Yeah I dont know if anyone has ever gauged the volume of contaminants removed from the system using a machine vs dropping everything. The one I saw had a sort of catch can that trapped stuff as it flowed thru the system. I believe they disconnected the lines from trans to radiator, pumped fluid thru one side and circulated out the other. That caught alot of junk. Then they connected the machine to the transmission side and ran it through, again picking up alot of what I assume was friction material from inside the T/C. They may have had the vehicle running and spinning the transmission as well, I dont recall as it was some time ago but the catch can had quite a bit of different colored gunk in it afterwords. Way more than I have ever gotten off the pan magnet.
It would be neat to see a blackstone labs study on the fluid before and after vs just dropping the T/C and draining it.
I assume it had some kind of mesh filter or centrifuge effect inside to pull the contaminants out of the fluid but I never got inside the machine to find out. I also dont recall ever seeing any kind of solvent being used, thought it was just the same trans fluid used to fill the transmission.
