Mitsubishi Repair: Clutch problem that now squeaks, mitsubishi 3000gt, clutch plate

Question
Transmission problem
1995 Mitsubishi 3000GT 6 cyl Front Wheel Drive Manual 110000 miles

I replaced the clutch 2000 miles ago. Now all of a sudden, you can not shift the car while the engine is on.. Will not go w/o forcing. Once you shut off the car and depress the clutch, no problems going between the gears. If you start the car with the clutched depressed, you will get a slight drag of the clutch and the car will want to pull forward. Master cyl and slave units are both new and working. Using the clutch seems fine when you push on it weather the car is on or off... just will not go into gear when the car is on (in any gear). I'm puzzled and need some advice. Thank-you. Steve

Answer
Steve,
You may have a bad throwout bearing or the clutch plate became misaligned.  It's also possible that synchronizers in your transmission have gone bad, and may not have anything to do with the clutch.  Check your transmission fluid level as well.  I'd recommend having a transmission shop inspect the tranny itself for possible problems.
Good luck!
