[BMW335l]

Hi, I just bought a 530xd 03/2007 lci (it got the new silver gear shifter). Which gearbox is in my car. I know that the 530d lci got the upgraded zf gearbox rated at 700nm. But I also read that the 530xd still got the old one rated at 600nm. What is true and which one does my car have?

Thanks.
