Remove the transmission dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the fluid level.
If low, add the recommended transmission fluid (Toyota Type T-IV or equivalent) until it reaches the correct level.
If the fluid is dark or has a burnt smell, consider performing a transmission fluid change.

3. Repair Wiring and Connectors

Visually inspect and repair any damaged wiring or corroded connectors leading to the transmission control module.
Use dielectric grease on connectors to prevent future corrosion.
Ensure all connections are secure and free from moisture.

4. Replace Transmission Control Module (if necessary)

Locate the transmission control module, typically found under the dashboard or near the transmission.
Disconnect the electrical connectors from the module.
Remove the mounting bolts securing the module and take it out.
Install the new transmission control module by reversing the removal steps.
Reconnect all electrical connectors.

5. Clear Codes and Test Drive

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear the P0700 code.
Start the vehicle and conduct a test drive to ensure proper shifting and functionality.
