Buy a metallic cooler line filter housing - trans fluid ignites pretty easy if the plastic filter body melts or fractures. Magnefine Boss had the best filter out there - used a magnet on the inlet side plus a good filter media with bypass inside. Screwed together so you could take the filter out for examination.

We tested it and it took over 4 grams of clutch debris to block the filter media. That means you aren't likely to go far when you fail that much friction material. And with the magnet it continues to collect any ferrous material. The aluminum gets trapped in the filter media.

The FWD cars used 5/16" line, most RWD cars in the day used 3/8" and so did most gas engine trucks, and we went to 1/2" lines on the 47/48 diesel for extra cooling of the lube.
