This has been the only guy to even entertain on helping me. Everyone else has just NO cant do it! It's something to look at for those who maybe have shop like ABR or Sammy. He states that the x5 uses the same hp21 but being that it's a SUV good chance it might work as it's been mentioned before.

Any place the N54 is used will provide a good swap, unfortunately the X5 with N54 also uses the 6HP21. I’m not knowledgeable with BMW bell housing to block configurations. Check if the shape of the bell for a N54 is the same as other larger engines. If yes you may be able to use that model 6HP28 transmission.. The mechatronics from a 6HP21 will bolt to a 28 as long as the 28 does not use a electronic park control or shift by wire setup. As for the software your on your own, can’t provide any help as nothing has been configured to do what you are attempting.
