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

Solution

1. Preparation

• Gather tools and parts.
• Disconnect the negative battery terminal to prevent electrical shorts.
• Raise the vehicle safely using jack stands if needed.

2. Check and Replace Transmission Fluid

• Tools Required: Transmission funnel, fluid catch pan, socket set.
• Check the transmission fluid level using the dipstick. If low, add the recommended fluid as per the owner's manual.
• If the fluid is dirty (dark or smells burnt), drain the old fluid using a fluid catch pan, and replace it with new fluid.
• Recheck the fluid level and ensure it’s within the correct range.

3. Inspect Wiring and Connectors

• Tools Required: Multimeter, wire brush.
• Inspect the transmission wiring harness and connectors. Look for frayed wires, corrosion, or loose connections.
• Use a multimeter to check for continuity in the wiring.
• Clean any corrosion from connectors and ensure all connections are secure.

4. Replace the Transmission Control Module (if necessary)

• Tools Required: Socket set, torque wrench.
• If the TCM is damaged or non-functional, remove it by unscrewing the mounting bolts.
• Disconnect the electrical connectors and remove the old module.
• Install the new TCM by connecting the electrical connectors and securing it with the mounting bolts. Torque the bolts to the manufacturer’s specifications.

5. Reconnect Battery and Test

• Reconnect the negative battery terminal.
• Start the vehicle and allow it to reach operating temperature.
• Perform a test drive to ensure that the transmission operates smoothly and the check engine light remains off.
