Clutch failure tracking thread

[abiezerf]

Alright, with all these talks about clutch failures, I think it is a good idea to document who exactly it is happening to so we can find a pattern. Please post up your model year, mileage, any mods you might have, and what you are experiencing so we can try to see if there is any pattern. I'll update the OP as people post.

I'l start.

2012, 17.5k miles, intake, catted dp, catback, internals, 93 octane tuned by the freek.

Slipped in 4th and above at about 3500 rpm for a few weeks in Nov and Dec, been driving like a sane person since and have done several 4th gear pulls since without issue. Might be okay now? Not really sure

Damn, you got me worried now. I just hit 5200 on my way back home today, I am stock for now so I should be fine

[doctavus]

Damn, such low miles!

[someguy]

SomeGuy - 2010 - 43,000km - 3-4k rpm range in various gears - Mods in sig but basically fully bolted.

Also from my thread on the topic including logs of it happening:

5th and 6th gear acting up today, second time it's happened. First time was in 4th gear and the road might have been a bit slippery so I wrote it off even though it seemed weird. This time today though it was doing it relatively consistently and was able to grab a couple logs: http://someforum.net/datalogs/datalog172.csv http://someforum.net/datalogs/datalog174.csv

[Printman]

18,000 mi. mods in sig had it slip once last week in 4th around 4500 rpms doing a log. I went WTF but hasn't done it since so who knows if clutch is really going bad or just a fluke.
Been reading the clutch install how to's just in case might go ahead and order the ACT 6 puck when tax money comes in so I have it if it really is going bad.

[2011speed]

so far seems like only 2010 and 12

lol

2011 close to 31K miles. 50/50 E85 tune. 3.5 intake, 3 port, test pipe, internals, cpe TMIC gutted stock DP, egr delete, TB bypass.

Slipping in 4th and 5th mainly from 4-5K rpms but need to get logs to verify.

[blackms3_71]

Wow such low miles. I would check to make sure no oil or anything is getting on the clutch. I have an 08 with 60k fully bolted and i have never slippec

[rigor]

lost mine about 60k shit clutch

[blackms3_71]

Why do u feel the need to tell me that lol i wanted a big turbo with tax refund not a new clutch :/

Plus 60k wouldnt be too bad when u think about it i am putting down 100 more tq then stock

[jseams]

I have 9300 miles on mine and there have been several times that I thought the clutch was slipping... upon investigating and plugging a few logged instances into VD and datazap I found that it wasn't clutch slip it was wheelspin. You can see that there is a a direct correlation between rpm and vehicle speed and you can see the bump where I break loose. I've done this both in 3rd and 4th gear and there was never the typical tire "screetch" people often expect when you break loose... the only indication was a sudden rise in rpms and no increase in speed.

Anyhow, not saying that you folks aren't experiencing blown clutches just that you should be absolutely certain before you start to panic.

[someguy]

Breaking loose feels so much different than clutch slip...the tires don't always make noise, depends on road surface and heat and such. Mine if you look at the logs, rpm/speed don't stay constant.

Yeah, plotting your log shows you are really slipping. Pretty obvious especially in that second log.

However, I disagree that it always feels different; there are always threads popping up where people are asking "wheelspin or clutchslip"... I know, I'm guilty of this myself. lol

[specvspeedfreak]

Now I'm really confused. It didn't slip or spin? like it has before. Maybe I was just crazy... I don't know lol

some logs

Not sure what happened in datalog 3.. Edit: think it was a bump now that I think about it
datalog5.csv

datalog2.csv

datalog3.csv

[tornado842]

2013 11K miles. Slipped in every gear for a few days after trying out my new hoosier slicks. 334hp 377tq. After driving it softly for a few weeks it is no longer slipping. I had a 07 speed 3 for 40k miles without ever having the clutch slip. I have the new clutch/flywheel sitting in my garage waiting for this one to die.

[Sid3wayS]

@Ms3_Miami;

[Voltron]

There were a few cases local here.
A 2011 fully bolted w slipping around 30k
2012 w 3076 and 15k
2012 fully bolted, 7k

[2011speed]

Is there a correlation between all of these cases?

[blackms3_71]

Yeah big power lol

[abiezerf]

Lol I'll update the op in a few but modded cars seem to be the correlation. Oddly enough, I, too, did some more fourth and fifth gear pulls today and I did not slip. Not even once. I was going to adjust my SSP to the middle setting but now I think I'll leave it as is.

It's a silver pu conspiracy! lol

[pallen]

6800mi all stock. Just had my 2013 towed to the dealer. The pedal went to the floor while shifting normally. They let me look into the inspection hole and it was full of shredded clutch material. They will be submitting it to Madza.

[someguy]

Damn, that's a failure...not quite what this thread is about but madness. At least yours is almost guaranteed to be covered.

Yeah, they gave me the speech about the clutch being a 'wear item', but also acknowledged that it would be pretty hard to kill a clutch that fast even with the worst abuse. I'm over 40 and never driven anything but a standard. I know how to take care of a clutch.

[boostdmazda3]

seems like a pu problem. My stocker started slipping at 96k miles after the bnr.

[abiezerf]

Updated the OP, looks like the clutch slipping is a power issue mixed with the weather. Mine stopped slipping now that the weather has heated up. A few others have reported the same.

[Phoenix]

Mine took a dump Friday night. Was making a run through 6th and once I went to exit, the pedal worked normally, but the clutch would not disingage. Had to make it home rev matching and trying not to come to a stop. Waited a couple of hours and was still not able to get it into first with the engine on.

I suspect that the clutch was probably slipping just enough to cause a tremendous amount of heat and destroy the diaphram spring in the pressure plate.

I have 51k, 2011, internals, Sure 3" Aeros, internals and AP. Boost target is 18 psi. It's being towed to the shop today and will most likely find out tomorrow.

[CWP_MS3]

You need to find a better way to organize the OP @abiezerf;. Too difficult to read. I think bolt-ons matter less than whether or not they're custom tuned. Make them all follow the same format and space them or something. Like this maybe:

CWP_MS3
Miles - 29K
Mods - Bolted
Tune - E85
Description - started slipping when cold in 4th and 5th.

^^^ Just a suggestion.

[abiezerf]

Makes sense. Thanks. Updating now

[CWP_MS3]

Lol... So far the only consistency I'm seeing is mad power. Most people on that list are E85.

[someguy]

Not me...I'm self tuned on 94, approx in the 320-330 wheel torque range.

[kidlifecrisis]

I put down 291 whp on the mustang dyno at Powerplant Motorsports in Poughkeepsie, the consensus was that the dyno was pretty spot on with how a dyno jet would have read based on the other speeds that got on the rollers that day

[CWP_MS3]

How much torque?

[kidlifecrisis]

303

[adamizme]

Subbed... mine slipped badly on Christmas eve in 5th gear. For a few days after that, it was slipping in 3rd+. It hasn't slipped at all for a couple weeks now. Mods in sig. 38k miles. Tuned for 93 by Freek.

Guys post up accordingly so he can just cut and paste it to the OP. If you want to add more to it in your post, then do so, but make it easy for him to keep the OP up.

Updated the OP some more. I guess the Pu's don't like cold and torque.
