I'm taking my 904 apart and it was rebuilt and never ran when I bought it. The guy didn't know what was done to it, but he said it was around $1000 bill.

My question is how can you tell what are deemed race clutches and bands vs stock? The clutches I took out look the same as the race kit from CRT, only difference is there were 4 in the front drum and now there is 5. Any help is appreciated. I've done 4 speeds all my life and rebuilt only stock autos and that was years ago.

Thanks in advance for your help
