Is there any reason to use (or not to use) Torque Drive in the Allison 5spd of my '02 Duramax?

Mookie- the original spin on comes with a magnet laying around the hole where the filter stud goes into the filter--when changing you are to clean it off and transfer it to the new filter every time---looks like someone has prob thrown yours out somewhere along the line--

Just an FYI, pulled this off of Allison's website:

Q. Automatic Transmission Fluid (ATF) - Can I use synthetic fluid?
A. Any fluid that meets DEXRON III requirements is suitable for use in the Allison 1000 Series™. Always verify that the container reads DEXRON III, regardless of whether it is mineral-based or synthetic.

Q. Automatic Transmission Fluid (ATF) - Can I use TranSynd fluid?
A. TranSynd is a fully synthetic transmission fluid available from Allison Distributors/Dealers or at GM dealers. TranSynd is a licensed DEXRON III product and has been extensively tested by Allison Engineering in a broad range of Allison products. While TranSynd was developed mainly to meet the harsh operating conditions of heavy-duty transmissions in severe operating conditions like transit buses, its benefits translate to the pickup truck market.
