Clutch not working

Might be the clutch but unlikely if only confined to a single gear and it is usually possible to make a faulty clutch produce noise when stationary to help diagnosis.

If the clutch will transmit the full engine torque without slipping there is unlikely to be much wrong with either the centre plate or the cover. Problems with the release mechanism can often be felt through the clutch pedal and clearly be heard to be in sympathy with clutch pedal operation.

I suggest you check the transmission oil level and then look around for other possible causes if another "look" at the clutch produces no results. Auxilliary belt perhaps...

When you put in gear /handbrake off can you push it to move it [if no ] push in clutch ,will it move now ,if yes then clutch is ok if no then either clutch OR main drive gear locking nut in gear box has a problem.

If you have a cable operated clutch then check the engine mounts especially the rear mount or reaction rod on a transverse transmission.. If you had a clutch problem it would be there all the time and the indications are that it would be slipping , shuddering , grabbing and generally be a pain in traffic. I would be looking for a reason to allow the engine /transmission to get out of alignment and cause binding of the drive shafts . If front wheel drive check cv joints and suspension points . If rear wheel drive check for problems in the slip joint or "u" joints.

Could be throw out bearing.

Check fluid levels first before you do anything drastic.

Something on the clutch system failed, remove the transmission you will find your problem there

Sticking clutch throw-out bearing arm or linkage/cable, or pedal, so that throw-out bearing is just barely and intermittently touching the throw-out plate of the clutch. Depressing the pedal slightly engages the bearing to the plate causing positive drive of the bearing, quieting the noise. After running a while, the bearing moves sufficient distance to disengage. Next time it happens, with the vehicle stopped, in neutral and with the parking brake set, stick your toes under the clutch pedal and pull it back, see if the noise stops or changes..

Check the heat shield over your catalytic converter, see if it's loose.

sounds like the end of the cable is frayed ,but again i would really need to have a look myself to diagnose correctly

To reduce clutch disc/plate problems, avoid riding the clutch whilst driving, ie having ur foot on the clutch pedal when the engine is in operation, especially wqhen the vehicle is in motion. You see the clutch disc is sandwiched between the flywheel of the engine & the pressure plate. When the driver presses the clutch pedal, the sandwiching of the clutch plate is released, so therefore no drive is being transmitted from the engine to the road wheels. This gives an effect as if the vehicle is in neutral (engine can be revved, with no movement or propulsion of the vehicle). When the driver releases the clutch pedal, the clutch disc is now sandwiched tightly causing the drive to be transmitted to the road wheels which will now cause the vehicle to be propelled.

Clutch discs are only replaced when there are problemes with clutching in and changing gears. After constant pressing of the clutch, the asbestos material on the clutch disc after a period grinds down (clutch disc becomes thinner), which in turn will reduce friction characteristics when all the elements are sandwiched. This causes a slipping effect, preventing the drive from being transmitted to the road wheels efficiently. This causes other problems such as high fuel consumption, erratic engaging of gears, hard selecttion of gears, heavy vibration of the vehicle, stalling; just to name a few. In most cases an unusual smell of the clutch disc is observed.

Also just by resting ur foot on the clutch pedal while engine is running can be dmagaing too. You see the clutch release bearing rests on the pressure plate, so when the clutch pedal is pressed by the driver, there is a degree of friction being placed on the bearing because the pressure plate is always rotating with the engine. The clutch release bearing is stationery until the clutch pedal is pressed by the driver, which sends it into the moving pressure plate, so less pressing on the clutch pedal the less friction between the bearing and the pressure plate. Only operate/press/place foot on the clutch when necessary
