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

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to prevent electrical shorts.
• Ensure the vehicle is on a level surface and securely lifted if needed.

2. Check Fluid Level and Condition

• Using a dipstick, check the transmission fluid level.
  • If low, add the recommended transmission fluid type (check owner’s manual).
  • If fluid is burnt or contaminated, proceed to drain and replace it.

3. Inspect and Repair Wiring

• Visually inspect the wiring harness connected to the TCM and transmission.
  • Look for frayed wires, poor connections, or corrosion.
  • Repair or replace any damaged wiring as needed.

4. Test Transmission Control Module (TCM)

• Reconnect the battery and use a multimeter to test voltage at the TCM.
  • Verify that the TCM receives the correct voltage (typically around 12V).
  • If voltage is low, trace back to the battery and fuse panel.

5. Replace Faulty Components

• If the TCM fails testing, remove and replace it.
  • Disconnect the wiring harness and unscrew mounting bolts.
  • Install the new TCM and reconnect the wiring harness.
