63 Dart 904 with rear pump thrust washer question

So I took pictures but cant find my cable to transfer them from camera to computer. ouch. I will post them when I find the cable.

I am using assembly grease to hold the washers in place.

I fiddled around today with the tranny and put the third tanged washer between the low reverse band drum and the rear annulus gear support even though there are no holes to anchor the thrust washer. But I noticed that between the driving shell and the rear planetary gear assy there was still lots of end play movement ~.25"so it sure seems that the thrust washer should fit in there somewhere.

From the diagrams I have in my service manual and the ones I see online it looks like the planet gears have a thrust washer with 3 tangs each, that accounts for two. If I place one of the tanged thrust washers behind the rear planetary gear (where there are places for the tangs to fit) it pushes out the whole assembly from the drum leaving some of the planetary gears sticking out. But by pushing on the whole assembly I am able to move it back and forth a considerable distance and it seems to slip into place but I am not sure at this time.

From the way I had the parts laid out when I disassembled it looked like there were two thrust washers together but I cant make two of them fit together because the tangs wont fit over the other washer so this doesn't seem to be it.

The only planetary gear assy that is disassembled is the rear one, the front comes off as a unit still inside the annulus since there is a circlip holding it together. I assume there is another thrust washer in that assy so it is not missing.

Seems like it should be so dang simple.

Kicking myself in the ash.
