First thing you have to do on a 904 transmission is eliminate the reverse wound spring in the front clutch. Sometimes they have a tendency to unwrap an that makes for a real mess. So the first part I bought was the spring kit from cope that was designed by A&A.
904 Aluminum Multi-Spring Retainer Kit - A&A Transmissions
Like said above times change you can now get the properly wound spring from ATI I believe it is for about 35 bucks.
Then went with the thicker struts or links for the band went with a aluminum Billet Servo all that good stuff. I believe it was Red Eagle clutches and kohlene steels and a reverse pattern Griner low band apply valve body.
Basically I copied an A&A or a CRT 904 transmission build. With help over the phone from John. A&A just want to sale me parts or transmissions, no technical support. They treated me the same way at Mopar Nationals when I was trying to buy parts from them. So I just put the parts back down and said no thanks and left.
