Hi i have a 2006 cobalt ss s/c i originally had the issue where it would lose clutch pressure on and off so i took it to transmission specialist and they replaced to slave, the master and the clutch and throwout bearing. Got it back and now its still loosi g pressure after about 20 minutes of driving it will work great then will go out untill i pump it a few times. They continue to say everything is good and they cannot find anything wrong. Any input would be greatly appreciated.

 

Well the only component you didn't replace was the line and unless it has a leak really the only thing it can be is it has some air in the line I would think. So they are trying to tell you everything is good even after you showed them the problem you are having?
