Solution

Solution

1. Preparation

  • Gather all necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and the engine is off.
  • Disconnect the negative terminal of the battery.

2. Transmission Fluid Change

  • Sub-steps:
    1. Remove the transmission drain plug and allow the old fluid to drain completely into a suitable container.
    2. Replace the drain plug and torque to the manufacturer’s specification (usually around 30 ft-lbs).
    3. Refill the transmission with the appropriate type of fluid (typically Honda ATF DW-1) through the dipstick tube.
    4. Start the engine and let it idle, shifting through all gears to circulate the new fluid.
    5. Recheck the fluid level and add more if necessary.

3. Inspect and Repair Wiring/Connectors

  • Sub-steps:
    1. Visually inspect the wiring harness connected to the TCM and transmission for any frays or shorts.
    2. Use a multimeter to test for continuity in the wiring.
    3. Repair or replace any damaged wires or connectors as needed.

4. Replace Transmission Control Module (if necessary)

  • Sub-steps:
    1. Locate the TCM, typically found near the transmission or under the dashboard.
    2. Disconnect the electrical connectors from the TCM.
    3. Remove the mounting bolts and take out the faulty TCM.
    4. Install the new TCM by reversing the removal steps.
    5. Reconnect all connectors and ensure they are secure.

5. Reset the Check Engine Light

  • Sub-steps:
    1. Reconnect the negative battery terminal.
    2. Use the OBD-II scanner to clear the P0700 code and any other related codes from the system.
