Honestly I've always hated the manual trans in this car. During high rpm shifting I get locked out of gear so often you wouldn't believe it. I've tried everything and nothing fixes it, even let other people drive it and they all have the same issue. What sucks even more is when you do make the shift it'll randomly just cut power (even though mine doesn't do that anymore) or it'll do that wonderful thing it likes to do where 4th falls apart and the whole transmission just goes to shit.
My friend let be borrow his 5spd Evo X and it was like a dream. Never missed a shift, felt solid as hell. Not a single complaint about that trans, made me hate my car/
