Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is on a flat surface and securely elevated if needed.
• Disconnect the battery to avoid electrical shorts.

2. Check and Replace Transmission Fluid

• Tools Required: Socket set, fluid pump, transmission fluid.
• Inspect the transmission fluid dipstick (if applicable) and remove the filler plug.
• Use a fluid pump to extract old transmission fluid and dispose of it properly.
• Replace with the manufacturer-recommended transmission fluid type, typically Mercon LV for the Ford Explorer.
• Recheck the fluid level after filling and run the engine to circulate the fluid. Adjust as necessary.

3. Inspect and Repair Wiring/Connectors

• Tools Required: Multimeter, wire brush, electrical cleaner, heat shrink tubing.
• Visually inspect the wiring harness for frays, cracks, or corrosion.
• Disconnect the TCM connector and clean using electrical cleaner to remove any debris or corrosion.
• Repair any damaged wires using appropriate electrical repair techniques, including soldering and heat shrink tubing.

4. Test and Replace Speed Sensors

• Tools Required: OBD-II scanner, multimeter, torque wrench.
• Locate the vehicle speed sensors on the transmission (usually near the output shaft).
• Use a multimeter to check the resistance and operation of the sensors.
• Replace any faulty sensors with new ones, ensuring to torque the bolts to manufacturer's specifications.

5. Reconnect Battery and Test Drive

• Reconnect the battery once all repairs are completed.
• Start the vehicle and ensure the check engine light is off.
• Conduct a test drive, monitoring for any abnormal transmission behavior or return of the P0700 code.
