- Disconnect the negative battery terminal to avoid electrical shorts.
- Allow the engine to cool down before beginning work.

2. Check and Replace Transmission Fluid

Fluid Inspection:
- Remove the transmission dipstick and check the fluid level.
- Check the fluid color and smell; burnt or dark fluid indicates a need for replacement.
Fluid Replacement:
- If necessary, drain the old transmission fluid using a drain pan.
- Replace with manufacturer-recommended transmission fluid, typically Honda ATF DW-1.
- Refill the transmission with the correct amount of fluid as specified in the owner’s manual.

3. Inspect and Repair Electrical Connections

Visual Inspection:
- Inspect wiring harnesses and connectors for damage, fraying, or corrosion.
Repair Damaged Wires:
- If any damage is found, repair or replace the affected wiring and connectors.

4. Test and Replace the Transmission Control Module (if necessary)

Module Testing:
- Use a multimeter to test the power and ground connections to the TCM.
- If the TCM is faulty, remove it by unscrewing the mounting bolts and disconnecting the wiring harness.
Replacement:
- Install the new TCM and connect all wiring, ensuring a secure fit.

5. Reset the Check Engine Light

Reconnect the negative battery terminal and use the OBD-II scanner to clear the P0700 code from the system.
