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

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery to prevent any electrical shorts.

2. Address Transmission Fluid Issues

• Sub-step 1: Check the transmission fluid level using the dipstick. If low, top off with the correct fluid type (typically Mercon LV for Ford).
• Sub-step 2: If the fluid is dark or smells burnt, perform a transmission fluid change, draining the old fluid and replacing it with new fluid.
• Sub-step 3: Replace the transmission filter if applicable, ensuring that the new filter is seated properly.

3. Inspect and Repair Electrical Connections

• Sub-step 1: Remove the transmission control module connector. Inspect for corrosion, bent pins, or other damage.
• Sub-step 2: Clean any corroded connections with electrical contact cleaner and reconnect securely.
• Sub-step 3: If the wiring harness is damaged, replace it with a new harness.

4. Test and Replace Transmission Solenoids (if needed)

• Sub-step 1: Remove the transmission pan to access the solenoids. Drain excess transmission fluid into a clean container.
• Sub-step 2: Disconnect the solenoid connectors and remove the solenoids for testing.
• Sub-step 3: Test solenoids for resistance using a multimeter. Replace any solenoids that do not meet manufacturer specifications.

5. Reassemble and Reconnect

• Sub-step 1: Reinstall the transmission pan with a new gasket, torque to manufacturer specifications (typically around 10-12 ft-lbs).
• Sub-step 2: Reconnect the transmission control module and battery.
• Sub-step 3: Fill the transmission with the appropriate fluid level as per specifications.
