Hi Richard, ZF recon it is the 5HP25 Either way, the ZF 5 speed HP range use the same fluid - confirmed by ZF GB. They also say that it is that old, not even they keep it anymore - all new stuff is Shell for 6 speed and above. Can't find it at ECP. I'm happy to go to BMW especially at £8 less than OPC
