how to fix P0700 transmission code in Honda Pilot Third Generation (2016-present)

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery cable to prevent electrical shock.
• Ensure the vehicle is on a level surface and securely raised if needed.

2. Check Transmission Fluid

• Remove the transmission dipstick and wipe it clean.
• Insert the dipstick back into the tube, then remove it again to check fluid level.
• If low, add the recommended transmission fluid (Honda ATF DW-1) as needed.

3. Inspect Electrical Connections

• Locate the TCM and check all associated wiring and connectors.
• Disconnect the connectors and inspect for corrosion or damage.
• Clean any corrosion with electrical contact cleaner and reconnect securely.

4. Test Transmission Control Solenoids

• Remove the transmission pan if necessary to access the solenoids.
• Disconnect the solenoid connectors and use a multimeter to check resistance values against the manufacturer specifications.
• Replace any faulty solenoids identified during testing.

5. Replace TCM (if needed)

• If diagnostics suggest TCM failure, remove the TCM from its mounting bracket.
• Disconnect the wiring harness and any associated connectors.
• Install the new TCM by reversing the removal steps and ensuring all connections are secure.

6. Refill Transmission Fluid

• If the transmission pan was removed, replace the gasket and reinstall the pan.
• Fill the transmission with the correct type and amount of fluid.
• Start the engine and allow it to reach operating temperature, then check fluid levels again.
