After you remove all 3 of the electrical switches from the side then remove the speedo pinion, remove the stopper pin bolt (holds the shifter slider in), remove return spring plug, spring and plunger (right side just forward of the stopper pin bolt). Remove reverse-check-sleeve assy. Remove front cover (SAVE ALL SHIMS). Remove front snap-ring.
NOW unbolt back housing and pull rear housing off (using a big-a$$ gear puller)
... and call me in the morning!
