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

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is on a level surface and safely secured with jack stands if elevated.
• Disconnect the vehicle’s battery to prevent electrical shock.

2. Check Transmission Fluid

• Sub-steps:
  1. Remove the transmission dipstick.
  2. Wipe it clean, reinsert, and remove again to check the fluid level.
  3. If low, add the appropriate transmission fluid (Ford Mercon LV) until it reaches the proper level.
  4. Inspect the fluid's color and smell; if it’s dark or smells burnt, a fluid change is necessary.

3. Inspect Wiring and Connectors

• Sub-steps:
  1. Locate the TCM wiring harness.
  2. Visually inspect the connectors for corrosion, dirt, or damage.
  3. Use a multimeter to check for continuity in the wires.
  4. Repair or replace any damaged wiring or connectors as necessary.

4. Test and Replace Transmission Solenoids

• Sub-steps:
  1. Remove the transmission pan to access solenoids (may require draining transmission fluid).
  2. Disconnect the solenoid connectors.
  3. Use a multimeter to measure the resistance of each solenoid against manufacturer specifications.
  4. Replace any solenoids that are out of spec or visually damaged.

5. Reprogram or Replace TCM (if needed)

• Sub-steps:
  1. If the TCM is confirmed faulty, remove it from its mounting location.
  2. Install the new TCM, ensuring all connectors are secure.
  3. Reconnect the battery and use an OBD-II scanner to reprogram the TCM if required.

6. Final Steps

• Reinstall the transmission pan with a new gasket.
• Refill the transmission fluid if it was drained.
• Reconnect the vehicle's battery.
