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

Solution

1. Preparation

• Gather necessary tools and parts for the repair.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Transmission Fluid Inspection

• Tools Required: Dipstick or fluid level gauge
• Remove the transmission dipstick and check the fluid level; add fluid if low.
• Inspect the fluid color and smell; if it is dark or smells burnt, consider a fluid change.

3. Wiring and Connector Inspection

• Tools Required: Multimeter, wire brush
• Visually inspect the wiring harness connected to the TCM and transmission solenoids for signs of wear or damage.
• Use a multimeter to check for continuity in the wiring; repair or replace damaged wires as necessary.
• Clean any corroded connectors with a wire brush and apply dielectric grease before reconnecting.

4. Transmission Control Module (TCM) Examination

• Tools Required: OBD-II scanner, socket set
• If additional codes are present, address those as they may indicate specific issues with the transmission.
• Check for any software updates for the TCM using the OBD-II scanner; if available, perform the update.

5. Transmission Range Sensor Replacement (if necessary)

• Tools Required: Socket set, torque wrench, new transmission range sensor
• Disconnect the electrical connector from the transmission range sensor.
• Remove the mounting bolts and carefully remove the old sensor.
• Install the new sensor and torque the bolts to the manufacturer's specifications (typically around 9-11 lb-ft).
• Reconnect the electrical connector.

6. Refill Transmission Fluid (if changed)

• Tools Required: Funnel, new transmission fluid (consult owner's manual for type)
• Add the appropriate transmission fluid through the dipstick tube until reaching the proper level.
• Start the engine and cycle through all gears, checking fluid levels again and adding as necessary.
