Programming a replacement tranny.

Question by conradr.blease posted 6 months 2 weeks ago in BMW

Hi,<br />
<br />
What BMW "coder" would I need to code a replacement transmission on my 2007 335i.<br />
In other words if I install a used but otherwise same transmission, how do I code it to work with the car?<br />
<br />
-Thank You
