Hello everyone. I think I fixed my clutch problem.On clutch cylinder there is three fittings for air in and out. Mi e leak air whenever i pressed clutch. Of course I couldn't hear when I was inside the cab. So I had my dad helped me,he pressed clutch and I sprayed some windex and there was leak on all three so I replaced fittings greased throw out bearing agin. And now works fine. I have been driving for almost a month with no problems. Please let me know if this helped you. Thank you

Hello Did you ever fixed this problem. I have 2008 CHU 613 with this problem.I replaced sensors for turbo shaft speed, turbo temperature sensor, but problem is still there. Momentarily will lose boost and then goes normally for miles.This happens mostly up hills under load.
