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.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 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.
