Could be a failed CMC or a failed CSC. Each has its own symptoms. CMC failure usually presents as soft pedal feel, lack of pedal return, lack of pressure that can sometimes be restored by pumping or a combination of the above. CSC failure is much more sudden, with complete loss of pressure, and fluid often appearing under the tranny bell housing. Both parts are prone to failure. It should be obvious to the dealer which has failed. Regardless of the type of failure, give serious consideration to replacing the CMC with a heavy-duty CMC from RJM Performance ... and replacing the CSC with a HD unit from Z Speed Performance or Z1. If you simply replace the failed unit with another stock unit, you could face the prospect of another failure down the road. One of the forum members, JarBlue, is very familiar with CMC failures. He may add his impressions.
