Had the same problem for a while and finally while on a fun run a hour away from home my tranny broke and was stuck in 4th gear. Made it home after driving a hour in 4th gear at 60 mph. Opened up my tranny and found my Shift fork broke! Synchros looked fine. Changed the shift selector only and voila!! Can down shift into 3rd again w/ no grinding or kicking out at all.
It could either be the synchros, retaining clip or shift fork.
