both the TCS and the A+A have their pros and cons , I've had both ,Ii like the TCS because you can fit 5 thick clutches in it because the snap ring groove is higher BUT they put the vent valve in the WRONG place and kolene steels won't fit because the grooves for the steels are a little narrow , I have an EARLY TCS drum.
my TCS drum is just over a year old & my trans man managed to fit 6 kolenes into this drum. do you think they may have upgraded from your earlier version?

I talked to someone in the know and he had addressed the issues that my drum has with them and it seemed to be hit and miss as to whether it came in correct or not still. In their defense the drum I have is probably 6 or 7 years old , it was one of their first and I got it for half of what they sell for now. I'll move the vent and you can grind the edges of the kolene steels to make them fit properly. But if I were starting from scratch I'd pony up for the A+A .

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.

 The A&A aluminum drum in my car has hundreds of passes on it and looks like it's hardly been used when I take it apart to check things over in the off season. I change the trans fluid every 40 runs with Dextron 3 and don't ever have the sludge shown in the picture above. I run a smooth red band from A&A as well and run a Tranzact valve body with a clean 2-3 shift which may help prevent premature drum wear.

and what do you think the silver material on those fingers is? swiss cheese? it wear from the aluminum drum - plain and simple... i'm not bashing the aluminum drum... if you read my post it states that for a a car that drives on the street you will have to deal with this - that is a fact and that will not change. this was not form an old tranny - it was a seasonal rebuild and the drum had wear at the band location. here is that drum before it was cut.

I can't make out any aluminum in you first picture. You said 50 runs on it. That's a lot of crap in there for 50 runs. I wouldn't put aluminum drum in a car that saw street duty either. It looks like BAD Swiss cheese.  edit: I'd expect the wear pictured on the drum after 600 passes.

If you buy anyone's Aluminium Drum, make sure you run a Red lined band. The Kevlar bands are too aggressive and will wear the drum out quickly.
AL....
thats what i use.Red band
I got my drum from JPT, he makes them in house,on his own CNC equipment. i think he said he was the first one to do that.
Have had mine over 5 years and still looks great..

the picture of the drum was in fact 6-800 passes...

Does anybody make the billet steel drum for a 904?
TCS
I personally wouldn't bother unless, I was 100% sure I needed the
extra clamping of the bigger piston.
I'm using an OEM front drum on my first 904, due to lack of funds.
The next one will be aluminum. 904 drums don't have the front
drum explosions the 727s do, as their mass and diameter are
much less.
727 high gear drum is 3480.5 grams and 7.496" in diameter
904 high gear drum is 2378 grams and 5.876" in diameter
This example shows the 904 drum is 2.43 lbs. lighter and 1.620" less in diameter.
