Thank you for your interesting post and photos. In my own case, I have no idea how much, if any maintainence my Allison received prior to when I bought it at approx. 70,000 mi.
First thing I did was change all the fluids - was pleased to find the auto trans. fluid still "red"; no sign of heat discoloration.
My magnetic plug had NO metal filings - soin your case, I would be concerned - obviously they are ferrus ( or the magnet wouldn't have picked them up ) I defer to the transmission experts in here - my personal opinion is that looks like maybe the clutch plates are incurring excessive wear.
2013 3500 long bed crew cab. Purchased at approx. 80,000; now have 91,000, convert to CP3. DPF "triggerd" a limp mode, so was cut out of the vehicle & cleaned by a DPF cleaning co., on re-installation, everything back to normal. Would never ever think of something as nasty and as anti bunny wabbet as a full-delete...after all..dosnt everyone like the fun & excitement of being stuck by the side of a Interstate in the ran while towing when one's truck's computer decides to go into "limp mode"...?.
