C & P GM Transmission Filter

[Snagglefoot]

Here is a cut up GM transmission filter from my 6L90 that was run from 150,000 miles to 200,000 miles. The housing is hard brittle plastic so I used a set of garden shears to smash the edges of it to open it up. I found two sheets of filter material measuring about 0.07 inches thick. The inside of the housing had vanes to direct the flow from between the two sheets. The in-flow was between the sheets. What I found was fine metallic particles. This is a real filter and not what some folks call a “ Rock Catcher”. Enjoy.

Here is the thickness of one sheet of filter material. Also the insides of both side of the filter had vanes to direct flow.

That looks like Filtran material that I've seen in some other transmission filters

Good C&P

what did the pan and magnet look like?

I posted this earlier this summer in the transmission fluid change section. The bottom of the pan was clean. The magnet did its job and the fluid was clean. I had been pulling 3 quarts out and replacing them with fresh Dex 6 once a year using a plastic tube and vac through the fill tube. The pan drop required 6 quarts.

Looks about what mine looked like last year when I did a pan drop/filter change on my '11 Silverado with 60k miles.
