ATF fill hole location 540 A5S560Z trans???

[prossi]

Bentley shows a picture of every other e34 trans fill hole but the one for the 540. It states the level should be 'spilling out' of the hole. I see the drain hole at the rear lower corner, but don't see a fill hole. Please help me out and point it out to me. Thanks.

ps the trans didn't leak prior to storage but lost about 1/2 qt while sitting there. what would cause this? converter seal?

thanks
