Radio quits when taken out of park or neutral

Sounds like a transmission valve body failure. Could be the solenoid as well, you might as well replace that as long as you're in there. Is the check engine light on? Some auto parts stores will scan it for free.

check that 4x4 transfer case is not in neutral --is selector cable connected lts known to rust out --neutral safety is safety upon starting wont stop gear engagement-- check and test the tcc solenoid -torque converter and the tcm for possible failure

At the risk of going to the offensive, sometimes it's the simplest thing - you ARE putting it in neutral, at a stop, engine running, with the brake pedal pressed, when trying to shift out of 4wd, yes?

2) Check for blown fuse for 4x4 shift module

3)This sounds dumm, but worked on my wife 99. I took it to a school parking lot, put it in reverse, floored it and pulled on the lever and it popped out of 4x4

4) The shift motor is bad. Replace it.

Hope this helps.

Sounds like the reverse band or servo has gone out. Transmission shop needed for a confirmation.

Does it shift to 4wd high range ? If so then shift to 2wd . What is going on here is the transfer case motor is stopping due to the motor position sensor has gone bad which means that you replace the transfer case motor assembly. But if you wish to make it a 2wd for awhile then remove motor and manually turn shaft . This can be done by raising and supporting rear axle truck in park remove motor turn shaft slowly with pliers and rotating the play in drive shaft. There are stamped markings on back of case showing gear positions..

Do you have the extra shift lever on the floor or the "shift on the fly" electric selector? My 1999 only needs to be put in Neutral(with brake pedal pressed) for the Low range and the shift from 2wheel drive to 4wheel high is seamless with the Electric selector.

You might try putting the truck in reverse for a couple of feet, then to Park, and back to Neutral or Drive. Then use the Electric selector. Your year model may require a foot on the brake.

Ford has a style of selector that uses 1 wire to the Shift servo for all the drive ranges. There are resistors in the selector switch with each position making a different voltage. If the LED backlit bulb in the selector is dirty, it can throw off the voltage. I understand that the best access to the selector switch is through the opening for the radio. Once the radio is removed there are 2, 1/4inch screws holding the selector to the dash.

You can replace the selector or attempt to clean it as access is possible by removing 3 clips on the part. This made the LED changeable by providing access. There is a spring and checkball which makes the selector click into place and stay where you put it.

You can also try to clean the connections on the plugin for the selector with Electronics spray. Thats all you may need if you can jockey around the spray can to squirt the terminals on the selector switch.

With luck, my opening instructions may solve your problem. It is possible your mechanical shift linkage for the Park,Reverse,Neutral,Drive has too much play in it and an interlock is just not lining up. If you have another type of 4x4 with the extra lever on the floor there are different instructions.

I hope you feel my information was very helpful and complete. You can contact us again for more help.

You can shift between 2Hi and 4Hi when the truck is moving. Just let off the gas and shift it. But in order to shift to Neutral or 4Lo you need to stop the truck and shift the transmission into neutral then shift the transfer case.

Shifting to NEUTRAL
To shift the transfer case to NEUTRAL, first make sure
the vehicle is parked so that it will not roll:
1. Set the parking brake.
2. Start the vehicle.
3. Connect the vehicle to the towing vehicle.
4. Put the transmission in NEUTRAL (N) or have
the clutch pedal pressed for vehicles with
manual transmission.
5. Shift the transfer case to 2HI.
6. Simultaneously press and hold the 2HI and
4LO buttons for 10 seconds. The red NEUTRAL
light will come on when the transfer case shift to
NEUTRAL is complete.
7. Shift the transmission to REVERSE (R) for one
second, then shift the transmission to DRIVE (D)
for one second or FIRST (1) for vehicles with
manual transmission.
8. Turn the ignition to OFF.
9. Place the transmission shift lever in PARK (P) or
FIRST (1) for vehicles with manual transmission.
10. Release the parking brake prior to towing.

************************

Shifting Out of NEUTRAL
To shift out of NEUTRAL:
1. Set the parking brake and apply the regular
brake pedal.
2. Start the vehicle with the transmission in PARK (P)
or FIRST (1) for vehicles with manual transmission.
3. Press the button for the desired transfer case position
(2HI, 4HI, AUTO 4WD or 4LO).
4. Put the transmission in NEUTRAL (N) or press the
clutch pedal for vehicles with manual transmission.
5. Shift the transmission lever to the desired position.
After the transfer case has shifted out of NEUTRAL,
the red light will go out.
6. A re-engagement sound is normal when shifting out
of NEUTRAL.

the shift cable is the problem,probably needs adjustment

See if u have brake lights. This is what energizes the shifter solenoid. There are 2 fuses u can check both are in the under dash fuse panel. Fuse 23 (15amp) and fuse 26 (7.5amp).
To get it out of park turn igntion switch on stopping just short of engerizing the electronics then u should be able to get it out of park and into neutral.
