Clunk noise and sudden movement of transmission

Hello, the vehicle's engine is working perfectly but when the gear lever is moved from park to reverse, one will hear a sudden clunk noise and sudden movement of the vehicle. I scanned the vehicle but I couldn't find any codes on the transmission. I have replaced the engine and transmission mount but the problem persist. I have replaced the CV shaft on both sides (complete ). I also changed transmission oil and replaced the filter but the problem still persist.
When the gear lever stick is moved from park to reverse it will clunk suddenly but when it moved from reverse to drive it won't occurred, when moved from drive to park it will not occurred. Moving it from park to reverse again it will occurred.
