Inspection of a 904 torqueflite
I see what you mean now.

When I drag a fingernail across them. All they do is go smooth.
It doesn’t seem like they dug in at all. I found some pictures of what you mean as well. These don’t look like they are damaged in any way
From what I can tell the planets and the sun gear, torque converter and bushing have taken the most damage.
Also.....that ring gear on the clutch spline side is worn just on the bottom part.
The helical gear on the other side.....no damage at all
I’m also wondering about that output shaft support.
I’ve looked on eBay for some used parts. Found sets of them for sale for reasonable. I do not know if they will fit what I have.....and I mean as a set. If I go to a smaller sun gear with matching shell and planets as a set. Will the newer transmission parts fit into my older case. The one in the picture of the set for sale that show it to be a lower gear set. That doesn’t matter to me. I just want good parts that fit.
There is no pitting in any of the parts. Just the crowns ground down some. What ever did that didn’t touch the planets matching ring gear.
Another question. This forward set has the waffle textured friction plates. Was that standard? The direct drum has smooth textured frictions.
This transmission didn’t make a sound. Shifted perfect and smooth before I took it out.
