This is a gearbox from another car:

I found a gearbox with the same block from the same car, but the code on the valve body matches and I also think it won’t match on the board (it’s not visible because it’s not disassembled)
What do you recommend on how to check? And will there be one more thing that needs to be programmed after the replacement?
I also have a question: are all the transmissions on these cars 8 speed or are there 9 speed ones?
