My '95 GSR has been humming along without problems until today when all of the sudden the car lurched while shifting. I turned around and came home only to find that now I cannot shift into any gear. In fact, if I push hard enough to get into gear, the car dies Now, the car shifts just fine when it's turned off. Then when I turn it back on while in gear, something under the hood makes a whining noise.

In the past, I had problems shifting and added Synchro Mesh and it worked great. But even then the shifting problems were gradual and never would it not go into gear. Do I have the same problem just more advanced or could it be something else? I do have the original clutch in it as well; 168,000 miles.
