Filter

If you are replacing the filter, do the cleaning and fluid flush first. This will allow the old filter to trap contaminants that may be circulating in the old fluid or loosened by the cleaning chemical.
Many flush equipment manufacturers also recommend adding “conditioner” to the AFT when the fluid is replaced. Such products are claimed to revitalize seals and o-rings, help prevent leaks, extend the life of the fluid and help smooth shifts. A conditioner may not be absolutely necessary. But if it reduces comebacks, use it.

As for the transmission filter, a change usually isn’t needed until 60,000 to 100,000 miles if the fluid has been flushed every 30,000 miles. Many Asian transmissions don’t even have a filter. They just use a screen to keep debris from being sucked into the transmission. Even regular ATF filters are relatively coarse compared to an engine oil filter. A typical ATF filter may have a rating of 60 to 125 microns or higher — compared to 20 to 25 microns for an oil filter. The reason why is so the filter will pass enough fluid when the ATF is cold. Yet it only takes a particle the size of a human hair (about 30 microns) to jam a transmission valve!
