I'm trying to put a new clutch into my 03 wrx, and I can't get the transmission to separate from the engine. After using a prybar, I've got about half an inch of separation at the top, and maybe half that at the bottom, but it just won't move any further. Basically, does anyone have any suggestions for getting the rest of the way off, or is there something special that needs to be done? 3 of us were shoving on it and couldn't get it to move any further.
