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

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery cable to ensure safety.
• Raise the vehicle using a jack and secure it on jack stands.

2. Fluid Change

• Tools Required: Socket set, transmission fluid pump, drain pan.
• Remove the transmission drain plug and allow the fluid to drain completely into the drain pan.
• Replace the drain plug and torque it to manufacturer specifications (typically 10-15 lb-ft).
• Using the transmission fluid pump, fill the transmission with the appropriate type of fluid as per manufacturer specifications (likely Mercon LV or equivalent).

3. Inspect and Replace Transmission Filter

• Tools Required: Socket set, screwdriver, transmission filter kit.
• Remove the transmission pan by loosening the bolts; expect fluid to spill, so have a drain pan ready.
• Take out the old filter and replace it with a new one from the filter kit.
• Clean the transmission pan and apply a new gasket to ensure a proper seal before reinstallation.

4. Check and Repair Wiring

• Inspect the wiring harness leading to the TCM for any kinks, frays, or disconnections.
• Repair or replace any damaged wiring as necessary.

5. Reconnect Battery and Clear Codes

• Reconnect the negative battery cable.
• Use the OBD-II scanner to clear the P0700 code and any other transmission-related codes.
