I got the car used, clutch was pretty bad, then I burned it out more by learning to drive stick on it (my civic was an auto and the Z is NOT an easy car to learn on - yes it made me cry every time I stalled, I felt terrible about doing that to this car). I couldnt afford a clutch replacement, so I just drove on it for about a month. When I went to a shop to finally change it, he told me that "the flywheel is melted cause [I've] been driving on a bad clutch for so long" - he did show me the flywheel and it literally looked melted. They ordered the new clutch and flywheel. After an OEM clutch and OEM dual mass flywheel were installed, I started having problems.

- First of all, the chatter and loud noise. Much louder in real life than in the video. Noise completely goes away when I push the clutch pedal in. This sound was not there before they did work on my car
- Second, shifts are harder and sometimes grind now, never like that before they did work on my car.
- Third, the car shudders pretty bad when I turn off the ignition and you can hear a clunking sound (end of the video).
- Fourth, when in fifth gear and DECELERATING the stick pops into neutral and after that it is almost impossible to get it into fifth gear until I shift into another gear, then its fine. This same guy told me that its a syncro and that Itd cost even more to fix that..

Whats the problem here? I paid a ****-ton for this work to be done. And yes I did bleed the transmission and put new fluid in there. He did say that they had to drop the trans to get to the clutch and flywheel.

If you have time please watch the video and let me know, turn your volume up pretty loud and keep in mind it sounds a fair bit louder when not a video that's why its a concern. Also turn your volume up even louder at the end so that you hear the shudder and clunk when I turn off the ignition.
And, of course, the shop owner told me that all of this is normal for a car with 110k miles.

By the way, if I mess with the pedal and push it in a bit then slide out slowly a few times sometimes the rattle goes away even when I dont press the pedal. The car sits extremely quiet at idle at that point and I wish it was like that all the time. However if I push the clutch in again, same sound comes back.

PS. Been idling high around 1.5k last few days idk why, 700 or so is the usual
PPS. Sorry the title is unfinished and idk how to change that, should read Video of Clutch Chatter After Replacement

hmm the chatter is louder than my car but hey ever car is different. and the end part hmm on the turning off part.

 

I know that these cars are known for noises and chatter. But this is louder and it wasnt like that, that's the only reason Im asking

 

It is your throw out bearing. Was it changed as well? If not it is needed

 

I honestly am not sure, Ill try to call and check. Which one of those problems would the throw out bearing fix? chatter? Why would it only make the noise when Im not pushing clutch pedal in?

 

o.O Nice shot bud, right on the dot

sounds like you took it to a lame shop tbh.

Anyone that wont reccomend things to chage when youre in there are just looking to charge you more later on.. thats bad business man.

 

My grandpa's shop does bodywork and they recommended this shop to me. Although I feel like they did something wrong or didnt do enough, both my grandpa and dad tell me its just me and its a car with too many miles on it thats why its doing all this. Frustrating. How can I fix some of this stuff? How hard is a trans to drop down if I have access to a lift? Anyone know why the shifting is harder and why the car clunks and shudders at shutdown?

I mainly want to know if you guys think the shuddering and hard to shift is normal for a Z with 115k miles on it

PS: Throw out bearing came with the kit pre-greased and he said they installed it.. It definitely sounds like thats the problem but why would it make that noise if its new?

 

Sure, my trans chatters, but not that loud. It doesn't seem like any of those issues mentioned are normal for the Z's. I know it's more money, but you could take it to another shop and have them assess the install. Does the car or shifter shake more than normal during rpm climbs? It almost seems like something is off-centered, causing the shifter to pop, causing the shudder when shutting the car off, and the excessive noise engaging the clutch. Just my observation.

 

When i accelerate the shifter shuffles around in place idk how to explain it i figured it was normal, i cant really feel it if i hold the shifter but if i just look at it while accelarating it moves around, in any gear, ill try to catch that on video when my girl and i go out, ill just have her record. Theres two other problems that i havent mentioned:

If i shift into too high of a gear, for instance if i should be in third but i shift into fifth, the whole car starts vibrating and shaking like crazy, idk if thats normal but sometimes instead of second ill feel like shifting into third and if the rpms are below 2k it does that.

Second: if im in second or first and i Try to slow down with the brakes, the car jutters and jumps, making a whining noise.. Figured it was syncros but idk.. To give u an example the car lurches as if u let go of the clutch to fast when shifting.. Except im not even on the clutch while slowing down.. O.o this problem is why im too afraid to use downshifting to slow down.. I feel like im hurting the car.. And down shifting into first is impossible for me unless im going two miles an hour, and even then its really hard..

How much would an install assessment cost, approximately?

Thanks for the replies guys i do appreciate it

 

My car makes that exact same chatter noise... but nowhere near your other symptoms. I honestly dont think much of it... I know the Z's have loud trannys so it doesn't bother me too much. If it's the throw out bearing, I'll get that replaced and no more noise yay

EDIT: Here's a question for you guys. I had my transmission replaced by Nissan less than a year ago and it's been less than 16k miles (they issue a 1 year/16k mile warranty on their work). That warranty is still in effect. If I go into the dealer and complain about this throw out bearing noise, do you think they'll fix it without giving me bs about "it doesn't affect the car in any way blah blah" ?

 

Well considering you have to droP the trans that might not be such an easy or cheap fix in my eyes :O

 

Edited my post

 

They might give you the "thats how its supposed to be, because racecar" spiel, but id try it anyway. If yours is a anything like mine they have to notice it... Plus mention the throw out bearing and show the the vid i posted above if necessary. GL. Still looking for answers to my question

 

This sounds like a throwout bearing to me. I'm not an expert with this stuff but I've done a few clutch/flywheel changes already. The Z's definitely have a "typical" rattle noise like this but it seems like your's is amplified quite a bit.

Personally, I would take it back to the shop and have them listen to it. It's clearly not "normal" and if they want to keep you happy, they should at least give you some ideas and/or take a look at it again. Something isn't right.

Also, the jerking and bouncing of the car while slowing down, isn't right... unless your in 5th trying to slow down to 3mph - which I'm pretty sure you're not stupid enough to do. Maybe this place didn't reinstall properly?! Did they use new flywheel bolts? That's a must because they stretch after being torqued, should never reuse those old bolts.

Look at the 2nd post in this thread. Ask them if they made sure they lined up the indicator hole when reassembling. It may seem stupid, but I'm really not sure how things would "react" if you didn't line these up?! Another thought, I guess?!

DIY - Clutch Install Part II - JWT Clutch

Wish I could be of more help but if this was me I'd pull the trans/clutch/flywheel and look over everything myself.


EDIT: I just noticed that Jason said in that thread ^ that if installed improperly it will throw a CEL. Probably not the problem your having, but again, I'm just trying to throw out different options for ya.

 

I really do appreciate the post.. Ill take it to them again.. And show them the throw out bearing video if i have to. I wont even show them the car shaking cuz i know theyll want me to get a new trans installed in their shop. Im not mechanically inclined enough to drop the trans although i do have access to lifts and tools. Hopefully ill be able to do something like that as i gain experience working on my car. Just at basic right now, intake, exhaust, sensors, etc. thanks for the helpful post.

If anyone else has any more ideas please keep em coming.

 

Keep us updated man!

Remember, we all started somewhere working on cars! Take on more mods on your own (and follow DIY's on here) and you'll be pulling motors before you know it lol - well maybe not that far.
