Trans rebuild is underway, housing stripped:
Rear sprag was starting to tear its way out of the housing, which is a known weak point in an otherwise bulletproof auto.
Bolt in sprag going in:
A shift kit is also going in along with some mods to valve body to firm shifts up. Converter is also having a going over, when done she'll be all good.
With $$ as it is, have some bits on order from US. Maybe some shiny alloy bits.
