how do I fix the P0700 code on my Ford Explorer Sixth Generation (2020-present)

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Ensure the vehicle is on a level surface, and engage the parking brake.
• Disconnect the battery (negative terminal) to prevent electrical shorts.

2. Inspect and Change Transmission Fluid

• Fluid Inspection

  • Remove the transmission dipstick (if equipped).
  • Check fluid level; add the recommended type of transmission fluid if low.
  • Smell the fluid; if burnt, a fluid change is necessary.

• Fluid Change Procedure

  • Place a drain pan under the transmission pan.
  • Remove the transmission pan bolts using a socket set.
  • Carefully lower the pan, allowing fluid to drain completely.
  • Inspect the pan for metal shavings and debris; clean or replace as needed.
  • Replace the transmission filter (if applicable) and reinstall the pan with a new gasket.
  • Refill the transmission with the appropriate type and amount of fluid as specified in the owner’s manual.

3. Repair Wiring and Connectors

• If damaged wires or connectors were found during inspection:
  • Cut and strip the affected wiring.
  • Use appropriate gauge wire to splice and solder connections, ensuring proper insulation with heat-shrink tubing.
  • Reconnect all connectors securely.

4. Replace Transmission Control Module (if necessary)

• If diagnostics indicate a faulty TCM:
  • Locate the TCM; it’s usually found near the transmission or under the dash.
  • Disconnect the wiring harness from the TCM.
  • Remove the mounting bolts and take out the old TCM.
  • Install the new TCM in the reverse order, ensuring all connectors are secure.

5. Battery and System Check

• Reconnect the battery and start the vehicle.
• Check for any error codes with an OBD-II scanner.
