Transmission Pan Magnets?

[Turbo67camaro]

I see transmission pan magnets for sale, to attract and hold metal particles.

On the surface, it sounds like using them is a good idea.

However, is it possible for the magnetic fields they emit, to interfere with the electronics or mechanical functions of a late model transmission like a 4L60E or 4L80E?

If they are OK to use, do they have to be epoxied or otherwise attached to the pan, or will a powerful enough magnet (say a rare earth magnet) simply stay put, when used with a steel pan?

Rare earth magnets are powerful enough, where I imagine they could be placed on the outside of the pan, and still possibly be effective.

No problems if you want to put a magnet in the pan. The factory puts a magnet in the pan. It will hold it's self in place.
