Here's a few repeatable tests for anyone interested in verifying this for themselves. If you understand how a transmission works, it makes a million times more sense. Test 1: Clutch in and immediately back out- the input shaft doesn't have any time to slow down, so when the clutch re-engages, the input shaft (and clutch disk) are already spinning, so you hear no noise aside from clutch movement. Test 2: Clutch in and wait 5-10 sec- input shaft slows to a stop Clutch out- clutch disk engages and the input shaft jerks into rotation with the engine and you hear a faint clunk. Test 3: Clutch in and wait 5-10 sec- input shaft slows to a stop Clutch out gently (feather engagement) the clutch disk and input shaft are brought up to speed slowly, and you should hear nothing because there's no sudden acceleration on the input shaft. Test 3- repeat Test 1 and 2 and 3 with the engine off and parked. You will hear no clunk, because nothing is spinning. |

I agree that I have no clunking when the engine is off, however I still hear a clunk when I do a feather release.

clutch Engagement Issue?
I've had this for 25k miles now. When car got check before, the mechanic says it could be the clutch plate. They just told me to monitor it. I just lived with it up until then. So far everything is fine. Hopefully it will be gone after the time it will be change.

I noticed in the video that the idle was high, to me that meant that you just started it up from either cold conditions or where you live is generally is cold or its the first start of the day for your car. Any ways that sound is definitely not normal, and as a mechanic you should know that its not a normal sound, and clutch does not engage with a clunk sound like that in the video that was posted. What it actually sounds like is that the clutch was not bolted in properly and take it back to the dealer and tell them re-torque the clutch bolts and the fly-wheel bolts, because thats what it really sounds like LOOSE FLY-WHEEL or CLUTCH or BOTH

I'm going to post again because my first reply was first initial feed on the video and not going over everyone else's post, and what it sounds like is that this is a 2013 FR-S problem. Luckily I bought a 2014 Monogram and know its a 2014 model and not re-badged 2013 to 2014 because its a monogram so its more likely that I won't see 2013 issue. The point of this is that my 2014 does not make that sound bud
For me I'm noticing 2014 problem that might be engaging gears sometime is an issue because I think either I'm not pushing the clutch enough in so I grind my gears or the transmission fluid is low because of cold weather conditions so the condensity of the fluid is more compact in colder weather. |

You might just be hearing the clutch movement. You're still separating the plates when you depress the pedal, even though the engine is not running.
Another clunk has been found to be caused by the clutch pedal hinge brackets inside the cabin against the firewall. It's apparently more of a slight "pop" sound. |

I know this is reopening a thread from a while ago but I am having this issue after changing some of the suspension bushings in the car. If changing the fluid is recommended what have you guys ran in order to help out with reducing the noise and was there anything actually figured out as to what causes this issue? Should i just buy a new clutch and flywheel?

My car makes the same noise as this video here
They just called me to inform me they believe its the clutch springs and the solution is to replace the entire clutch assembly. I'm not entirely sure their correct considering how many different people have this issue with differing causes, what i've read mostly indicates throw out bearing. When i asked them if its covered under warranty, they informed me clutch is a "wear" item. Did anyone who has had this issue get it fixed? |

~~~~~~~~~~~~~~~~~~~~~~~~~~~ edit: I'm changing my tune on listening to the clip more carefully. I'll also admit to not reading the whole thread. @wheelhaus was on point. Normal operation.

Digging up an old thread but does anyone know what the culprit of this is? Just got a 13 brz and it clunks everytime I let the clutch pedal out, regardless if I hold it in for 10 seconds or so
