I guess I will need to attempt to do this retrofit, since not much people have done this and I will be able to tell if it was worth it or not. If it would improve kick-down once you step on the gas pedal while cruising that would be well worth it for me. As I really hate that lag. Faster manual shifting is also welcome.

Maybe thats because I have found 6HP21 from 2010 E90 320i N43.

Does 6HP21 from any engine is ok? 116i/120i/320i from N43/N46?

Or I must use 6HP21 323i/325i/328i/330i from N52 only?
If so its much harder to find, I find only old gearboxes of 2006 or similar...

P.S. Interesting find that in Europe E92 N52 had GM GA6L45R gearbox not ZF:
