06 530I transmission replacement

[sprinter1w]

Has anyone had any success with a used transmission? I understand the mechatronics is married to the car and would have to be swamped over. My concern is would I be able to scan and install any new updates if I were to install a used transmission? Any help would be appreciated. Thanks in advance.

I'm curious why you are changing out the tranny?

If it is doing the wacky shifting/surging thing, the solution seems to be rebuilding the mechatronic valve body. I know of a company that sells rebuilt units with 2? year warranty for $1400.

If your whole tranny is toast, I would rebuild the valve body as part of the swap anyway, so I say rebuild and test with existing tranny. Then buy a replacement if your is truly crapped out.

Yea I forget what year they did the married to the car thing, but for those cars you cant use a used trans.
