Stuck in Park, replace Boo?

'94 TB LX V8.

I've contracted "Stuck in Park" disease. Brakelights work fine.

It just doesn't wanna shift out of P. If I turn key to OFF, I can shift to N, start car and run. But it won't shift noramlly out of P. When I try to shift from N to P, I get a clunk and the shifter stops in (maybe R).

Do I need to replace the idiot Brake-On-Off switch? Is there a test for it.

I took a peek looking for the Boo, couldn't see a thing. How to ya get to it?

I did a search on "replace BOO" and got all manner of goblety-gook garbage.

Thx,
Puddin

Most likely the shift interlock cable (or solenoid) is stuck.

Easiest solution is to pop the cable out of the clip at the shifter. Let me see if I can find a picture.

Remove the trim around the shifter (with the coin holders/cigarette lighter etc.) and you'll see this.

OK, what do I do after this stuff is exposed? Just make sure the cable is not broken, is connected to the solenoid, etc?

Thanks,
Puddin

Use needle-nosed pliers or a small screwdriver to pry the cable out of the plastic clip.

It's a system designed to lock the shifter in park if the ignition is in the lock position or if the brake pedal not depressed. It also prevents you from turning the ignition to lock to remove the key unless the shifter is in park.

It's a solenoid that acts on a steel cable. The cables stick and solenoids fail, so it effectively locks the shifter in park. Unless you feel like tearing apart the dash to get to the cable and solenoid, unhooking the cable from that white clip and disabling the system is the best alternative. You'll be able to shift out of park at any time - key in ignition or not; brake on or not. Just don't forget to put the car into park before you pull out your keys! ;)

Transmission Shift Cable

There's 2 different cables attached to the console shifter assembly..

When my "Transmission Shift Cable" broke on my 96 Cougar..The car wouldn't shift out of Park..

I grabbed another cable from the JunkYard..Installed it, and voila!..Fixed!..

Brandon is referring to the "Ignition Impulse Switch Cable"..One end of that cable is buried in the dash..

The "Transmission Shift Cable" goes from the bottom of the Shifter Console to the side of the Transmission case..

It would probably be easiest to start with the "Transmission Shift Cable"..

Then if that doesn't fix your problem..Check out the "Ignition Impulse Switch Cable"..

:thumbsup:

Well, I've never tried replacing it so what do I know? :tongue:

I had this problem about 5 years back. My dad unhooked the cable (before I was the only driver) but I eventually re-connected it (the last couple times my mother drove the car, she parked it but left it in drive! :facepalm:). It's been working fine since... :zdunno:

Your post lists:

1998 Ford F150 XLT

I am trying to fix a '94 TB LX 4.6L

Are you sure your advice about starting with "Transmission Shift Cable" is applicable?

If so, can you describe how to go about fixing it?

What about the BOO switch? (This gets thicker and thicker and ...).

Many Thanks,
P

If the brake lights work properly, then the BOO works. We'll ignore that for now.

The ignition interlock cable is known to cause fits in some cars (dunno about the MN12 specifically), but I've read where disconnecting it causes no problems in drivability save for the possibiity of turning it off and removing the key in not-park.

So I go out and fiddle around to see if I can get the console apart. I pull the ashtray. There is a cable visable. I hook a finger around it and gently pull it up. Appears to be 2 element electrical cable with a connector on the end. I'm pretty sure it wasn't connected.

What was it? How do ya get the console apart?

Thx,
P

There are two philips screws that go inside the lip of the console top against the arm rest. Open the arm rest door and you'll see them. Remove those two screws and lift the console top up off the console. There are a few snap clips securing it in place, so be careful when removing it.

The interlock cable is located at the front right of the shifter trim next to the air duct.

Thanks, I got it open, no problem.

2. Remove screws retaining transmission control selector dial bezel to transmission range selector lever and housing.

3. Remove screws retaining transmission range selector lever and housing to floorpan.

The transmission control selector dial bezel is still in your pics. That cable is BELOW it.

Try following steps 2 and 3 here.

Wrong side of the shifter. Move to the side closer to the front of the car.

Oooooops. I thought I was following Brandon's recipe. Evidently I need to follow Rayo's recipe.

And just disconnect the cable after it is exposed?

Thanks,
P

No problem with 2.

3. requires removal of the shift knob? I can feel the little slit with the u-clip in the shift knob, but I can't see it to work on it.

Normally, with a u-clip, part is exposed and ya go after it with needle-nose and a tiny screwdriver.

How do ya remove the idiot u-clip given ya can't see it?

Thx,
P

You should see it at the top right corner of the shifter. I had the same problem with mine and didn't need to take anything apart on the shifter. Look in between the shifter and the vent tube to the right of the shifter.
