What part should I buy to fix the clutch problem? It goes all the way to the floor with little or no resistance and will not shift gears.

slave cylinder needs replaced

If you have a hydraulic clutch, it is conceivable that the fluid has leaked out. For areas of leakage check up under the dash where the clutch master comes through the firewall., or check down at the transmission at the clutch slave, which is the small cylinder on the transmission. You should also fill the reservoir immediately as well.

If yours is the adjustable type of clutch, then you need to have it ajusted immediately

If you would like to contact me again about this or other problems, feel free to do so.

The most likely cause of your problem is a hydraulic system problem. Your clutch system works off of hydraulic pressure and if there is a leak or it ran out of fluid it will cause the problem you have. The first thing to do is check the master cylinder to be sure that it is full of fluid. If it is not then you have a leak somewhere.
You could have a problem with either your master cylinder or slave cylinder.

Check Your Clutch Fluid It Just Like Checking Your Brake Fluid In The Engine Compartment. If Its Low You May Have Got Air In The Line Which Will Cause The Clutch To Feel Empty. Make Sure Its Full Then Get In And Push It 3 times and hold then get out and check it again seeing if its emptied the reservoir. Keep Adding until the clutch feels good again. make sure that after doing so there isn't any dripping off the bottom of the car which would indicate the line need to be repaired.

Next If The doesn't do it with the car off push the clutch very slowly and listen for any kind of suction sound near your feet. sometimes it leaks around the pedal. If you dont have any fluid on the floor board then all should be well.

Then fallow the line all the way to the transmission looking for fluid.
It is pretty easy to find as it doesn't dry.

Most vehicles use dot 3 brake fluid but your vehicle may differ check your clutch reservoir cap for specifications on fluid.
if it does take brake fluid do not spill it on your paint as it will take it down to the bare metal in no time.

I hope this helpful and look forward to hearing your results if you need more help.

bobby: what you are experiencing is a hydraulic failure. Either the clutch master cylinder, the slave cylinder or both have failed.
If you open the hood, look on the drivers side close the firewall.
There should be a white plastic cylinder with a cap on it.
Remove the cap and see of there is any fluid inside of it.
Note: The cylinder you are looking at has only one cap.
If the cylinder is low or empty, fill it with DOT 3 brake fluid
Look at the cylinder and you should see a line which attaches to the end of it. Follow the line down into the engine compartment.
It should travel over to a flexible hose which will go over to a smaller part on the transmission. Look at the hose and the part on the transmission, checking them for fluid loss. If you see no signs of leaks, get in the car and start pumping the clutch pedal. If the fluid loss was slow, the pedal will come back up, but it will be spongy.
If you look from inside the car, under the dash, follow the clutch pedal up to the place where you see a metal rod connecting to it. Follow the metal rod to the fire wall. Look and see if there are signs of fluid loss from there. You will need to get the air out of the hydraulics if you had just restored the pedal.
If so, the master cylinder will need to be replaced. Usually, I suggest replacing bothe master and slave cylinders because they are the same age and have the same wear and tear.
