how to fix P0700 transmission code on Ford F-150 12th Generation (2009-2014)

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the vehicle's battery to prevent electrical shorts.
• Ensure the vehicle is on a flat surface and secure it with wheel chocks.

2. Fluid Inspection and Replacement

• Tools Required: Socket set, fluid pump, transmission fluid.
• Remove the transmission fluid dipstick and check the fluid level. If low, add fluid to the proper level.
• If the fluid is dirty or burnt, perform a transmission fluid change:
  1. Place a drain pan under the transmission pan.
  2. Remove the transmission pan bolts and carefully lower the pan.
  3. Drain the old fluid completely and inspect the magnet for metal shavings.
  4. Replace the filter if applicable.
  5. Reinstall the pan with a new gasket and torque bolts to manufacturer specifications (typically 10-12 ft-lbs).
  6. Fill the transmission with the specified type of fluid through the dipstick tube.

3. TCM Inspection

• Tools Required: Multimeter, socket set.
• Locate the TCM (usually found near the transmission).
• Disconnect the TCM connector and visually inspect for corrosion or damage.
• Use a multimeter to check for proper voltage and ground at the TCM connector based on manufacturer specifications. Repair or replace any damaged wiring.

4. Solenoid Testing and Replacement

• Tools Required: Socket set, multimeter.
• Locate and remove the transmission solenoids.
• Test each solenoid for proper resistance using a multimeter; replace any that are out of specification.
• Reinstall the solenoids ensuring proper seating and connection.

5. Reassembly and Final Checks

• Reconnect the TCM and battery.
• Start the vehicle and allow it to reach operating temperature.
• Monitor for any warning lights and ensure smooth transmission operation.
