This particular LF3487 was put into transmission service in a '97 Corolla with a Aisin 3spd automatic running Dexron VI. These 3 speeds do not share fluid with the differential. 189,007 total miles.
This was a test of the setup, to see how far I could take this filter and how the trans would behave with it during the cold months. The amount of high mileage units around is a testament to these trannys not really seeming to care how much metal floats around in the fluid. The remote mount is downstream of the radiator, the filter is in a vertical position (threads facing up). It's tucked into the wheel well where the air silencer once resided. The test was cut short, was hoping for 30K, as the bottom of the filter corroded through causing a pinhole leak. Need to move out of the rust belt...
There was a considerable amount of corrosion on the lip, however, the seam still appeared to be intact.
The bottom sides of the can had corrosion at some sort of seam, one area looked pretty bad.
The source of my leak was the bottom of the can, a pinhole from two years of corrosion. Glad to see that it wasn't my plumbing for the remote mount.
Appears to be a nitrile ADBV, felt soft and pliable.
The microglass media had a solid feel, the metal tube and endcaps makes it feel very rigid. The media had a slight fabric type appearance, guessing that it likely can hold a large amount of particulate.
These trannys come with a rockcatcher screen so I wasn't to surprised to find a large amount of glitter and clutch material in the fluid that drained off the media.
As mentioned earlier, the mount is positioned in the front wheel well behind the splashgaurds that overlap with the body panels. I don't believe that it's mist as the rest of the metal in that area, including the mount and its hardware, looks better than the rest of the vehicle. Perhaps condensation due to location?
Nice large filter with microglass media. Wish I could have run this out to my planned 30K, in this application it could likely go out further than that. A rust proofing compound is definitely in order for extended runs in rustbelt country. The replacement was coated in Krown T40.
