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,
