GEARBOX FILLER PLUG REMOVAL TOOL SIZE.

[Dunkeld]

I am busy doing a fluid service on my 1998 BMW Z3 2.8 Roadster and have hit a snag. The Engine oil and rear diff fuid changes were no problem however when I looked at the Gearbox filler plug it looked like it would require a special tool/socket to remove it. I would be grateful if someone could tell me which size of tool/socket I need to do the job.. Many thanks..

Panic over. The drain plug is 17mm and is on the other side of the gearbox housing (drivers side) to where I was looking. Strange though as the thing I was looking at with the torx centre looks also to be a drain plug. Many thanks. No further assistance required.
