92K on 17 wrx 6 speed. New clutch and TOB at 30K. No issues, until last week. I believe I lost 6th gear syncro but i'm no transmission guy. I assume its a major teardown so I will be pinching some pennies, and driving a 5 speed for a few weeks. Still can engage into 6th gear, but with any power the stick is knocked out of spot.
Best car I've ever owned though!
Edit* car is all stock. even the tune...
