Remote Transmission Filter

Okay, in my quest for power and reliability I am at the point of clearing my auto transmission. I plan on dropping the pan and removing any build debris and replacing whatever trans oil at that time.

However, I am also interested in putting an inline remote transmission filter on so that all of the small particles and clutch material are regularly caught and cleaned.

For example the standard pan filter is good to somewhere around 100 - 120 micron objects. The engine oil filter is 20 - 40 microns and there are a LOT of aftermarket options that use inexpensive engine oil filters.

I am considering this option (remote transmission kit). It uses a PH253 oil filter which is about $5 at auto zone. It's cheap enough you could change it every other 2 or 3 oil changes.

I got this idea from an article I read about how to help your car or truck go at least 300,000 miles. They mentioned that the auto trans fluid should have a better filter than what the factory offers.

Has anyone done this? What worked for you? I have a message into this company to see if their unit has a bypass valve so that if the filter gets plugged the oil can still go through the cooler and back to the tranny.

This seems like a good idea, although adding a remote filter for the transmission may add new places that could cause trouble, like an unexpected leak. And it might void the transmissions warranty, if there is one remaining.
Still, I think cooling the fluid and filtering it are both worthy goals that seem like good mods. Is there an obvious location for the filter and it's mounting hardware? Does the kit include hoses that are long enough to reach the best mounting location? Can you use any oil filter or is the kit limited to using only the filters supplied with the kit?
And your inquiry about by-pass valves is rather important.
Does an auto-tranny create lots of particulate and sludge, over the expected fluid change intervals? I was of the understanding that the biggest problem is that the tranny fluid will break down and basically become burnt from heat and extreme pressure.
Do the manufacturers not put better filters on trannies because of some of these issues, or are they just being cheap?
Are oil-filters really able to adequately filter transmission oil and the particulate that can accumulate from components wearing in an automatic transmission?

And on a similar but different vein, I am interested in doing a remote oil filter assembly for the 2.5L motor but so far, I have been unable to find a kit intended for the I4 motor. Lots of kits for the V6 and even the older I4 but not for my truck.

If anybody can point me at a kit the will work, that would be appreciated, much thanks.
