I'm tearing down an NP205 to rebuild but having trouble removing the front output shaft assembly. The unit repair manual (GM's rebuild manual) just says to remove the rear cover bolts and use a soft hammer to drive it out. I'm using a deadblow hammer with nothing moving. Looks like the shift fork might be holding it in, but the repair manual has that being removed after the front output. Anyone been thru this before that could give me some tips? I can get pics of it later today if needed.
