Lincoln Continental No Shift From Park

Q. Hi Vincent. I have a 1999 Lincoln Continental with the 4.6 liter V-8. The mileage is 113,000. I have a transmission problem. After driving 20 minutes of combined in traffic and highway, I stopped the car in a parking lot for about an hour.

When I tried to drive off, I could not get the shifter from P to R . The side knob would not move. I tried with and without park and foot brakes.

I turned off the engine and returned the key switch to the 1st (accessory) position, pressed the foot brake and pressed the side knob on the shifter. This time it moved and I was able to move to the shifter from P to R to N . Then I was able to start the car and select normally until I wanted to stop again. Whenever I select P . I have to go through the same procedure.

This problem has not happened before. I had the transmission oil changed at 103,000 miles. There are some other peculiarities with the brain on this thing, such as refusing to recognize the right rear door being closed, warning of low engine coolant with plenty in the reservoir and displaying low tire pressure warning with all tires okay. These problems are intermittent, but annoying.

The cruise has not worked for a while.

Is there anything I can do (being an appliance service tech) or is it a job for a dealer?


A. This is a problem with the Shift Interlock System and not the transmission. Bet you’re glad to hear that. The Shift Interlock System requires the key to be in the RUN position and the brake pedal depressed in order to shift out of PARK.

This is to prevent possible vehicle runaway.

There are a couple of possibilities here. The first is the Brake Pedal Position (BPP) switch. You can usually tell if this is bad if you have no brake lights at all.

Another possibility is a bad Shift Lock Actuator or Shift lock solenoid, located under the console.

First thing to do is check fuses 28 and 32 in the fuse box, if you haven’t already done so, and make sure they are good.

To check the BPP switch, check for power at the light green/red and light green wires with a test light with the key in the RUN position and the brake pedal depressed. If you have power there, then check for power at the light green wire at the Shift Lock Actuator.

f you have power at the light green wire at the Shift Lock Actuator, ground the black wire. If you hear a click, then you have a bad ground and it needs to be repaired. If not, the Shift Lock Actuator is bad and needs to be replaced.
