Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle's battery to prevent electrical shorts.
Ensure the engine is cool before starting work.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick; remove it and check the fluid level.
2. If fluid is low or contaminated, drain the transmission fluid using a fluid extractor.
3. Replace with the manufacturer-recommended transmission fluid (Toyota ATF WS).
4. Recheck the fluid level with the dipstick after filling.

3. Inspect and Repair Wiring/Connectors

Sub-steps:
1. Visually inspect the wiring harness and connectors for any signs of fraying, corrosion, or damage.
2. If damaged, repair or replace the affected wiring or connectors as necessary.
3. Use dielectric grease on connectors to enhance corrosion resistance.

4. Replace Transmission Control Module (if necessary)

Sub-steps:
1. Locate the transmission control module (typically under the dashboard or in the engine bay).
2. Disconnect the wiring harness from the old module.
3. Remove the module using the appropriate socket size (usually 10mm bolts).
4. Install the new module in the reverse order, ensuring it is securely fastened and connected.
5. Reconnect the battery.

5. Clear Codes and Test Drive

Sub-steps:
1. Use the OBD-II scanner to clear the P0700 code and any other transmission-related codes.
2. Start the vehicle and conduct a test drive to check for proper shifting and to ensure the check engine light does not reappear.
