My pacifica makes popping sound while shifting. it pops especially when i shift from park to reverse.

Have your motor mounts checked. With the hood open and the emergency brake on Watch for excessive movement with the engine while you put the engine in drive and then park. Also watch your drive axles to see if they are making the noise when you change the transmission from drive to reverse. Sometimes a bolt or a spark plug could be wedged between the motor and the frame making a high squeaking noise when the engine shifts position.

Check the CV axles first. They can pop out and cause your noise and won't keep the vehicle from moving in park. Replace the axle/s if they did.

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.

Yes! One is related to the other. The first is low/reverse solenoid malfunction and the second is an indication of range failure.

The can can't run. Why need to shift...?
If you want to shift anyway. Be careful if down or up hill the car will roll.
Here if need to shift away:
-Put key in ignition, turn to start, but do not start.
Now apply brake then shift.

Go to the Prindle switch where the cable meets the transmission and check if it has not unhooked. Move the shifter all the way to the Park position and adjust/tighten.

lincage rod inside the gear box will have bent it happens when to much preasure is applied commen for jamming up thow.

look for transmission shift interlock solenoid fuse.or a bad brake switch will cause transmission not to come out of park.

check your engine and trans mounts sounds like you have a bad mount allowing motor to shift up pop hood and look at engine while someone puts in gear see if engine comes up or kicks back it should only move slightly

all pacificas are auto and have a slap stick this might be due to have the spring that attacthes to the transmission it could be that the shifter might have to be replaced or adjusted or your transmission might be shot.
