yea, it could be just the blocker rings, but if it has alot of abusive miles on it usually the sliders and gears are f'd up too. other thing is once you open it up I can bet that you'll find other things wrong, and it doesn't make sense to just fix the syncro if it needs a cluster gear kit or input shaft ect. I guess I'm just tryin to say it could get expensive. what year is the tranny? has it been rebuit before?
