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

Solution

1. Preparation

• Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, fluid catch pan, and safety glasses.
• Park the vehicle on a level surface, engage the parking brake, and disconnect the battery to ensure safety.

2. Check and Replace Transmission Fluid

1. Check Fluid Level
   • Remove the dipstick and wipe it clean.
   • Reinsert the dipstick and remove it again to check fluid level; add fluid if low.
2. Fluid Change (if contaminated)
   • Place a fluid catch pan under the transmission.
   • Remove the transmission drain plug and allow fluid to drain completely.
   • Replace the drain plug and torque to specification (typically around 30-40 lb-ft).
   • Refill with the manufacturer-recommended transmission fluid through the dipstick tube.

3. Inspect and Replace TCM

1. Remove TCM
   • Locate the TCM, typically found near the transmission or under the dashboard.
   • Disconnect the electrical connectors carefully.
   • Remove the mounting bolts using a socket set and take out the TCM.
2. Install New TCM
   • Position the new TCM in place and secure it with the mounting bolts.
   • Reconnect the electrical connectors ensuring they are secure and free from corrosion.

4. Clear Codes and Test Drive

1. Clear Codes
   • Reconnect the battery.
   • Use the OBD-II scanner to clear the P0700 code and any other related codes.
2. Test Drive
   • Start the engine and allow it to warm up.
   • Test drive the vehicle to ensure proper shifting and to check if the check engine light returns.
