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

Solution

1. Preparation

• Gather tools and equipment: OBD-II scanner, socket set, multimeter, fluid catch pan, and transmission fluid.
• Ensure the vehicle is on a level surface and the engine is cool.

2. Transmission Fluid Check

• Sub-step 1: Remove the transmission dipstick and check fluid level.
• Sub-step 2: If fluid is low, add the appropriate type of transmission fluid (check owner's manual for specifications).
• Sub-step 3: If fluid is dirty or burnt, proceed to change the transmission fluid.

3. Replace Transmission Fluid (if necessary)

• Sub-step 1: Raise the vehicle using jack stands.
• Sub-step 2: Place a fluid catch pan under the transmission pan.
• Sub-step 3: Remove the transmission pan bolts using a socket set and carefully lower the pan to drain old fluid.
• Sub-step 4: Replace the transmission filter if applicable.
• Sub-step 5: Clean the pan and replace the gasket before reattaching the pan with a torque specification of 10-12 ft-lbs.
• Sub-step 6: Refill the transmission with new fluid through the dipstick tube.

4. Repair or Replace TCM (if necessary)

• Sub-step 1: If diagnostic steps indicate a faulty TCM, disconnect the battery.
• Sub-step 2: Remove the TCM from its mounting location (usually located near the transmission).
• Sub-step 3: Disconnect the electrical connectors and remove any mounting screws.
• Sub-step 4: Install the new TCM by reversing the removal steps and reconnecting all wiring.
• Sub-step 5: Reconnect the battery and clear the fault codes using the OBD-II scanner.

5. Final Checks

• Perform a road test to ensure proper shifting and operation of the transmission.
• Check for any reoccurrence of the P0700 code.
