What is Up with These Clutches!?

Dealerships must love you. Lets just replace things without truly understanding what is wrong. I'm not arguing because I am not open to the possibility that the parts are failing again. I am pointing out the inconsistencies in the suggestions and my symptoms. Inconsistencies that no one has yet to actually explain. This is how you explore possible causes and discover solutions. I don't want to just fix this, I want to understand exactly what is happening in MY situation that coincide with the contradicting symptoms that I have. Do you know what else happened to all those people that got their master and slaves replaced and had their issue resolved? They all got new fluid too. Are you going to tell me that there is no way that couldn't have been the problem all along?

Here are the facts for my situation:

• No Fluid Loss
• Pressure only decreases after long periods of not shifting and while the car is driving. If it sits in the garage all night, it is still fine the next morning.
• Pumping the peddle after not shifting for a while returns pressure and pressure is consistent with regular usage in city driving.
• Flushing the fluid corrected an un-drivable situation already for months of regular/daily use and before that situation was corrected, the issue was relieved after only seconds of stopping and starting the engine.

If the system was leaking, I would be loosing fluid and a fluid flush would not 100% correct the problem for months and the actions that were taken to relieve the previous issues have no influence on the parts. This is why I am leaning on issues not related to the parts them self.

When people replace the CSC with an aftermarket, are ALL clutch issues resolved permanently? Are they replacing the master with an aftermarket too? Are they still using GT-R or equivalent fluids?

everyone that replaces the CSC also replaces the Master at the same time, it is a must, if they haven't then it will fail. There is no after market master, but an aftermarket CSC often reduces the chance of master failure, they go sort of hand in hand IIRC.

GT-R fluid is not a fix its just the dealers BS. Redline is what most will agree is the fluid that is needed.

your symptoms are consistent with master cylinder failure which takes place over a span of time. Either that or you're boiling your fluid all the time. But it is your car bro, we can all just offer suggestions.

The CSC/CMC issue has been discussed at length and fully explained in many, many threads on this forum previously. I'm am sorry that you could not take the time to search and understand for yourself. You have taken a very argumentative approach, which is why you're getting the curt responses. Replace your CSC with an aftermarket solution, replace the CMC with a new OEM one, put in some Motul RBF600 fluid, and be done with it. If you want to argue with that, then you deserve to have to deal with OEM CSCs failing for the duration you own the car
