Which bearing is making noise from my transmission?

With the mileage on your car it could be an input shaft bearing. However, if it shifts good and seems to behave otherwise, Hondas are prety tough and the bearings last for a long time.

The throwout bearing is definately bda as when you put pressure on it, the moise goes away. If it were the input shaft, the noise might even get louder as doing this allows the input shaft more freedom to move around becasue the clutch plate is free to move and it is attached to the end of the input shaft. Also, your pilot bearing is in need of replacement as well.
Depending on what you plan to do with the car, you can fix this in 2 ways. You can get a kit with a friction plate, pressure plate, thrwout bearing and pilot bearing. The other option is to just get a friction plate and you usually have to get the pilot and throwout seperately in that case. Some companies will include them but not many. The problem with the friction plate only is that the pressure plate cannot be re-surfaced and the friction plate might not engage smoothly after break in.
You will also have to re-surface the flywheel if you want to do it the right way with the full clutch kit.
Getting just the friction plate and bearings is just a patch and can cause vibration and other issues, but it will work for a while. If you plan to drive it till it dies and not keeping it for long, jsut patch it.

Hi Jeff,

Seems smething is loose or has dropped into the bell housing and might require the trans to be removed to verify.

Remove the splash shield under trans and engine to check if you can see anything.

Intermittent noise is not likely to be due to trans internal components failing.

From the symptom description, it should be external. Does depressing the clutch slightly cause the noise pevel or pitch to change?

So we can conclude that the noise is present when the main shaft is turning.

Worn trans internal bearings would produce whining noises instead of what you have described. The only possibllity of the described noise is a bad bearing, one of the balls is cracked or rough thus causing the noise.

Looks like you would have to at least drop the trans to check out.

The problem of the clutch sticking after going through floods should not be the cause of the problem. However water getting into the trans or any external bearings would.

You are welcomed and too bad this is something that cannot be avoided.

Thank you for using 2carpros.

I've seen this noise be both the transmission input shaft bearing (inside the transmission) as well as the clutch release bearing (a clutch bearing).

My recommendation: Pull the transmission and check the release bearing first, if it is not the culprit, it's the input shaft bearing located inside the transmission.

Hi nick1980,

Did you check the trans fluid level and condition?
