Possible CSC failure. NEED ADVICE ASAP

kenchan · 12-10-2015, 10:21 AM

i mentioned this on another thread, but i think the csc prematurely wears out if u abruptly force the csc to work at high rpm. go easy on the clutch-in especially at high rpm.

well, besides tranny oil change.. and clutch fluid change ranger style.

Update: Just got my car back from the shop yesterday. I guess they're was air in the system, they bled the lines and everything is back to normal. Just need it to last me for a few months before until I start my turbo build.

Assuming it was air, hope it stays working, sometimes they will change fluids and it will be fine for another month or so.

So you're saying the CSC could still be bad and this is just covering it up?

May 2014. My clutch gets spongy and then goes to the floor. I drove a long way home in 3rd gear, no choice. I have it towed. They say the clutch fluid is dirty, change it, and it works. August, same year, same thing and had it towed both times. They bled the system and said air was in the line. September, same year, same story, this time it is the fault of the DOT. I needed GTR DOT, which they put in. Worked again. Late October, started going soft again. Warranty had expired the week before. Sold the car.

That's literally how the first part of my story went exactly. "The clutch fluid was contaminated so we replaced the master cylinder" then it got softer over the next couple months until it went to the floor. It's pretty stiff now. Like stiff enough to were I have to get used to driving it again aha. I just need it to last a few more months. So I've been driving my other cars and taking it easy on this one. How'd you manage to sell the car with the soft clutch? Now if the CSC fails wouldn't the clutch be stuck to the ground permanently until it was replaced? I'm not sure how replacing the fluid would get it going again.

Should I just bring it back and say it's feeling soft again? And have them take a look at the CSC I just don't want to wait and have this **** happen with someone in the car again or in traffic. It only seems to happen when I'm on the highway,

yep, i agree with array. it'll come back maybe not today, but in a couple of weeks. they need to change parts from all the read. just giving u a heads up so u dont go too far from civilization when ur clutch system fails again..

You haven't contacted the original repair shop yet to even ask them? But you wonder if you should get your lawyer involved?

Consider it a blessing in disguise with the price of some money out of pocket. Get an aftermarket CSC and you won't ever have to deal with a failed CSC again (with very few exceptions)

No they "fixed it" a couple weeks ago. It's up and running.

JARblue · 12-30-2015, 03:07 PM

So you're good?

If they didn't replace the CSC, just be prepared

Inspector71 · 01-04-2016, 10:10 AM

I have a little over 2 years on the 3 years or 36K miles, whichever comes first standard warranty. During that time I am buying an after market csc recommended by folks on this forum plus the stainless steel lines. At or near warranty expiration, I will have it replaced even if the stock one appears fine. When they go, they can go all at once. The only decisions I have left are based on recommendations by other members to go ahead and replace the master cylinder as well (is that necessary?) and many have recommended changing to a different clutch as well. Is that necessary? No, I don't race or drive the car hard. I'm an older guy loving his sports car.

I would recommend a new master cylinder when you replace the slave. If you are getting an aftermarket CSC, this may not be entirely necessary. I would go ahead and do it because the masters are prone to failure as well. My CSC had not yet failed when I replaced it with aftermarket at 50K miles, but at 70K miles I'm on my 4th master cylinder

No need to change the clutch unless you're unhappy with the stock one
