The polarity of the magnets, as they relate to each other, maybe don't matter?

I'm probably overthinking this. But if you place two magnets on the trans pan, should they be placed with the same magnetic poles down? or should they be opposites?
I would think that two magnets placed apart would interact together and make one bigger magnetic field between them. Maybe this "bigger" magnetic field is to weak to matter for this application. But if they are working together it seems like the field would be stronger, and if they're fighting each other the fields would be weaker.

What do my Lesabre friends think?
 
What those magnets do is capture any ferrous material floating around in the fluid that come close enough to be attracted.

It will not matter one iota which direction they are place, unless you stack them on top of each other, in which case they will tell you which way they are going to line up by flipping over if the two poles match.

Just stick 'em on the pan. There is no quantum tunneling or rocket science involved here.

You DO NOT put two magnets on the pan, if you actually viewed the TSB youd know that one replaces the rectangle magnet, and ONE GOES ON THE FILTER

😳🤦‍♂️ Doh!!. I'm going to pretend that this was a trick question. Because sadly, I did actually look at this service bulletin.

The TSB is actually 5 pages and on p3 shows a sketch of the pan and where to locate them INSIDE the pan. BuickGirlFromMars has nailed it. Additionally, I've suffered thru and ponied up for a rebuild on my 4t65e, and the 2nd gen. family owned non-franchise shop that did my rebuild told me to do 30K fluid changes. For what I paid that man, I'm following his advice regardless of anyone else's opinion. To accommodate future fluid changes, I've installed an aftermarket drain pan Dorman 265-814, which has a drain plug; and the OEM gasket is rubber coated steel shim, way better than the floppy rubber POS that come with "filter kits." Just wipe it clean and reuse it. The 10mm pan bolts torque to 120 INCH POUNDS.

The oem filter is NOT a steel shim. It’s a plastic carrier with o rings (2 rows). Elastomeric technically for the plastic
