alright thanks a lot for all the help guys, got some magnets on the way.

Yeah, I would say the outside because on the inside, it'll basically be useless. neodymium magnets reach their curie point at 176*F and a transmission gets much hotter than that, but if on the outside, they'll remain cooler and should maintain their magnetism.

Edit: HD magnets are neodymuium magnets. FYI

But, if you want a magnet that is much more heat resistant, I would recommend using a samarium-cobalt magnet instead. They're much cheaper, they ARE weaker, but will definitely keep their magnetism in a very high temp environment such as being submerged in very hot transmission fluid.

Thank you very much for that information on the hard drive magnets.

I read on some forum that HD’* made after 95 did not have magnets. Wrong.

Just took apart a 2000 Fujitsu and it has two strong little curved magnets where you said.

And of course I threw away 3 old HD’* last month. Arg.

Now to find out how to remove the magnets from the steel plates they are attached to.
PS:I apologize to Redwingsfan34 for barging in on your post.

Thanks again.

then again can to strong of a magnet affect your solenoid'* , electronics???

No, I wondered that myself.. after Pete got the magnets...and nearly every person that bought some got injured.. it was apparent that the cars would be ok. Members had issues...but the shifting was good.

The effective flux field of even that strong of a magnet cannot be felt even as far away as the pan gasket.

I've been running with old hard drive magnets on the Zilla'* trans. They bought me time on a broken trans until I could get it to the shop. They were VERY effective and collected far more than the stock pan magnet would have.

Since it'll probably help everyone reading this...

I usually use an old, pointed blade, pocket knife to pry the magents off their base. CAREFULLY find the right angle to wedge the knife blade under there, sharp edge towards the middle of the magnet, and push/wiggle til it pops loose.

DO NOT POINT THE KNIFE TOWARDS YOURSELF OR YOUR HAND. The magnet will eventually pop loose, sometimes allowing the knife to jump in the direction you are pushing. You don't want to be where it'* heading.

You may need to clean off some flaking coating from the magenet now. But once that'* done you'll have a very strong magent, and hopefully as much blood as you started with.
