Not withstanding the childish posts on here, the 904 has its place, but a dependable strong transmission it definitely is NOT. I rebuilt my first 904 in 1980. It was simple; just as simple as a 727. All this hype about how great a 904 is is just rubbish. Anything can be built up if you're working with cubic dollars. A 904 belongs behind a mild small block. If I really wanted to slam a 904 I'd talk about their junk converters that crack because the metal thins out just inside the pump slots. Arguing against a 727 for the street is just sad.
