I have a 2005 6-speed with about 65k on it. I replaced the clutch and flywheel approximately 6k miles ago. I am running a competition stage 4 six puck clutch with the ultra light flywheel. Over the past several hundred miles I have had issues grinding went shifting at high rpm (over 5500). I was getting the infamous clicking noise from my master cylinder so I replaced it and the slave cylinder. Still having the same issues. Overall it fells very notchy and not smooth shifting into all gears. I also recently noticed a squeaking sound coming from the trans at idle. When I press the clutch in slightly it goes away. I am assuming this is an issue with the throwout bearing. Can the synchros be bad? Am I going to have to replace the clutch again? Has anyone else had similar issues? I find it hard to believe the clutch, flywheel, and or throw out bearing is bad since it was all just replaced. Does anyone have thoughts?
