all three of my vehicles have external spin on filters on the transmission cooling system. both of my accords are set up just like the two photos with the white filter, my truck is the black filter. between these three vehicles were well over 200k miles without an issue. FL1a or fram PH8a sized filters. use the correct teflon tape for the application and apply correctly and you shouldn’t have any extra failure points since both of these systems had flexible rubber hose from factory in the system. proper installation is required for anything you do to your power train.
No. More filters are more better.
Plus that foam or felt 100+ micron transmission pickup filter will screen out all the big junk that could take out the pump.

Some transmissions especially Japanese ones sometimes just have a metal mesh screen. My GX460 has what they call a felt strainer which appears to be the type of material you mentioned.
If you are worried about leak points that's fine, most of us are not. I've ran Magnefine filter on all my automatic vehicles and never had a leak.
Filter element + a magnet is good insurance for the valvebody.
Very few if any units produced in the last 25 years or so have a mesh screen.

And I'm guessing, most of you haven't been under a multitude of vehicles over the past 48 years, investigating transmission fluid leaks. If I'm wrong, I apologize.
Just added an 8A sized filter to the outlet of the cooler circuit. Replaced the factory rock catcher but I’m not pulling this pan again. The rear bolts are a nightmare.
I do need to rummage for some leftover rubber I used between the toolbox & bed of my GMC to put between the cooler line & the fitting that’s touching. Other than that, this one’s done.
I’ll have to definitely do this at some point
Those are some beautiful leak points you put on there!
Everything fails given a long enough timespan. Considering the reliability of the factory quickly connects, I have a feeling these hoses & fittings will be just fine. If they last 200k mi, & I still haven’t sold the truck, I’ll replace them.
Almost bullet proof using hydraulic hose.
Yes. And if you've broken a few trannie filters apart, you've seen there are plainly woven elements and others with a 'wave-to-the-weave' and accent lines.
Being a sheer fabric, I think BITOGers' wives would take to lingerie made of the stuff.
Imagine her surprise...
Sweet!
Leave the OEM filter in place - it’s made by Filtran/Toyo Roki/Mahle out of a polyester density “felt”. They don’t plug unless there’s a catastrophic transmission failure from internal parts failing(like the sun gear in a 4L60 shattering).
Even Allison transmissions used in buses and beer trucks/concrete mixers have a filter on the pickup and 1-2 externally serviceable filters.

This is really the point of when I did it and will do it again - BrendanC and myself both found some large OG Fram Ultra’s - and as in the past - will install that 20 micron good flowing gem while my pan filter is fresh - and then it can stay there for a long time. I can swap ATF from the new filter mount …
What I do on the metal lines - is crimp the seal with a connector (3.) - get rid of connector - and then just slide the hose over that and clamp - never had a leak doing that …

I run equipment with massive “snake dens” of hoses at 3000 psi and rarely have a leak - lots of the DIY adds (like hot rod builds) - have a first class supply of over built kit - way better than OEM that’s all about building a car at the pace of fast food lunch …
