So I have 41,000 miles on a 2008 g37s MT and this is the third time my slave cylinder went out WTF

 

I've had mine go out twice. I'm at 52K. 08 G37S 6MT

 

I presume it was covered under warranty for both of you?

 

Yup. Gonna buy the 4 yr extended warranty in a few months.

 

yes it was but still. Its getting annoying im gonna see if they will replace the whole transmission.

 

sorry for the noob question... but how can you tell if the slave cylinder is going bad?

 

Pretty much when you push down the clutch it gets stuck there and it won't come back up. Also it feels like you have 1/2 clutch to shift.

 

That could also be air or excessive moisture in the system or bad clutch master cylinder as well.

 

ahh, got it.... thanks.

 

how bout if the clutch is engage and as soon as you punch the throttle it jumps to 4-5k rpm then goes back down to 2k rpm and car starts accelerating?

 

Yes I just had this same thing happen to me last night was showing off my new G37S to a friend of my and was pretty embarassing when I punched the throttle the car revved up to about 7,000 rmp the clutch peddle wasn't coming all the way back up and clutch was still partially engaged which was really nice with the smell of burnt clutch in the car and my buddies smart **** remarks didn't help.
Now before this happened I had changed out the clutch fluid several times using the turkey baster method/ sucking it out of the clutch fluid reservoir and using synthetic DOT 4 brake fluid. Have had no issues with daily driving but none to happy about hearing about all these bad slave cylinders out there. I'm going to try to actually bleed the slave cylinder tomorrow to see if that solves my problem but highly doubt it

 

^^Doesn't sound like a bad slave. Sounds more like a worn out clutch and/or a pressure plate that's not applying enough pressure against the clutch disc. Unless, somehow a bad slave is preventing the clutch from being fully engaged. Typically a malfunctioning slave will prevent you from disengaging the clutch - PEDAL all the way to the floor, but clutch remains [partially] engaged.

How many miles on the car? How long as it been abused for? Maybe time to spring for a stage 2 clutch...

I doubt bleeding it will help. Good luck and let us know how it goes.

 

I don't quite understand the second part here, are you saying all your shifts feel like a 1st to 2nd gear shift?

 

^^I think he means half of the clutch pedal action is missing - ie pedal travel reduced by half.

 

Car only has 29000 miles on it. I'm the second owner of the car but don't think the previous owner abused it considering that the previous owner had the car in for routine maintenance like clockwork according to the Infiniti service reports. This was the first time I really was hard on the car.
