Mitsubishi Repair: car that doesnt move, clutch friction, 3000gt vr4

Question
I have a 93 3000gt vr4. I was driving on the interstate with the cruise control on; When I was getting onto an exit (onto another highway), I tapped the brakes to disengage the cruise control.  Nothing happened.  The master cruise switch did nothing.  I ended up pressing the clutch to coast to a stop on the side of the road.  Unfortunately, I didn't turn the engine "off" while doing this, so my transmission was bouncing off redline the entire time.  I was mostly grateful to be alive at the point however.  Once I was safely stopped, I was able to detach the cruise control cable, and then the car started normally.  It idles normally, however it does not move.  The clutch feels normal, it shifts normally, with no grinding.  I checked all the fluid levels, and everything seems  normal.  I'm about to take it into the shop - just wondering if perhaps you could provide some insight into what the issue might be.  Thanks!

Answer
Kate,
It's possible your clutch release fork is stuck, or even your clutch friction plate is complete worn and is slipping.  If all the friction material on the plate is worn, or the clutch pressure plate is not completely engaging (even though your clutch pedal feels fine), you will have no movement.  There is a slim possibility your front axles and transfer case had broken and are preventing movement, but that's very rare.

You will want a transmission shop to inspect your clutch, and your cruise control unit.  You are very lucky you were not in an accident and you should report that problem to Mitsubishi.  To kill two birds with one stone, you may want to have the dealership inspect and fix both problems.  The transmission on the 3000GT VR4 is very complicated, and the dealership would be the best qualified to work on it.  You can also ask to talk to the Service manager and tell him or her exactly what happened with your cruise control.
Good luck!
