I haven't seen the normal manual, but like you say I have heard it isn't in that one. So I'm hoping someone has an alternativeI think the car's manual just details the procedure to remove the gearbox, not how to strip it down and rebuild. I did have a look myself as I was interested in finding out how it went together and how easy/hard it is to rebuild should I ever need to. I presume there is a separate workshop manual but I've never seen one on the usual sites with car manuals.
