Turn the ignition to on position without starting car, set parking brake, have someone depress brake pedal and move gear selector lever through its range while you observe the linkage to verify it is working (you will have to look under the car on the left side of the transmission) if the selector lever on the side of the trans is clicking firmly into place in conjunction with the selector lever in the car than you are looking at internal damage, assuming fluid is full and in good shape, and all other connections are secure, burned clutches, stuck valve or other mechanical damage, could be torque converter but it would leak fluid.
