As you've already replaced the transmission, the problem might be with the tranny computer or speed sensor. I would just bring it to the BMW dealer to have them hook up the computer and decypher what's wrong.

I second that. your going to need them to read out the error codes your car's obc is spitting out.

I don't think you needed to replace the tranny.
