Interesting scenario, curious if a trans flush may have had an effect but its out now. Maybe they'll find a plugged passage etc.
I personally think a powered flush would do as much harm as good. Cycling it through per several threads on Mud might be ok, but I understand the solenoids are highly magnetic and any high pressure disturbance could move metal from a harmless place to somewhere more critical.

I have wondered if a few of the one’s we have seen go bad weren’t partially caused by extreme power flushes down by several Toyota dealers ~20 years ago. There were multiple companies that built machines for service departments to use that pushed fluid through at far greater pressure than T intended.

I should stop here, I will get well past my engineering and mechanical pay grade very quickly.

There are several good threads on transmission flushes buried in the 80 series archives.
 
FWIW this might a good place to link these videos from Wholesale Automatics
showing what they find as they tear down automatic transmissions with various problems. . Couldn't find a 80 series transmission video done by them (yet) but they said they're making a set of videos called "What Went Wrong?" so an 80 series specific video might show up in the future.

I think that society in general greatly undervalues the wisdom of tinkerers, custom builders and those who repair things for a living over someone with an engineering degree. I’ve worked around many different minds included engineers who didn’t know how a bubble level worked. Some smart ones as well.

Real world experience with repairing components brings to light flaws, weaknesses and the weird events, materials or synergy between components that cause failure. A mind smart enough to find the damage, cause of damage, and analyze how to build things better is very valuable, regardless if they are paid to that value or not and it’s the opinion we should probably take seriously. You shouldn’t dismiss your practical thinking on this matter either.

I’m not sure who the transmission guru is for this application, but I’d be trying to hunt them down. Maybe an old transmission shop in Australia that specializes in cruisers would be a best target to consult.

I could not find a reputable transmission guru that was willing to tackle a rebuild, I even sent a few emails to very reputable manual Toyota transmission specialists across the country.

I ended up putting 2 different used transmissions in one truck to find a very good one. I did eventually find a NOS transmission in a parts department in Texas to have in reserve in case I needed another one!
 
I sent out the transmission to get rebuilt and when I received the transmission I had learned that the second coast brake piston had been pulled out then pushed back in when that happened the reverse belt had fell off the track and when put back in the belt broke after 10 feet. after I had reinstalled the rebuilt transmission the car now has no gears no reverse no drive and no park, the car is now going to be towed to the transmission shop that had done all the work to pull the transmission back out and see if it is something in the install process that caused the issue and they will finish the Toyota there. I'm glad to have the thing out of my shop but unfortunately I will more then likely not know the reason for the second failure if I do learn the reason I will respond to this post and say with it is
