Note: for the post face lift e53 you need special snake oil which you can get at the dealer or ECS tuning. Also, once you flush the TC on the x-drive you need to reset the adaptation values in the computer. A search on here will disclose the procedure.

I just got some fluid for the TC and the gear box but haven't done the fluid change yet.
