how to fix P0700 code in my Ford Explorer Sixth Generation (2020-present)

Solution

1. Preparation

• Tools Required: OBD-II scanner, socket set, torque wrench, fluid pump, transmission fluid
• Ensure the vehicle is on a level surface and the engine is turned off before starting the repair.

2. Address Transmission Fluid Issues

• Sub-steps:
  1. Remove the transmission dipstick and check the fluid level.
  2. If the fluid is low, add the appropriate type of transmission fluid (consult the owner's manual for specifications).
  3. If the fluid is dark or has a burnt smell, perform a transmission fluid change:
     • Raise the vehicle using jack stands.
     • Place a drain pan under the transmission pan.
     • Remove the pan bolts with a socket set and carefully lower the pan.
     • Replace the transmission filter if applicable.
     • Clean the pan and replace the gasket.
     • Reinstall the pan and torque bolts to manufacturer specifications (typically around 10-12 ft-lbs).
     • Fill the transmission with new fluid using a fluid pump through the dipstick tube.

3. Repair Electrical Issues

• Sub-steps:
  1. Inspect the wiring harness connected to the TCM for any signs of damage or corrosion.
  2. Clean any corroded connectors with electrical cleaner.
  3. If damaged, replace the wiring harness or connectors as necessary.
  4. Reconnect the TCM and ensure all connections are secure.

4. Test Transmission Control Module

• Sub-steps:
  1. With the OBD-II scanner, clear the P0700 code and any additional transmission codes.
  2. Start the engine and take the vehicle for a test drive to ensure proper shifting and operation.
