if they are brass particles, it'd be a thrust washer thats badly
worn.  if its aluminum: with old 727s, quite often, the thrust 
washer on the rear drum wears and the rear drum starts eating 
away at the main case where the drum/case clearance is tight..  
If this is what you've got going on, the case, though chewed a 
bit, is save-able.    (I know this happens on 66->later 727s, 
I've never taken a 62-65 727 apart, but AFIAK, they are the same
in this regard).

take it to someone who knows 727s and is known not to be a crook,
check with a local mopar club if you can't find one word of mouth.
if it "pulls in every gear" and otherwise works okay,  replacing 
all the seals, frictions, and fibre and brass thrush washers will,
most likely, fix you up.

since you can't buy a new 727 anymore, you'd be buying a rebuilt one,
which may or may not have had the old thrust washers replaced (it
may have just had the seals replaced)  Plus, a 62 727 is somewhat
unique in that it is a cable shift tranny with a fine-spline input
shaft (special torque converter required, at least, special to the
62-65s), and ball-n-trunion output shaft.  finding a "new" or at 
least, trusted 62-64 727 might be a lot tougher than finding someone
who can rebuild your old one...
