my Ford Explorer won’t shift into gear, what could be the problem?

Solution

1. Preparation

• Tools Required: OBD-II scanner, socket set, multimeter, torque wrench, transmission fluid
• Safety Warnings: Ensure the vehicle is on a level surface and engage the parking brake. Disconnect the battery before working on electrical components.

2. Check and Replace Transmission Fluid

1. Remove the transmission dipstick and check fluid level; add fluid if low.
2. If the fluid is discolored or burnt, proceed to drain the transmission fluid.
   • Place a drain pan under the transmission pan.
   • Remove the transmission pan bolts using a socket set.
   • Allow fluid to fully drain before proceeding.
3. Replace the transmission filter if applicable.
   • Remove the old filter and install the new one, ensuring it is seated properly.
4. Reinstall the transmission pan, using a new gasket if necessary, and torque bolts to manufacturer specifications.

3. Inspect Transmission Linkage

1. Locate the transmission linkage under the vehicle.
2. Visually inspect for any signs of damage or disconnection.
3. If damaged, replace the linkage with a new component.

4. Test and Replace Brake Switch (if necessary)

1. Locate the brake switch near the brake pedal.
2. Use a multimeter to check for continuity when the brake pedal is pressed.
3. If the switch is faulty, disconnect the wiring harness and remove the switch.
4. Install the new brake switch and reconnect the wiring harness.

5. Reconnect Battery and Test

1. Reconnect the battery terminal.
2. Start the vehicle and check if it now shifts into gear properly.
