2009 x164 - GL450 - Correct transmission oil fill level?
I can't find any information about proper trans fill level.

There is no transmission dipstick

I have the Mercedes books in front of me:
Maintenance Booklet:
No mention of fill level
GL Operators Manual
No mention of fill level beyond this "if the trans is leaking, take it to the dealer"
Is there a useful DIY link somewhere?
I really miss dipsticks!
