Have any of you ever worked on a 42RH which is a 904 with an OD? and seen the differences in the cases between a 904 and 42RH...and the internals?.....How the rear drum is snapped ringed in on a 42rh..where the 904 is not...and how the od piston mounts on the back of the case where as the 904 does not have one....GOOOD LUCK>>>>
buy a gear vendor overdrive for a 904........
