Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, transmission fluid, funnel, rags.
Ensure the vehicle is on a level surface and the engine is cool. Disconnect the battery to prevent any electrical issues.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and pull it out.
2. Wipe the dipstick clean and reinsert it to check the fluid level.
3. If the fluid is low, add the appropriate transmission fluid (consult owner’s manual for specifications).
4. If the fluid is dark or has a burnt smell, drain the old fluid by removing the transmission pan.
5. Replace the filter if applicable, and clean the transmission pan before reinstalling it.
6. Refill with new transmission fluid to the correct level.

3. Inspect and Adjust Transmission Linkage

Sub-steps:
1. Locate the transmission linkage and visually inspect it for damage or misalignment.
2. Adjust the linkage according to the manufacturer’s specifications to ensure proper engagement.
3. Secure any loose connections or replace worn components as necessary.

4. Test and Replace Transmission Solenoids (if needed)

Sub-steps:
1. Locate the transmission solenoids, usually found inside the transmission.
2. Use a multimeter to test the solenoids for proper resistance values as per the service manual.
3. If any solenoids are faulty, carefully remove them and replace them with new ones.
4. Reassemble and reconnect all components.

5. Recheck and Test Drive

After performing the aforementioned repairs, reconnect the battery and start the vehicle.
Take the F-150 for a test drive to ensure the jerking during shifting is resolved.
