Chevy Cavalier Transmission problems

I have a '97 Chevy Cavalier Z24 w/2.4 engine. When I shift into gear it kills the motor. When I unplug the tork converter, it will run but not change gears. All cylanoids have been replaced. I jack up the car and plug up the converter and shift into gear, the front wheels will turn but will not shift.

Could you help me with what is wrong?

Thanks...
