I spoke with my contact at Derale and on the Replacement Filter # D13092 it has a micron rating of 21. He stated that you do not want to go more fine than that because it can strip out the abrasives in the transmission fluid that are needed for proper operation of the transmission.
What is everyone's thoughts on that reply from the Derale tech?
Yikes! If that were true, the gears, bearings, clutches, etc. would be worn out long before the warranty
was up. There are friction modifiers in ATF but not abrasives, as far as I know. The 'tech' you spoke to
must have been the floor sweeper that was covering the phones while everyone was at lunch...
