I know what you mean, I rebuilt my fist 904 last year. Always thought I would hate transmission and never had any experience with them. Took it apart and thought I hope I know where everything goes. There was a long video series on youtube showing the assembly and reassembly. Really helped. After the rebuild wanted to do another! Transmissions are not bad and fun, just need to make sure stuff is in clearance. Yes I have a press and know what your talking about, I also bought the tool that compresses that piston to get the snap ring out. My dad is a machinist and has an endless supply of scrap steel shaft so he can make whatever bearing, bushing installer Ill need.
Must of worked right because my whiplash 318/904 setup is running great for the past year and I like to beat it up time to time.
