If you want your good gearing back, consider replacing the input shaft bearing yourself. It's actually a straightforward task. Google "honda civic input shaft bearing replacement" and you should see a couple different DIY guides that people have created with pictures and everything. The part is pretty cheap, and with some basic tools and a few hours you could have it working properly again. I'm considering doing this but my car is a daily driver and I don't want to risk not getting it put back together in one weekend and being without a car.

If I knew what I knew now I'd be on the lookout for a good used transmission and swap it when the time was right. My transmission has always been loud, it just got a LOT louder in the last week and made be start worrying about it. Now its at the point where I dont want to drive it and risk massive failure. I have seen a lot of suggestions for swapping the input bearing but it looks like its more complicated than people say and there is no guarantee that I won't have a bad shaft or something else and I will still have to get a new trans. My car just hit 192,000 and I've had it since 149k. Hope yours hangs in there but at least you know that you could do what I did if you find yourself in a pinch.
