My 2004 Honda civic clutch won't engage in all gears. Stick shift feels loose fluid levels are OK car was working fine this morning

If you are having trouble getting into gear, make sure the hydraulic clutch reservoir is full and bled. If the throwout arm moves fully, you may need a new clutch and pressure plate.

How do you bleed clutch? Clutch Pendle feels fine. Won't engage into gears proprly.

It may be a worn clutch or you have air in the system. I use a one-man brake bleeder to bleed the hydraulic clutch.
