you can pull the side cover off without removing the trans--drain the oil-put in neutral, remove shift arms-remove bolts in side cover-remove the cover-get your head up next to it or use a mirror and check the synchro- use a screw driver to pry it off the gear hub, squirt some oil or lube on it and re-install. I was able to do this on a 40 sedan and it had less room than a 1/2 ton pick up. synchro should have some gap between it and the gear so it will work properly if it goes flush with the gear it is worn out or mis-manufatured
