how to fix P0700 code on my Ford Explorer Fifth Generation (2011-2019)

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the vehicle's battery to prevent any electrical short circuits.
• Ensure the vehicle is on a flat surface and securely lift it with jack stands if necessary.

2. Inspect and Replace Transmission Fluid

• Remove the transmission dipstick and check the fluid level; add Ford-approved transmission fluid if low.
• If the fluid is dark or has a burnt smell, drain the old fluid using a transmission drain plug or by removing the transmission pan.
• Replace with new Ford-approved transmission fluid, ensuring it's filled to the correct level.

3. Address Wiring and Connections

• Visually inspect the wiring harness and connectors for any signs of damage or corrosion.
• Clean any corroded connectors with electrical contact cleaner and reconnect securely.
• Repair or replace any damaged wiring as necessary.

4. Test the Transmission Control Module (TCM)

• Reconnect the battery and use an OBD-II scanner to check the TCM.
• If the TCM is faulty, remove it by disconnecting the wiring harness and unscrewing any mounting bolts.
• Replace it with a new or reconditioned unit, and reconnect all wiring securely.

5. Clear Codes and Test Drive

• Use the OBD-II scanner to clear the P0700 code.
• Test drive the vehicle to ensure the transmission operates smoothly and that the check engine light does not reappear.
