Hi guys. Quick question. I would like to change the gearbox on my Audi. It's Stronic 0CK. I found one on eBay from Audi A4 2020 0CK301103. Looking exactly like mine. After oil change and adaptation the gearbox changing gears weird and is not smooth anymore. Also I found there is a lot of play / loose in the mechanical part of my gearbox. After swap do I need do any coding ? Or it's just swap like for like? Thanks for help
