Once in a while i would hear a grinding noise in my tranny while it is warm. It doesnt happen all the time though just once in a while after my altenator has been fuccin with me. Its a kind of grinding metallic noise like when u release your clutch too slow or something, but it goes away when i hold in the clutch and comes back when i let go. what could it be? thanks in advance to anyon who replies
It could be a couple of things, either you have a bad disk, pressure plate, or a bad throwout bearing. Any of which will mean you will need to pull the tranny to examine it. You can replace any of these parts but I would recommend that you go with a full replacement. Worst case scenerio is that you have a bad tranny, hopefully it is not that. If you are good with cars pull it apart and look at the clutch components.
That problem has nothing to do with your clutch, pressure plate or clutch disk so disregard the last reply.
That grinding noise that you hear is your input shaft bearing. That means that you will have to pull the tranny off, open it up, and put in a new bearing.
It isnt the easiest job in the world, but if you know your way around your engine then you should be able to pull it off with the help of a helms manual.
While your inside there you might as well replace the other ball bearings and the oil seals if you have the money to do it.
If your not comfortable doing this work on your own then you might want to get some quotes from shops or find someone local that works out of their garage to help you out.
If you dont replace it, it will eventually blow that bearing out and that is bad news. If a piece of metal gets between some of the gears then you can kiss that tranny goodbye.

B R… can you make a simple write up for me or would i be better off looking at he helm’s, and plus do you know how much a new bearing would cost

I suggest that you study up in the helms manual first, then ask questions after you read up on it. That way you will have a basic idea of what you are doing and can ask more detailed questions pertaining to what you need info on.
The bearing itself will cost you around $60 + tax from the dealer.
You will also need some MTF (manual transmission fluid) and I recommend that you buy the Honda MTF from the dealer. I wouldnt run anything else in my tranny.
I also wouldnt recommend that you do this if your not very mechanically inclined or if you havent done any work in an engine before. It is very discouraging when you tear apart the tranny and realize that you have to take it all apart to get to the bearing.
You will see what I am talking about when you look in the helms manual.

Alright, ill DL the helm’s and then read it… thanks for all your help

Yeah that’s the problem. On my 1990 Civic Si the input shaft bearing went; made a very annoying sound all the time which only got worse. I didn’t want to spend the money to get a shop to do a rebuild so I did a DOHC VTEC swap 
It should prolly be fine for a while though while you decide what you’re going to do.
