what causes a P0700 code in Ford F-150 13th Generation (2015-2020)

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to prevent electrical shorts.

2. Inspect Wiring and Connectors

• Remove the TCM cover to access the wiring.
• Check each connector for bent pins or corrosion.
• Clean or replace connectors as necessary.
• Reconnect the TCM and ensure all connections are secure.

3. Transmission Fluid Check

• Locate the transmission dipstick.
• Remove the dipstick and wipe it clean.
• Reinsert it and then remove it again to check the fluid level.
• If low, add the correct type of transmission fluid (consult the owner’s manual for specifications).
• Inspect the fluid color; if it’s dark or burnt, consider a fluid change.

4. TCM Testing

• Reconnect the battery.
• Use a multimeter to check the voltage at the TCM connectors.
• Compare readings to the specifications in the service manual.
• If readings are outside the normal range, replace the TCM.

5. Transmission Inspection

• If all previous checks are normal, perform a physical inspection of the transmission.
• Check for any damaged components, leaks, or signs of wear.
• Replace any faulty components as necessary, such as clutches or solenoids.
