Pan filters are a joke. Many transmissions have nothing but screens(and some have tiny screens within the VB or transmission that can clog).
Magnets only filter magnetic particles.
I've decided to go this route. I'm up in the air on the bypass vs inline filters. I don't want to take my TL far from stock looking in case I decide to sell it so I'm leaning toward inline.
What I can't find info on is are the Magnafine filters just a bunch of magnets that the fluid passes over or is it an actual filter plus magnets? Also having trouble finding one that's only for 3/8" line and not for 5/16 AND 3/8" line.
Anyway to improve filtration will allow the fluid to last longer. This is a benefit for those that use boutique long lasting fluids.
Anyway to remove wear particles will improve the life of all components that need fluid for lubrication. Wornout valvebodies and seals seems to be more common then ever.
I've also seen transmission shift better with filtered ATF. This to me shows that factory filtration is a joke, and that suspended particles can affect clutch/band lockup.
Points of failures are already built into the transmission. IMO, adding an inline full flow or bypass filter eliminates more points of failures then it creates.
All the inline filters, like the Magnefine, have bypasses. Read their literature. I've seen them cut apart even if noone has posted pictures. They're small pleated filters and some have a additonal magnets. Wix, Transdapt.... make these inline filters. And, certain automakers require ones to be added after a warranty rebuild. What does that say about inline filtration and OE filtration?
All 'ph8a' filters used by the 'other brands' rely on the bypass built into the oil filter. These filters are also pretty cheap enough to replace regularly eliminating and clogged filter issues.
Why not question the factory filtration? micron rating of factory filtration? effectiveness of factory filtration? OE filtration is where there is nothing to talk about!!!!
