BMW E90 335i Xdrive 8HP45 swap

Hello I'm currently gathering information on what I need for 8HP45.

Mechanical part:
Transmission and around it everything fits perfectly.

Electronic part:
Need to resolder TCU with this simple PCB:
https://www.ebay.com.au/itm/14428831...=20012&mkevt=1

Also need F30/F10 BMW gearbox switcher, since E90 doesnt fit and wiring mismatch.

Also saw lots of on youtube that there is: https://www.ebay.com.au/itm/33485447...Bk9SR4zJvLzvYg this one transmission "brains", but problem I dont see available in eastern europe is there other possibilities for these "brains"?

Oh and oil cooling lines doesnt fit also couple mm differences.

Is there anything else I should be aware of?
