my Ford F-150 Fourteenth Generation (2021-present) won't go into gear what could be the issue

Solution

1. Preparation

• Gather tools: OBD-II scanner, socket set, transmission fluid, funnel, rags, and safety equipment (gloves, goggles).
• Ensure the vehicle is parked on level ground and the engine is off.

2. Check and Replace Transmission Fluid

1. Locate the transmission dipstick (for automatic transmission) or the fill port.
2. Remove the dipstick and wipe it clean; reinsert it to check fluid level.
3. If low, add the appropriate type of transmission fluid (refer to owner's manual for specifics).
4. If fluid is burnt or contaminated, proceed to drain and replace the fluid.
5. For draining, position a drain pan under the transmission, remove the drain plug, and allow the fluid to completely drain.
6. Replace the drain plug and refill the transmission with new fluid through the dipstick or fill port.

3. Inspect and Repair Linkage

1. Visually inspect the transmission linkage for any signs of damage or disconnection.
2. If damaged, remove the necessary components to access the linkage.
3. Replace any broken or worn linkage components.
4. Adjust the linkage according to service manual specifications to ensure proper engagement.

4. Test and Fix Brake Pedal Switch

1. Locate the brake pedal switch, generally found above the brake pedal.
2. Disconnect the electrical connector and test the switch with a multimeter to ensure it operates correctly.
3. If faulty, replace the brake pedal switch.
4. Reconnect the switch and ensure proper function by pressing the brake pedal.
