i put my trans together 3 or 4 times now and it won't shift, i could get it into neutral but thats it. i think i'm doing it right but somethings wrong.would anyone have a print of the 4 speed, if i can see it maybe i can coorrect the problem, the bottom end is from a 1966 bonnieville [ i belive]. its in a 73 bike so my parts book shows a 5 speed. anyone have an idea as to whats wrong.
