I have a 98 ls1 firebird I am having a issue with. A little less that a year (10K miles) installed a new stock slave, RAM clutch kit, speed bleeder and Tick performance master. Recently I noticed that as I drive the car more (it warms up) the clutch won't disengage all the way. I decided to try and bleed it to see if that fixed it. Dark fluid came out and I now have clean fluid with no air in the system. However, now the clutch wont fully disengage at all and once it runs for a few min it becomes impossible to shift. I dont see any fluid leaking and there is no air. Suggestions?
