Hey all,

I'm trying to figure out how to ID an auto tranny from 80's era CJ's. I
know Jeep used the Chrysler 904 and 999 tranny's in this time frame, but I
don't know how to tell the two apart. AFAIK, those two trannys used the
exact same case, but the internals are a bit different. Anybody know?

Thanks,

Tim in

Start with this, there were only a few options on 80's CJ's
