ok this happened i was out of work on saturday, and when i was on the car i noticed that the clutch was half way down i can turn on the car but, the gears dont go in. i also put the car in reverse and tried to turn it on and it would roll back i also tried in first and and the car rolled forward. <<(the car was off when i put it on gear then tried to turn it on) so should i replace the clutch or what could be the problem? my car is an 87 RX7 N/A :( :crying:

check for leaks on your clutch master cylinder .
looks like you have a leak or just dont have put fluid in it.
