transmission clutch problem

Check the fluid level in the clutch master cylinder...simple to do and does not cost a dime!!

There are several possibilities that can cause your symptom. Low fluid leve, air in the system, clutch pedal geometry changed / Broken, or even the clutch pressure plate starting to fail causing it fail to release properly. My sugestion would be to take it to a local shop you trust and have them diagnose the issue. That way you dont waste your time and money on attempted guesses.
