My 03 celica has never had any issues since ive had it. However recently my 3rd gear has begun to grind when shifting into it, nearly 50% of the time. It sounds terrible. And feels terrible when it happens. Nothing pisses me off more than that I can honestly say. Im guessing its a synchro going bad. Other gears are fine. If its expensive to fix I'm not sure what I'll do. The car itself is worth only 5 grand or so.
