Regarding that rusty shaft, to my surprise, just blasting the rust off with a rotary steel wire brush was enough to get it to go through. For reference, some 30-odd solid hits with a 2# dead blow would only get it about halfway through yesterday.
I disassembled and reassembled both pumps and the planetary assembly today. Both pumps were in great shape and within tolerance, but I found some broken parts in the planetary assembly area. Specifically one of the low band mounts and one of the damper leaf springs for the ring gear. How common is it for these things to break? It's hard to imagine the low band mount receiving too much stress unless maybe there was tons of engine flare in the high to low shifts? The leaf spring I would assume is just normal fatigue.
I noticed the gearset to have a significant amount of flash rusting in various places. Which I ignored... 🙈 I also found a significant amount of what I could most closely describe as dried aluminum anti sieze under the thin metal plate on the planetary assembly. Is that normal? I can't think of why such a thing would end up there, even from wear. It was metallicy gray colored paste essentially.
