Transmission does not shift into any gear

Hello there, it sounds like the neutral safety switch is not disengaging. Try checking down on the brake pedal, the brake pedal has a switch on it and because of its location down by your feet, the switches take a lot of abuse down there, the switch should click when you press the brake pedal, sending a signal to the ECM to release the safety neutral switch and be able to move the gear shifter. Check that first and let us know.
