Im in a bit of a pickle. Bought my 09 z51 a couple months back, and even completely stock, when shifting aggressively at high rpms the clutch would slip a little as it reengaged most noticeably when hitting 3rd and 4th. I never thought much of it and never did anything to fix. fast forward a couple months and i have done headers back, vararam and a healthy cam. While driving from colorado to kansas i noticed that when id jump on it in 3rd, once the revs were up around 5k the clutch would slip. luckily a buddy of mine with a z06 suggested checking/replacing the fluid. We opened up the master and fluid was low and looked like coffee. did the requisite ranger steps, took her for a test drive and VOILA problem solved. That night at the track, no slipping with RPM just in between shifts. pull back into the pits and coffee/fluid again. Since ive been back ive been trying to replace the fluid about once every week and always back to coffee.Everything was great with no slipping so threw on a wet shot and everything went great during tuning until the last pull when it sprayed and the clutch slipped. I wouldnt think the clutch would be completely toast yet as the car only has 20k miles but was wanting an opinion or any other similar experience before i just go and buy a new clutch and tick hydraulic setup. Thanks in advance

 

Hate to say it but contaminated clutch fluid by way of clutch dust is a normal characteristic of such vehicle

 

How big of a shot? I doubt the issue is wear, probably just too much torque for a stock clutch to handle.

 

Its only a 150 shot, but at sea level on just the motor is does the same thing at high rpm so I'm disinclined to believe it just can't handle the torque

 

Yeah sounds like it's just plain slipping for whatever reason.. time for a replacement
