My truck slips out of drive into neutral and is hard into park because I had to remove the clip how do I adjust this back

sound like park neutral position switch is either loose out of adjustment or switch is broken.

1. Position the steering column transmission shift lever to PARK (P).
2. Apply the parking brake.
3. Raise the vehicle. Refer to Vehicle Lifting.

1. Position the transmission range select lever to PARK (P). Rotate the range select lever clockwise until it reaches the full mechanical stop position.

1. Slide the black retaining clip forward on the range select lever cable end. This will allow the white lock button to be pushed out.

1. Push the white lock button on the range select lever cable end out. This will free the metal core adjust body which is inside the cable end. Do not push the white lock button completely out.
2. Inspect the metal core adjust body on the cable end for dirt or debris that may restrict the travel. Remove any debris by washing the cable end, the metal core adjust body, and the white lock button with soap and water. If the travel of the metal core adjust body remains restricted after the cleaning, replace the cable assembly.
3. Lower the vehicle.
4. Ensure that the parking brake is applied.
5. Turn ON the ignition switch.

1. Move the transmission shift lever from PARK (P) to 1 and back to PARK (P) ten times.

1. Place the steering column transmission shift lever in the Park (P) position.
2. Turn the ignition switch to the OFF position.
3. Raise the vehicle. Refer to Vehicle Lifting.

1. Position the transmission range select lever to PARK (P). Rotate the range select lever clockwise until it reaches the mechanical stop position.

1. Push in the white lock button in order to secure the core adjuster body inside the range select lever cable end.

1. Slide the black retainer clip rearward over the cable end until it covers the white lock button. Lock the clip over the cable end.
2. Lower the vehicle.
3. Turn ON the ignition switch.
4. Ensure that all the transmission shift light positions (P. R. N. D, 3, 2, 1) engaged and illuminate. If you cannot perform this task, repeat the cable adjustment procedures.
5. Ensure that the engine starts in PARK (P) and in NEUTRAL (N) positions only. If the engine does not start in PARK (P) and in NEUTRAL (N), the Park/Neutral Position Switch may need adjustment.
6. Turn the ignition switch to LOCK.
7. Ensure that the ignition key can only be removed with the transmission shift lever in the PARK (P) position.
8. Start the engine and check the vehicle transmission shifting. The range select lever cable is properly adjusted if the steering column shift light positions are the same as the transmission engagements.

Look on top of the transmission and you will see a cable that is no longer connected to it's arm. Replace the missing clip.

Servo or band worn out, o.ring gone hard or clutch pack burnt out.

Put park brake on or block wheels, and shift into neutral (if possible), If not go to tranny and pop the cable off the tranny lever (pry off with screwdriver). Turn tranny shift lever, until it clicks twice, leave here for later adjustment. Follow the cable to the adjuster, pull out the flat steel retainer clip, pinch the sides to remove cable from bracket. Remove upper covers below the steering wheel. Remove kick panel below steering colomn. Remove cable from steering wheel shifter assembly (pry off and remove clip same as at tranny). Remove the side kick panel and follow cable along floor. You may find it easier to remove the driver seat (4 nuts on floor and wiring). Pull cable thru floor and replace. Reverse procedure to install. Lock the cable and clip at steering colomn, but leave the clip off at tranny. The tranny should still be in neutral. Now turn key to run and shift the shifter into neutral. At the tranny side cable there is a white square button, press in and lock cable to lever. install retainer clip. move shifter thru ranges and ensure it locks in park. Readjust if needed by pressing button and moving shifter lever on tranny.

Check your transmission fluid. Dont check it in park ! Check it in neutral! Read the dip stick.

It could be a bad ignition switch or bad starter wire from the starter switch, or the PNP is not adjusted correctly:

Here are instructions on how to remove and replace the PNP, but read over it to understand how to adjust:

Maybe try to press the brake pedal and run the gear shift throughout the full range of gears while the car is on level ground, and retry the starter to see if there is a faulty PNP adjustment.

Try to start in Neutral not Park, and jiggle the gear shift back and forth to see if the PNP is not adjusted right.

Good luck on this repair.

i would say the fine grinding was when you put it in park the output shaft was turning and the parking paw was trying to engage into park then the paw engaged into park but you say it rolled i am thinking that your problem is in the transfercase

It sounds like the linkage in the transmission has slipped. Check the linkage adjustment from the gear shift to the transmission. It sounds like it has slipped into neutral, and automative transmissions will not start in neutral.
Try moving the gear shift back and forth and have a friend see if the linkage, viewable from under the hood (though you may have to remove the air box first), is moving as well. If it is, disconnect the cable off the link and manually push the arm into park. Try to start the car. If your car starts, then this is definitely the problem. Go to your local transmission dealership for information on repair.

you could need a throttle linkage adjustment. first check to see if your ram will start in "park" and "neutral" only. if it starts in any other gear=faulty neutral safety switch. replace. ok, now check linkage for proper adjustment...with engine off and in park...remove intake housing..disconnect cableend from attatchment stud on your throttle body..slide cable off the stud (carefully)..verify that the transmissionthrottle lever is fully forward (idle) position..and verify that the lever on the throttle body is at curb idle pos..insert small screwdriver under edge of the retaining clip and remove..center the cable end on attatchment stud to within 0.04", or 1mm. install retaining clip onto cable housing..check cable adjustment..be sure trans throttle lever and throttlr body lever move in sync with each other.
