Overall, that TH400 saw high-heat and probably burnt frictions from lost pressure due to low fluid level.
Lo-roller roller springs lost their tension from heat, lightly stretch them each and reuse. They can break from over stretching.
Dir hub (Int) sprag and it cage are suspect: the dogbones are rarely (like never for my experience) able to fall out. Can test 1-way action and visually inspect remaining tilt for reuse.
New steels (or 320 grit scrub followed by 0000 steel wool scrub) to replace scored steels. I didnt study the friction images.
Re-check: sungear shaft clearance with Center-support babbit bushing. Imperceptible clearance/movement or is it bad with 0.005-0.015" slop?
What was valvebody? GM?
