently though .When I reported this the service dealer every time they were saying that they have checked the gearbox and ensured its working fine.Now i hav clocked around 58 k km, still i am experiencing the issue now more frequentky especially during heavy traffic time.I have left my vehicle for periodic service now, the service dealer is saying the flywheel has to be changed to stop the issue.Now the vehicle is out of warranty and it is costing a bomb.Kindly resolve this issue.
