85 SE 2.8, Auto trans, 126XXX miles:
Do all th125 trans have a donut shaped magnet in the pan? When I first took the pan down I didn't know what it was. Looked like a large black blob til I stuck my finger in it and found it had a hole in the center. I took it out and cleaned it up and put it back in. The material attached to it was soft and mushy, didn't see much metal on it. By the amont of material that was attached to it, it must have been doing some good. Hope I didn't screw something up.

All auto trannies have magnets to catch clutch shavings that occur as normal wear. Sounds like yours was doing it's job.

Yup, the magnets are there for a reason. When I opened my trans, it had a buncha gunk on it. Of course when I put it all back together I missed putting it back in because it had magnetized itself to the underside of a can of wd-40 or something so i didnt find it till days later! I threw some strong magnets onto the bottom of the pan and its been fine since.

Thanks. That's what I was wanting to hear. The last automatic I had apart was an old 4 speed hydramatic out of a 56 Rambler, so I wasn't sure.

As mechanical parts wear in an engine or transmission, small metal particles or shavings are bound to result. Not only is the donut magnet in the transmission pan beneficial the magnetic oil drain plug on the engine also helps trap these potentially harmful particles. Certainly the filters take care of most of the crud but not all of the microscopic particles are filtered. The magnet is your second line of defense so make sure that they are in place. .
