A likely cause is the brake pedal switch. It is on the brake pedal shaft. The switch must close when you step on the brake to shift the transmission from Park to other gears. The switch itself can be bad and must be replaced or one or more wires to the switch may be broken. My 1997 Ford Thunderbird would not shift out of Park until I found a broken wire and reconnected it. The entire switch can be removed to remove small broken wires from the switch that cannot be reconnected. Longer wires can then be inserted into the switch in order to splice the switch wires to the car wires. The correct size Crimp connectors and a Crimping tool would be good for a wire splice. Wrap the splice with rubber tape, not vinyl plastic tape. DISCONNECT THE NEGATICE GROUND CABLE TO THE BATTERY BEFORE DOING THE WORK. RECONNECT AFTER THE SPLICE IS COMPLETE.

Why does my dodge Dakota not shift into gear It will not come out of park And the brake lights arent working either. Could there be a connection?

There is what is called a brake sensor. This sensor has to engage to sent a signal to the transmission to release the pawl so that you can shift it. Replace the brake pedal sensor. It is usually on the top of the pedal arm upward under the dash. This will also cause the brake lights not to work. Good luck.

Check fuses, If brake lights do not work, transmission will not shift out of park. Brake light circuit is common to shift interlock. That's why you must step on brake to release interlock prior to shifting out of "Park" If stop lights are not working interlock will not release.

The shift mechanism is only allowed to move from park if and when the brake pedal is pressed. Possible causes are, faulty brake pedal switch, shift interlock solenoid, wiring, or broken shift button. Possible shift linkage or transmission problem. Find the procedure for "bypassing or overriding the shift interlock" for further diagnosis.

Why does the automatic transmission not come out of park on a 1995 Lincoln Continental brake pedal is pushed but the shift lever will not release from park position?

If the vehicle is parked on a hill and the weight of the vehicle is being held by the parking gear you may find that it will be difficult to shift out of park. I suggest using the parking BRAKE to hold the weight of the vehicle while parked. Set the parking brake BEFORE you put it into park, or at least before you remove your foot from the brake pedal. That way you are having the parking brake hold the weight and the transmission becomes the backup for holding the vehicle. It should be a lot easier to get it out of park then.
