how to drain a 904

well im just keeping bcoz its numbers matching to the car but have no intention of ever using it again which don't make sense ....I should just toss it ....but being a relentless pack rat.

I know what you mean. I've got an old 904 that came behind a 273 Commando Barracuda I had. I believe it's got some different internals, like maybe valve body or governor springs so it will upshift at a higher RPM, or so I've been told.

Don't think I'll ever use it since I'm a 4-speed guy, but how could ever get rid of it?? Plus it's only got about 68K orig miles on it.
