07 s550 filling transmission question
A pic of the transmission
I’ve enclosed a pic of the transmission.
I know the transmission do not have dipsticks.
But from the pic, where would You add some fluid?
the black plastic plug? Or is it the tan colored plug?

I see that
I have watched all the YouTube videos. They show that there is a place to put the dipstick. But all the videos show a locking cap. The pic I uploaded is the same as the tranny in my car. No place to put in the dipstick. So I was wondering if the black cap or the tan colored plug is where the locking cap is supposed to be?

I don't believe there is a place for a dipstick on the 722.9 transmissions, whereas there definitely is a dipstick tube on the 722.6 (5 speed). The 722.6 was only used for the S63 and S65 in the W221 chassis.
So for a 2007 S550, you would have a 722.9 (no dipstick) transmission which in order to fill correctly must be filled from the drain plug at a given temperature measured by the transmission internal temperature indicator.
