My car is pretty new and PML has diagnosed that I need to replace the transmission as the way the car drives is not "right". Something about the adaptation going off. I have dug the internet to find out more about the ZF transmission and it seems that the electronics that controls the hydraulics that does the gear shifting is all house within the transmission body itself. I don't really want to share the details but suffice to say my SA is very helpful. Has anyone had this done to his car?
