Hello, I purchased a 2001 Honda Civic EX today to use as a cheap daily commuter. Unfortunately, it makes an atrocious sound as demonstrated here:

In 1st gear, if you're under ~2500 RPMs, everything is fine but once you go over, there is a very loud rattling sound that is RPM dependent.

From then on, it occurs in every gear, even if you stay under 2500 RPMs. It isn't as audible in 5th but it's hard to tell since there's road noise at that point.

After you come to a stop, put the car into neutral, and then into first gear, the noise will stop until you get to ~2500 RPMs. Rinse and repeat.

I should also mention that I can hear faint rattling at idle that goes away when I push in the clutch, which makes me suspicious of the ISB.

The transmission does not grind between shifts and the clutch does not slip.

Do you guys think that it's the ISB or am I looking at a new transmission?

Thanks in advance!

Sounds like it....but to replace an ISB you have to remove and split open the trans, so at that point in time the other bearings should be checked and taken care of if needed.

FYI this was my ISB growling before being replaced

Will be sure to check the bearings as well. I've only done oil changes/brake pad changes so removing the tranny and figuring out what is bad will be a fun/interesting learning experience for me.

I really appreciate the video. I've watched all of the bad input shaft bearing videos on the first 5 pages of YT and yours shows the problem very clearly.

Based on my audio file, would you also agree that it is the input shaft bearing that is causing the noise?

Sounds similar to mine. It's really difficult to properly diagnose car issues with just an audio file.

As ezone has said to me many times: "don't hear anything over here".

Very true. Anywho, I've started the disassembly. Taking my sweet time so it's taking a while but I'm learning lots!
