Buy a newer pan, a valve body filter bolt, drill and tap one hole. Convert to the newer filter and fluid tube.

GM did.

I use double O-rings on the pump end of the fluid tube.

That's not my definition of "stiction". That's what I call "debris". A small amount is not alarming. A small amount is totally normal.

HELL, NO. I've heard that story before. I don't know who invented it, but they should be beaten briskly about the head and shoulders.

Any grit in the fluid will destroy the soft-metal bushings, the roller thrust bearings, and the soft plastic thrust washers. Grit would score shafts and harm the geartrain. it would wear the pump, and the valves in the valve body, especially those transmissions that have an aluminum valve body. It does NOTHING beneficial. If you're lucky, it settles-out in the pan overnight never to be picked-up again.

Maybe. I suspect they'll claim anything if it helps sell the product.

Doesn't matter. Convert to the newer filter.
