Sounds more like a clutch slave cylinder.
Your pressure plate and throw out bearing in your clutch assembly are worn out...time for a new clutch
try to make sure the clutch pedal is all the way down before you change gear. in no way shape or form should you have to floor the clutch everytime you shift gears, however, if you are still grinding gears while flooring the clutch, and if there isn't that little bit of give on the pedal i'd suggest adjusting or replacing the clutch.
You will be unable to shift gears
The clutch will not engage ,you will not be able to shift./// the clutch will not (disengage ) making it almost impossible to shift gears
No. Clutch is what disengages the motor from the transmission. Shift would be changing gears. You should depress the clutch to shift from one gear to another.
You may have to have your clutch adjusted,
Either have air in your lines or you might need a new clutch plate.
you need a clutch that's all
It disengages the engine from the driveshaft allowing you to shift the gears on your transmission.
You have not pressed the Clutch peddle to change the gears!!
If it chatters when you start up I would be concerned. If some of the gears do not work, the clutch may be the problem.If the pedal is too low to the floor or gears strip or grind when you shift, it may only need adjusting.Fortunately, compared to automatic transmission, clutches are cheap to fix.
a clutch is a disc that pulls the drivetrain away from the gears so you can shift and select another gear.
