I recently had these cables installed and since then my cars been making a pretty loud scratchy noise. My mechanic claims it’s the shifter cable bushings the cable comes with as it’s metal and causing the sound from the vibrations. I went to a second mechanic and he claims the same thing. When I reached out to Hybrid Racing they said it shouldn’t make this sound. I don’t hear anyone else having this issue. HR asked for a recording of the sound but it’s impossible to record it. Tried driving over an hour to get a recording of it.

The issue is when I rev it to about 3-4 rpm it makes the scratchy noise. Sounds similar the heat shield making a noise. If I put it in neutral while the car is moving it stops but soon as I put it back into gear it starts making the scratchy noise. Il

has anyone else experience this before. Im at a loss here and considering switching back to my oem shifter cable. The noise is just not worth the improvements.

Heat shield isn't loose?

I have the exact same problem after having a usually pretty reliable mechanic install the shifter cable linked here: Hybrid Racing 9th Gen Civic Performance Shifter Cables (12-15 Civic Si)
I have removed the entire center console trying to figure it out, but have had no luck so far. If you ever find a solution, please post an update.
The only bandaid that helps a bit so far was gluing some neoprene sheets everywhere that I could get it to fit to deaden the grinding/rattling sound a bit.
It barely makes any difference, but at least I feel like I have tried.

the noise was so unbearable for me I ended up paying to switch it back to the oem cable. Unfortunately I still have the scratchy sounds on 3rd and 4th gear but it’s much less pronounced. I’m thinking possibly my hybrid racing short shifter is also part of the culprit in causing the noise. Maybe tighter on the cable?. Did you by chance change your shifter recently as well?

My car is entirely stock, except for the shifter cable.

I bought it brand new, dealer serviced with OEM parts every 3,000 miles or six months, and I had under 35,000 miles on it,

And then over a three day period the car went from problem-free to...
1) difficult to shift. Then,..
2) the transmission started acting semi-independently of my clutch-pedal-shifting, so lagging or lurching when I clutch in or out. Then,...
3) all the odd-numbered gears just gave up, and I was only being able to use even-numbered gears (2nd, 4th and 6th were ok, but 1st, 3rd and 5th gear were impossible to shift into). Then,...
4) Stop at a red light, and have to push my car off the road when the light turned green, and then get towed.

Regular service dealer can't source OEM clutch cables, and nobody else seems to have any. So I went for the upgraded racing cables since it seemed like a safer bet than salvaging a used one from a junkyard, or trying to DIY a solution out of ROMEX, duct tape, and methamphetamine.

In retrospect, I should have gone for the drug-fueled creative option, but it is never too late to try...

Hence the attempts at sound deadening

This post is way to long, but I'm just going to post it anyway. Sorry

nope.. I’m on stock cable now. Either I got used to the noise or it’s a lot quieter now. Is yours making noise with the new cable?
Yeah it is, I’ve been told it was a clutch release bearing so I did a clutch job sound was still there replaced the whole transmission sound is still there

If you ever find out please post here. I’ve pretty much given up. I wish I didn’t modify anything. I changed the short shifter and shifter cable at the same time thinking it would be an awesome upgrade. I wish I changed only the short shifter first so I can tell where it went wrong.. the only thing that might resolve the noise for me is to change the short shifter back to stock which I won’t as im happy with it.

The noise started around 3k rpm and the higher the rpm goes, the louder the noise right?

I have just installed the HR cable, same problem.
The only thing I did not follow the service manual was the torque spec for the shifter bushings. I will do the correct torque, double check the rubber seal, and put some silicone grease on the cable end . If the noise goes away, I will let you guys know

What’s interesting is I reverted back to the stock cable And the issue is still there. Granted it wasn’t as loud. If anything it has subsided a lot to the point it almost sounds normal. Like if the hr cable noise was a 10… going back to stock cable was a 4-5, and then over time now it’s a 1-2.

Did you cut your grommet when you put the HR cable?

yes. My mechanic did the work actually. He’s very good at his job.. he explained to the bushing is too tight or something like that leaving no give. I even went as far as going to another mechanic for a second opinion who said the same thing so I gave up and had my mechanic revert to stock. Sad cause the shifter felt so nice but stock isn’t too bad.

Interesting, let say if your mechanic was right, the noise should disappear after you put your stock cable back, instead the noise happens in 3rd and 4th gear. I doubt that the problem is the grommet as we cut it out when we put the HR cable.
