I don't think it would take very long to filter all the fluid. IF the cooler flow rate is 2GPM and there is 3 gallons in the trans, you would run everything through in about a minute and a half.
Well, there is fluid trapped in areas of the valve body and such that would require going through all the gears, but say 90% of the fluid would be be run through the filter in just a few minutes of idling.
I think you are exaggerating the flow rate.
Besides what is the efficiency of the Magnefine? I think the paper element may he 10-micron.
Your drainplug also likely has a magnet which would have been pulling metallics out of your fluid this entire time.
If you have that much particulate matter in your ATF then you should be able to find quite a bit when you remove it.
Especially if your AT is generating that much particulate. How many miles on this fluid?
I think your imagination is getting the best of you.
Have you ever flushed a transmission? While it might take 15-20 minutes to do, to get all the old fluid out takes no time when starting the car and turning it off. It cycles the majority of the fluid in maybe a minute of run time. I agree it might take quite a few passes to filter the fluid well, but the flow rate is quite fast.
