Did it move in gear? Usually when they start slipping its too late unless it slipping cause littel to no fluid.  Then you might get lucky sounds shot if it won't shift out of first but check your vacuum line on the passengers side make sure its still attached and follow it to the back side of the trans make sure the rubber is still on and not cracked or anything

You might check the filter also.  I have a van that done the exact same thing.  I changed the filter and never had trouble after that.  The filter was plugged...

Pop the governor cover off and see if the gear is apple cored.
