this is about 50 runs on an aluminum drum


use a billet steel one from CRT , of you plan on driving it on the street... - John is a great guy to deal with.



I think this picture and testimony is an example of not knowing
what you're looking at. OEM transmissions produce the same residue,
in complete passenger car applications.

I have/had an A&A aluminum drum in my 727 with way more than 50
passes on it and it has never looked like that.

Both drums have their place but, both solve the safety issues of
the OEM forged powder drum.

I hate for one guy's opinion to mislead potential customers for
the aluminum drum. It's not usually necessary but, is not the
cause for the grey sludge pictured.
