Oh that's right, I should know this since I had to remove the slave cylinder on my S2000 to remove the clutch delay valve.. *hits palm against forehead*

 

I saw in the history the service advisor pulled up on my car my slave was replaced around 20k, customer complained could not get car into first gear. It seems like a common problem, still happens on 08's, although I hope not as much!

 

lol, i thought as much, dont worry iv been there many times myself...

This is not a normal or common occurrence, if you browse through 1st gen MTs you will find many ppl on their original clutches and cylinders without any problems.

The biggest issue imo is when ppl do not change out the clutch fluid that over time looses its properties and cause slave cylinder problems and at times keeps the clutch from disengaging properly, maintain your car properly and you guys should be fine for a long time on these cars, they are built tough

 

well I ended up haggling with the dealer until they agreed to do the service for 500 bucks even, since another shop was gonna charge me around 375 i'm fine with giving the dealer the extra 125 to have a loaner for a week while they work on it and i have their 12 month 12,000 mile warranty on the part. I like how they tried to sell me on the extended service plan which is a bunch of horse crap lol

 

^ hahah i knew this was coming considering how they were haggling with you, good decision, the extra $100 will insure a warranty and will have the work done by someone who has hopefully done this befoe. Keep us posted

 

^ thats exactly what I was expecting, but they're charging me it says for 3 hours of labor but they need my car til monday or tuesday... maybe they don't know what they are doing LOL.

 

I have been a Nissan/Infiniti fanboy since owning my first car, a 95 Maxima. My Parents and brother have all owned Maximas and G35s. It is extremely upsetting to me that Infiniti did not comp you in this case, as they have with our family on many other issues--a few AFTER warranty has expired. Once the work is done, I would try to hit Infiniti corporate again. Say you've been a loyal customer and have steered friends and family into buying Infiniti, yadda yadda. It has always worked for us. And it is so suspicious that there was a recall on this part and that failure of a slave cylinder is not at all common this early.

 

^good looking out, thats what i was thinking of doing, calling them and trying to see whats going on, now my concern kind of right now is that it is tuesday and I have yet to hear from the dealer since i agreed to go ahead with the repairs on friday, I don't think it takes a few days to do some work that i'm only being charged 3 hours of labor for

 

Well the work itself should be around 2-4hrs but they probably had to order the part which would have arrived monday or today since you dropped it off friday, then they can only work on your car in the order that it came in, so you MIGHT be later on in the list.

Dont worry you should have your car tonite or tomorrow.

 

picking my car up once I shower, can't wait to pick up my 35, the 25 is cool because it gets good mileage and its automatic but nothing can top the fun you have in a 6MT!

 

^ no doubt about that!! enjoy and keep us posted after a few miles if you have any problems. Also make sure your invoice lists the 12mo/12000mi warranty on labor and parts.

 

Hi everyone,

I know I'm bumping a way old thread, but I'm having slave cylinder issues on my 07 G35S Sedan and could use advice.

Right before my warranty expired (so Feb 2011 or Feb 2012?) my slave cylinder was replaced. It's now 69k miles, and I need another one. I called Infiniti and my VIN doesn't register any recall, even the "voluntary" one discussed here, so I'm going to be on the hook. I won't be going to the dealer, who wants $1100, unless folks have any ideas how to push the issue?

But instead of an OEM part, should I replace it with something more robust that will last more than 3 years? Recommendations?

Thanks!

 

The only alternate part is the zspeed motorsports metal slave cyl, the only drawback it requires more frequent fluid changes (http://www.conceptzperformance.com/C...on.php?II=5174)

I see now z1 motorsports offers a kit that eliminates the need for it altogether: http://www.z1motorsports.com/g37_370...oducts_id=7340

I don't know of anyone who has tried this yet though. I read from some its a bitch to bleed it with that kit on it but not a lot of feedback out there since it's so new.

These do not require any more frequent fluid changes that the original, Either should be done at least twice a year to keep the fluid clean, Just normal maintenance and very simple to do.

 

Well to me, that's a little misleading, inasmuch as basically every clutch fluid reservoir on nearly every other manual tranny car out there on the road runs most of its life perfectly fine with less than 'clear' fluid and does not experience the kind of BS issues we see occurring here. And where oh where, in the factory maintenance schedule, including the premium schedule, or even the factory service manual, does it say to replace the clutch fluid twice a year????? I'm not saying I don't appreciate having clear fluid; heck, who wouldn't? It's just that most cars are not so ridiculously sensitive to dirty fluid; to the point that this appears to just basically be a bad design if it is indeed what's causing failures.

I guess my bottom line is this: I am sure the Z1 product is indeed superior to the factory unit, BUT if it still requires a full fluid change twice a year to be considered warranted and reliable then (frankly) . . . wtf? Perhaps this over-the-top clutch fluid servicing is the real genius here, and not so much the hardware. I mean, if I were willing to replace my fluid twice a year, then maybe that alone would work with the factory original units and thereby spare me the expense (ouch) of the upgraded parts.

Has there ever been a long term comparison test for longevity and reliability between the factory stock system vs. the Z1 aftermarket setup when both were subjected to a strict fluid replacement regimen of twice-annual fluid replacements?

Thoughts anyone?
