Default Magnetic transmission oil drain plug?

does anyone sell one?

believe I've had them in the past but Brattons catalog does not list one.

drained the trans oil today and there were a few little filings in the plug......

A small magnet and a bit of epoxy is all you need to turn your plug into a magnetic one!

I made my own for engine trans and rear end using 1/4” long 1/4” diameter high strength magnets I bought online. Just drill into drain plugs 3/16” deep 1/4” wide and stick them in they will hold themselves no glue needed very difficult to get out. When I change the oils the plugs are always loaded with “fuzz” that would have been circulating otherwise. I believe them to be very effective at keeping the oil’s free of fillings. Cylinders wear and everyone grinds a gear now and then.

If it's a pipe thread McMaster-Carr has them. Don't be alarmed the first time you see how many crumbs are stuck to it.

I believe that babbitt is non-magnetic. However, cotter pins fatigue and wind up in the pan. What else is magnetic that would stick to a magnetic drain plug?

As pistons go up and down the rings take off microscopic scrapings "the black fuzz" of the cylinder walls, esp prevalent after honing the cylinders.

I think he is asking about the transmission drain plug.

I agree, McMaster-Carr has magnetic plugs. I also use one in my Mitchell O/D and rear end.

There are no bolts to pull it off. Handy for those that crunch gears a lot.

Just a point of interest...
I have magnetic plugs in all three locations:
engine, tranny and rear end.
When I pull the plugs to check/drain oil, I always get
some 'dust' on the plugs. Not very much, but a little.
I highly recommend them.
I think I got them at McMaster-Carr.

I've been using a magnet on every drain plug (4 per car including O/D) for years. I just put the magnet on the plug and screw it in. It never moves and It's easy to clean when I pull it off the plug. They cost a matter of cents each.
