Okay, The plastic piece may look very confusing, but in order for it to fit in the transmission.

Remember, I've not started to assemble mine yet! When I get to that portion it will be 100% clear.Since I did take lots of pictures with a High-Resolution camera mounted on a tripod I can see many things in fine detail.

So here goes:

You have to look at the posts where we were talking about EPC, and I uploaded the Mercedes file with the line drawings and part numbers. Take a look at the drawing that has parts 60-64, and the plastic finger part is part 127. Mercedes calls the clutch pack "outer disk", and ATSG calls the clutch pack "Brake B3" for reference.

Looking at the plastic finger piece, the middle finger has an alignment tab on the other side that runs the length of the finger for the most part. The tab faces down in the deep rectangular opening in the case, and the tab is closer to the left of the opening(look at picture 4277). Do note the fingers point facing the rear of the transmission(note picture 4278, and my grip with the pliers in both pictures) Remember, the "outer disk" clutch pack needs to be in place(parts 60-64) need to be in place for the finger plastic piece to fit. Plus, you will see the openings in the case where it will fit as you can see it in picture 4288 where it was removed from.

I hope this will clarify the mystery of the three-finger plastic piece.
