Its clutch dust- not "metal" but normal clutch wear particles. Metal particles in an automagic are not normal.
I'll be interested in seeing what ultimately failed in there, and I don't know just how abnormal that shaft movement is. The forward end of the input shaft is basically "carried" in the splines of the convertor turbine, so some movement is OK. I don't ever remember seeing *that* much in the Torqueflite 727s I've rebuilt, though. Of course the shafts on 727s are about twice that diameter and 4x the mass- that looks like a scale model of a transmission! With as small and light as FWD transmissions are, its amazing to me that they don't blow up every 20k miles.
pssh its still a heavy back breaker! took two to get it on the table. Good news is the more I take apart the lighter it gets... lol. And yeah compared to a 727 this is tiny.
as far as up and down play as shown in the video I'm not sure what is considered normal. service manual gives no specs. But I suspect what I have is not normal as the clank heard in the video is the sound of the inner shaft hitting the outer shaft.
It does give specs for in/out movement which is .005 - .025 in. This trans had .030 in.
Try hauling up an A340E. That's a real back breaker.
