I am trying to change the sop called lifetime fluid on an E39 1998 B10 4.6 Alpina.

My car is on ramps and I have searched the archives on the e39 board etc.. but I cant seem to locate the drain and fill holes.
Someone-I think Laszlo sent me a link with a write up but dont know where it is.

I have seen the small screw/allen key at the bottom of the transmission pan and I can see a hex key possible fill hole at the side on the rear passenger side just above the pan but where can the fill hole be?

Somewhere I seem to have read that the fill hole is at the front about 3" above the pan and its a 16 or 17 mm nut. Is that correct?
