Sounds like your shift cable has gotten out of sync, If this is the case, you take the shify cable loose from the link on transmission, then shift link to park position , then adjust cable to line up to the link and rehook. I don't know exactly how your set up looks but the procedure is the same on most cars.

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.

Sincerely,
Michael Scott
