how to fix P0700 code on Ford F-150 13th Generation (2015-2020)

Solution

1. Preparation

• Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, fluid pump.
• Disconnect the battery to prevent electrical shorts during repair.
• Ensure the vehicle is on a level surface and secure with jack stands if necessary.

2. Check and Replace Transmission Fluid

• Fluid Level Check:

  • Remove the transmission dipstick and check the fluid level.
  • If low, add the appropriate type of transmission fluid (consult the owner’s manual for the correct type).

• Fluid Change:

  • Place a drain pan under the transmission pan.
  • Remove the transmission pan bolts using a socket set and carefully lower the pan.
  • Clean the pan and remove the old filter.
  • Install the new filter and seal the pan with a new gasket, tightening bolts to the specified torque (typically 10-12 ft-lbs).
  • Refill with new transmission fluid through the dipstick tube using a fluid pump.

3. Inspect and Repair Wiring

• Visually inspect the wiring harness leading to the transmission control module and transmission for frays, breaks, or corrosion.
• Use a multimeter to test for continuity and proper voltage at the TCM connector.
• Repair or replace any damaged wiring or connectors as needed.

4. Reprogram/Replace Transmission Control Module (if necessary)

• If the TCM is faulty, purchase a compatible replacement.
• Use the OBD-II scanner to clear existing codes.
• Follow manufacturer instructions for programming the new TCM.
• Reconnect the battery.
